Tetrahydrofuran of чда 2932110000
Tetrahydrofuran (tetramethylene oxide, furanidine) is a chemical substance, cyclic ether.
Colorless, volatile liquid with a characteristic "etheric" odor. An important aprotic solvent. It is widely used in organic synthesis. It is used as a solvent, for example, for polyvinyl chloride, in laboratory practice - instead of ethyl ether in the production of organomagnesium compounds (in particular, vinylmagnesium bromide).
The products of homo- and copolymerization of tetrahydrofuran are raw materials for the production of urethane rubbers. Gamma-butyrolactone is synthesized from THF. In addition, it is used as an anti-crystallization additive for aviation and rocket fuels.
