Broad range of products for hydrogen storage research, advanced fuel cells and battery applications.

Hydrogen can easily be generated from renewable energy sources and is the most abundant element in the universe.
Hydrogen is produced from various sources such as fossil fuels, water and renewables.

Hydrogen is nonpolluting and forms water as a harmless byproduct during use.
The challenges associated with the use of hydrogen as a form of energy include developing safe, compact, reliable, and cost-effective hydrogen storage and delivery technologies.

Currently, hydrogen can be stored in these three forms: Compressed Hydrogen, Liquid Hydrogen and Chemical Storage.
High purity, submicron and nanopowder forms may be considered.

Organic synthesis:
Trimethyl borate is a useful reagent in organic synthesis, as a precursor to boronic acids, which are used in Suzuki couplings.

These boronic acids are prepared via reaction of the trimethyl borate with Grignard reagents followed by hydrolysis:
ArMgBr + B(OCH3)3 → MgBrOCH3 + ArB(OCH3)2
ArB(OCH3)2 + 2 H2O → ArB(OH)2 + 2 HOCH3

Uses of Trimethyl borate:
Trimethyl borate is also an anti-oxidant in the brazing and solder flux and has been explored as a fire retardant.
Additionally, Trimethyl borate has been examined as an additive to some polymers.

Trimethyl borate is the main reactant in the Brown-Schlesinger method of producing sodium borohydride, and Trimethyl borate is successfully recreated from sodium metaborate (NaBO2) via a sequential process that includes reacting with sulfuric acid, cooling crystallization, and reactive esterification distillation.

The metaborate is first transformed to boric acid (H3BO3) by treating Trimethyl borate with sulfuric acid, obviating the need to synthesize borax (Na2B4O710H2O) in traditional techniques.
Boric acid is separated and purified from coexisting sodium sulphate by cooling crystallization (Na2SO4).

Following that, Trimethyl borate is made by esterifying boric acid with methanol, with reactive esterification distillation used to speed up the process and purify Trimethyl borate .
X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and gas chromatography are used to demonstrate the formation of boric acid and trimethyl borate (GC).
Sodium metaborate could be converted to boric acid at a rate of about 55%, with a manufacturing yield of 74.1 to 96.5% for trimethyl borate esterified from boric acid as-produced.

Trimethyl borateis potassium (sodium) boron hydrogen intermediate.
Vulcanizing agent, wood preservative, catalyst, gelling agent, heat stabilizer, hydrogen flame extinguishing agent, also used for flame retardant treatment of cotton and preparation of active silica, and as a gas chromatographic analysis reagent for carbohydrate derivatives.

Trimethyl borate is intermediate in preparation of metal borohydrides.

Protection of Wood-based Materials:
Trimethyl borate has a high vapour pressure injected into a container containing the wood beneath a vacuum during vapour phase treatments.
Trimethyl borate then volatilizes and diffuses into the wood by combining with any moisture to form methanol and boric acid.

The borate is released during the reaction and is deposited in the wood.
Some methanol and borate remain in the wood when the vacuum is released.
This method has been used to cure a variety of composites, but Trimethyl borate utility is limited because the wood being processed cannot be too wet (moisture content less than 6–8%).

Properties of Trimethyl borate:

Chemical Properties:
Dehydration produces trimethyl borate, which decomposes to methanol and boric acid when coming in contact with water.
In the presence of oxygen, Trimethyl borate burns to generate boron trioxide.
Trimethyl borate emits a vivid green hue in flames, which overpowers other flame colours.

Synthesis of Trimethyl borate:
Trimethyl borate is a boron triester with a single boron atom and three methoxide groups.
Trimethyl borate can be made by mixing a large amount of dry methanol with boric acid, boron oxide, and a tiny amount of sulfuric acid, and heating the mixture to dehydrate Trimethyl borate if necessary.

Due to the extra methanol used, the finished product would be an azeotropic mixture of methanol (25%) and trimethyl borate (75%).
Pure trimethyl borate can be obtained by converting methanol to trimethyl borate with a boron trihalide, such as boron tribromide.
However, the trihalide should be added gradually to avoid hydrolysis of the previously present boron tribromide.

Trimethyl borate is an essential reagent in organic synthesis because Trimethyl borate acts as a precursor to boronic acids.
These boronic acids, used in Suzuki couplings, are made by reacting trimethyl borate with Grignard reagents.
