Methoxypropanol, a by-product in the manufacture of propylene glycol monomethyl ether (PGME)

Methoxypropanol is a by-product in the manufacture of propylene glycol monomethyl ether (PGME).
Propanol (PGME), a cholemethyl used in products such as Methoxypropanol, industrial and paints, is present as an impurity.

Currently, Methoxypropanol is not produced commercially for swarming in Canada, but is imported.

As a new type of eco-friendly reaction medium and green solvent, ionic liquids (ILs) have received widespread attention in these years owing to their particular properties such as negligible vapor pressure, wide liquid range, excellent solubility, high catalytic activity and good selectivity .
The utilization of ILs as catalysts and media have been successfully implemented in various chemical processes .
For example, Rogers et al.
found that chloride based ILs could efficiently dissolve cellulose, and resultant solution contains as high as 25 wt% cellulose, which indicated that ILs were economical and effective in comparison with traditional methods.
found that the isobutane alkylation reaction catalyzed by a composite IL could approach a reaction balance of 20 s at 15 °C. Therefore, the ILs being as a green medium shows a very attractive prospect for chemical process intensification.

As a type of propylene glycol methyl ether (PGME), Methoxypropanol shows a much lower toxicity and influence on the environment .
Thus it has been widely used as a versatile solvent for painting, adhesive, printing inks, etc. in the chemical industries .
Methoxypropanol is generally produced by the alcoholysis reaction of propylene oxide (PO) with methanol using base catalysts.
Nevertheless, the conventional base catalysts such as NaOH and Na2CO3 usually facilitated the formation of byproduct 2-methoxy-1-propanol and resulted to low catalytic selectivities for synthesis of 1-methoxy-2-propanol.
In our previous work , we reported that a tetrabutylphosphonium IL acted as an efficient catalyst for obtaining PGME with a yield of 93% at 6 h compared with other kinds of catalysts .
Despite the IL possessing excellent performance, the least of perfection is that there still needs a long reaction time (6 h) in the conventional stirred reactor for the production of 1-methoxy-2-propanol.
Therefore, the challenge remains regarding whether a new intensified process can be developed for highly efficient synthesis of 1-methoxy-2-propanol.

Recently, the development of microreactor technologies has gained widely attention for chemical reaction engineering owing to the requirement of process intensification and production platforms .
Compared to the traditional reactors, microreactors offer smaller devices volumes, enhanced mass and heat transfer efficiency, improved yields over shorter periods of time, increased process control, greater safety, and flexible production .
Therefore, these miniaturized microreactors have good potential to intensify the alcoholysis reaction for efficient synthesis of 1-methoxy-2-propanol, which would result in a greater yield in a shorter time.

Propylene glycol methyl ether acetate is an industrially important solvent.
In this work, we study the applicability of reactive distillation (RD) for its synthesis in the presence of an ion-exchange resin, Amberlyst 15, as a catalyst.
Simultaneous separation of water during the course of reaction shifts the reaction in the forward direction, which renders cost effectiveness and compactness to the process.
The presence of an azeotrope between methoxy propanol and water complicates the separation, leading to a loss of reactants in the product streams, thereby hampering both conversion and purity.
Toluene is thus used as an entrainer to further intensify the process.
In this work, the intrinsic kinetic parameters are determined from batch reactor data, and used subsequently to simulate the column performance.
An experimentally validated simulator is used to examine the effect of various operating and design parameters.
Reactant and product losses are minimized to negligible levels and a significant increase in the conversion is realized.

Methoxypropanol is a propylene oxide-based glycol ether which is fast evaporating and hydrophilic.
Methoxypropanol has low surface tension as well as excellent solvency and coupling abilities.

Methoxypropanol is produced by reacting propylene oxide with methanol using a catalyst.

Methoxypropanol isprimarily used as a chemical building block for the production of propylene glycol methyl ether acetate.
Methoxypropanol is also used as a solvent in manufacturing processes for the chemical, automotive and agricultural industries and in paint, lacquer and varnishes.
Methoxypropanol is used as a coalescing agent in water-based paints and inks where it promotes polymer fusion during the drying process.

