Boron trifluoride-methanol solution Chemical Properties,Usage,Production

Chemical Properties

colorless to amber solution

Chemical Properties

Boron trifluoride etherates: (compounded with methyl ether) is moisture-sensitive, corrosive, flammable liquid.

Uses

Reagent for the GC analysis of ritalinic acid. Alternative to Cl₂CHCO₂H for synthesis of purine rich oligomers.
Lewis acid used in the preparation of geminal bis-peroxides from ketals and enol ethers with t-butyl hydroperoxide. Reagent used for the mild deacetylation of amines.

Uses

It was used in transmethylation of 1,2-Diacylglycerol (DAG) containing fractions which were purified using HPLC. It may be used to treat lipids during GC analysis done for determination of fatty acid methyl esters and dimethylacetals.

Uses

Trifluoro(methanol)boron is a reagent used for the GC analysis of ritalinic acid.

General Description

Boron trifluoride-methanol (BF-M) is an esterification reagent. BF-M is a powerful acidic catalyst for the esterification of the fatty acids. It easily cleaves acetylated dyes resulting in free amino groups. BF-M catalyzed trans esterification of vegetable oils forms biodiesel.

Potential Exposure

Used as a catalyst.

Shipping

Diethyl: UN2604 Boron trifluoride diethyl etherate, Hazard class: 8; Labels: 8—Corrosive material, 3—Flammable liquid. Dimethyl: UN2965 Boron trifluoride dimethyl etherate, Hazard class: 4.3; Labels: 4.3— Dangerous when wet, 8—Corrosive material, 3— Flammable liquid.

Incompatibilities

Reacts with air forming corrosive hydrogen fluoride vapors. Incompatible with oxidizers (may cause fire and explosion), water, steam or heat, forming corrosive and flammable vapors. Peroxide containing etherate reacts explosively with aluminum lithium hydride, magnesium tetrahydroaluminate. Mixtures with phenol react explosively with 1,3-butadiene. Presumed to form explosive peroxides.
