1-Methoxy-2-propanol (Propylene glycol methyl ether, PGME), a glycol ether, can be synthesized by reacting propylene oxide with methanol in the presence of ZnMgAl (zinc-magnesium-aluminium) catalysts.Methoxy propanol (also known as propylene glycol monomethyl ether, 1-methoxy-2-propanol, PM, and PGME), is a colourless liquid that is soluble in water and is highly flammable. It is a methoxy alcohol derivative and has a formula of C4H10O2.Methoxy propanol is produced by the reaction of 1,2-epoxy propane and methanol in the presence of a catalyst, and this is then followed by distillation.The worldwide annual production of methoxy propanol is approximately 100,000 to 500,000 tonnes.Methoxy propanol has a specific gravity of 0.924 and a flash point of 33° C and is therefore highly flammable so should be stored in a cool, dry and well-ventilated area that is free from sources of ignition. For transport purposes, methoxy propanol is classified as packing group III and hazard class 3 and is an irritant.Methoxy propanol is predominately used in the manufacture of propylene glycol methyl ether acetate (otherwise known as PMA) and is also used in industrial and commercial products including paints, varnishes, inks, synthetic resin and rubber adhesives, and automotive and oven cleaners. It is also used as a cleaning agent in the LCD and electronics industry.Methoxy propanol, also known as propylene glycol methyl ether, is a clear, colourless liquid with a faint ether-like odour. It is soluble in water and has moderate volatility. Methoxy propanol is a propylene oxide-based glycol ether which is fast evaporating and hydrophilic. It has low surface tension as well as excellent solvency and coupling abilities.Methoxy propanolis produced by reacting propylene oxide with methanol using a catalyst.Methoxy propanol isprimarily used as a chemical building block for the production of propylene glycol methyl ether acetate. It is also used as a solvent in manufacturing processes for the chemical, automotive and agricultural industries and in paint, lacquer and varnishes. It is used as a coalescing agent in water-based paints and inks where it promotes polymer fusion during the drying process.Methoxy propanol 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. It 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.Methoxy propanol and its vapours are flammable. It should be stored in a cool, well-ventilated place away from sources of ignition. It must be isolated from incompatible materials such as strong oxidizers, bases and acids.Methoxy propanol is a mild, but usually temporary, irritant to the eyes. Repeated or prolonged contact with the skin may cause irritation, and in very large amounts skin absorption may cause drowsiness or dizziness. High levels of methoxy propanol vapour may produce eye, nose and throat irritation, and at very high levels may produce anaesthetic or narcotic effects. Unnecessary exposure should be prevented by appropriate work practices and engineering controls, adequate ventilation and by the use of approved personal protective equipment including gloves, clothing and safety goggles and the use of respirators where appropriate to the task being carried out.Methoxy Propanol (PM) is a colourless highly flammable liquid that is soluble in water. It is a methoxy alcohol derivative with the formula of C4H10O2. It is an organic solvent with a variety of industrial and commercial uses. Methoxy Propanol is mainly used in the production of propylene glycol methyl ether acetate (also known as PMA). Similar to other glycol ethers, it is used as a carrier solvent in printing inks. Furthermore is it used as industrial and commercial paint stripper, paints, varnishes and inks.Propylene glycol methyl ether (PGME or 1-methoxy-2-propanol) is an organic solvent with a wide variety of industrial and commercial uses. Similar to other glycol ethers, it is used as a carrier/solvent in printing/writing inks and paints/coatings. It also finds use as an industrial and commercial paint stripper. It is used as an antifreeze in diesel engines.Methoxy Propanol also known as dowanol PM is a glycol commonly used in surface coating formulations. Methoxy Propanol is a non-flammable product with a distillation range of 117-125°C and a specific gravity of 0.921. Our Methoxy Propanol is very pure with less than 0.01 of water content. It is very fast evaporating and has a high water solubility and active solvency. Out of all the glycols, Methoxy Propanol is the fastest evaporating and offers better viscosity reduction than heavier molecular weight glycol ethers.Methoxy Propanol is widely used in coating and cleaning applications, it offers better viscosity in epoxy and high solids acrylic systems, Methoxy Propanol can be used as a coupling agent and solvent for household and industrial cleaners, rust removers and hard surface cleaner. It can also be used in 2-pack epoxies and graffiti removers, and for certain ink and cleaning applications. Methoxy Propanol is also used as an additive in metal degreasing agents and hydraulic fluids.When using Methoxy Propanol it is important to be cautious. It is advised to wear safety glasses and use chemical resistant gloves.

Maternally toxic effects were found with decreased body weights from Day 12 of gestation through the end of the study at 545 ppm. A dose-dependent increase of resorptions, fetal malformations, and variations was observed at 225, 350, and 545 ppm, whereas 145 ppm was devoid of exposure-related effects. The malformation rate at 545 ppm was 100%. The types of malformations mainly consisted of absent phalanges and absent or rudimentary metatarsal bones, malformed ribs, and a unique enlargement of sternebrae. The effects are very similar to those previously found with 2-methoxypropyl-acetate-1. The results of this study may have implications for the quantitative estimation of risks associated with 2-methoxy propanol-1 impurities in the widely used isomer 1-methoxypropanol-2 which itself does not show developmental toxicity.The effect of different coolants on common hose and seal formulations currently in use in heavy-duty engines has been studied. Water, ethylene glycol, and methoxypropanol coolants have been studied in contact with seven different types of elastomers. A brief discussion of the theory behind rubber swell is presented, as are laboratory and field test data. The data indicate that seasonal failure of hoses and seals may be caused by a sudden change in the composition of the coolant.2-methoxypropanol (CAS NO 1589-47-5) used as solvent in adhesives, coated textiles, prints, etc. and it's looking for additional relevant information on possible alternatives.2-methoxypropanol (CAS NO 1589-47-5) used as solvent in adhesives, coated textiles, prints, etc. The purpose of this request is to gather additional relevant information on possible alternatives for the mentioned uses. Methoxypropanol 99%, 1-methoxy-2-propanol solvent for printing inks, diluent for synthetic resins finishing agents in the manufacture of varnishes Standard solvent for water-soluble resins Slowly evaporating, fully mixable.Odorless colorless liquid. Mixes with water.Oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979. p.151-154, 164].methoxypropanol is a methoxy-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.Low toxicity. In high concentrations may be mildly anesthetic. Direct eye contact produces slight irritation.PM / Propylene glycol methyl ether is the fastest evaporating solvent of the glycol ether family. It has a high water solubility, excellent solvent with good coupling properties making it suitable for cleaning solutions and coating applications. This hydrophilic solvent has 100% water solubility and is ideally suited as a coupling agent in a wide range of solvent systems.
