121-43-7 Usage

Health Hazard

May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Purification Methods

Carefully fractionate the borate through a gauze-packed column. Re-distil and collect it in weighed glass vials and seal them. Keep it away from moisture. It undergoes alkyl exchange with alcohols and forms azeotropes, e.g. with MeOH the azeotrope consists of 70% (MeO)3B and 30% MeOH with b 52-54o/760mm, d 0.87. [Charnley et al. J Chem Soc 2288 1952, Gerrard & Lappert Chem Ind (London) 53 1952, Schlesinger et al. J Am Chem Soc 75 213 1953.] It has also been dried with Na and then distilled. [Beilstein 1 IV 1269.]

Uses

As solvent for waxes, resins, oils; catalyst in the manufacture of ketones; analysis of paint and varnish ingredients; as neutron detector gas in the presence of a scintillation counter; as a promoter of diborane reactions.

General Description

A water-white liquid. Denser than water. Flash point 80°F. Vapors heavier than air. Used as a solvent and fungicide for fruit.

Definition

ChEBI: A member of the class of borate esters obtained by the formal condensation of three equivalents of methanol with boric acid.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Air & Water Reactions

Highly flammable. Rapidly decomposes in water.

Reactivity Profile

Borates, such as Trimethyl borate, behave similarly to esters in that they react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters/borates with alkali metals and hydrides.

Thermodynamic modeling of decomposition processes of Trimethyl borate (cas 121-43-7) in different gas mixtures09/04/2019

A thermodynamic modeling on the chemical vapor deposition in the B-C-O-H, B-C-O-H-He and B-C-O-H-N systems was performed. The thermodynamic equilibrium in these systems was calculated by minimization of Gibbs free energy for the conditions: 300 ≤ Tdep, K ≤ 2000; 0.001 ≤ Ptotal, Torr ≤ 760; m...detailed
