摘要： When saturated with boron trifluoride, certain polyhydric alcohols form adducts which catalyze hydrocarbon alkyl transfer reactions for which boron trifluoride is catalytic. The adduct is recovered from the reaction mixture and recycled, greatly reducing boron and fluoride values in the product and in any effluent. Examples include propylation of toluene in the presence of a recycled adduct of boron trifluoride with mannitol or sorbitol, and the oligomerization of decene by a recycled adduct of boron trifluoride with mannitol or butanediol. Some of the catalysts become viscous on cooling and are thus more easily separated from the reaction products which remain in a separate liquid phase.

摘要： Sulfuric acid contaminated with boron and fluoride values such as the waste acid of a boron trifluoride process is purified by contacting the contaminated acid with an inert gas to desorb boron trifluoride, and the inert gas is stripped by contacting with an absorbing liquid including concentrated sulfuric acid. Fluosulfonic acid is added to contaminated sulfuric acid at levels approximately three times the molar values of boric acid contaminant as an agent to spring non-volatile boron values. The absorption of boron trifluoride into the absorbing sulfuric acid is improved when it contains boric acid. Preferably the contaminated sulfuric acid to be purified is one portion of the waste liquid and the absorbing liquid is another portion of the waste liquid of a boron trifluoride manufacturing process. Boric acid is added to the absorbing liquid, then boron trifluoride is stripped from the inert gas and absorbed into the absorbing liquid. The absorbing liquid along with stripped boron trifluoride is recycled to a boron trifluoride manufacturing process. The inert gas can be recycled to the desorbing step.