Methoxypropanol is formulated into a wide range of cleaners for industrial and commercial use such as those for ovens, glass, hard surfaces, floors, carpets and upholstery, as well as in speciality sanitation products such as swimming pool cleaners.
Methoxypropanol is also present in many everyday products such as polish, laundry aids, caulk, sealants, pesticides, inks for ballpoint and felt-tip pens, synthetic resin and rubber adhesives.

Methoxypropanol has been widely used in modern industry and consumer products.
Inhalation or skin exposure to methoxy propanol for a long period would bring about safety challenges on human habitat and health.
Ag decorated SnO2 mesoporous material has been synthesized and shown to exhibit high sensitivity and good selectivity to methoxy propanol among other interferential VOC gases.
Density Functional Theory study were conducted to yield insight into the surface–adsorbate interactions and therefore the gas sensing improvement mechanism by presenting accurate energetic and electronic properties for the Ag/SnO2 system.

With extensive industrial applications and natural/anthropogenic emissions of chemical species, volatile organic compounds (VOCs) have become ubiquitous in our environment.
Various types of VOCs emitted from human life products have presented safety issues on human habitats and have been reported to have slow but long-term pathogenic effects on human health.
Propylene glycol ethers, including methoxy propanol, are widely used in modern industry and consumer products.
Paints, inks, solvents, varnishes, hardeners, auxiliary materials, etc. It is reported that the content of methoxy propanol in substances is mostly above 50%.
Prolonged inhalation or skin exposure to extremely high concentrations of methoxy propanol can cause inflammatory changes in the nasal epithelium of healthy subjects or disrupt the mucociliary transport system.
The MAK value of methoxy propanol has been determined as 100 ppm to protect the human body from its irritating effects; 4 In other words, systemic toxicity effects will occur when the methoxy propanol concentration exceeds 100 ppm.
Therefore, a highly sensitive and selective detection of methoxy propanol becomes very necessary for human health and safety, especially for exposed workers in workplaces where this chemical compound is used or produced on a large scale.

As a metal oxide semiconductor material with a wide band gap (Eg = 3.6 eV), SnO 2 has always attracted great attention in the field of gas sensors due to its good conductivity, thermal stability and surface reactivity.
On the one hand, the interaction between the target gas and SnO 2 has been extensively investigated experimentally:
The gas sensing properties of SnO 2 mainly depend on its surface chemical transduction, which includes several steps, including adsorption of the target species and charge transfer between the adsorbate and the sensing material.
On the other hand, doping with noble metals is an effective way to improve the gas sensing properties of pure SNO Ag, for which Ag is an excellent candidate.
Although it is well known that Ag can improve the gas sensing performance of SnO, the mechanism of development remains unclear.
Often attributed to a catalytic effect; However, the material surface, atomic configuration, and chemical environment can have a strong influence on the detection properties, thereby characterizing the Ag/SnO gas detection mechanism poses a necessary challenge to the understanding of the gas detection mechanism of the difficult system.

Density Functional Theory (DFT) studies provide insight into atomic geometries and the nature of chemical bonds and can therefore provide a valuable tool for understanding surface-adsorbate interactions by presenting their correct energetic and electronic properties.

However, our knowledge of the performance of an Ag methoxy propanol gas sensor, DFT calculations, and analysis were best performed on the SnO2 seldom (110), surface.
In one of the previous studies, Ag SnO2 porous material could be synthesized via a two-step synthetic route and then tested for the detection of VOC gases.
This Ag decorated SnO mesoporous material showed high sensitivity and good selectivity towards methoxy propanol among other interfering VOC gases.

In this work, an electron transfer model of an Ag and SnO 2 grain interface is presented to demonstrate the catalytic effect of Ag-doped SnO 2 to detect methoxypropanol gas.
Next, a three-layer adsorption model (TLAM) SnO VOC gas sensor is proposed to investigate the performance mechanism.

Methoxypropanol regulates the drying slowdowns of printing inks.
But two important facts should be noted;

Methoxypropanol (evaporation rate: 22, ether:1) dries faster than ethoxyethanol (evaporation rate 43).
In other words, rather large amounts are required to slow drying.

Methoxypropanol is produced by reacting propylene oxide with methanol using a catalyst.
