Abstract: Recovery of glycols from used glycol-contg. technical fluids comprises (a) adding an organic solvent to the glycol-contg. fluids to form an azeotropic mixt. with the glycols which has a lower b.pt. than the glycol itself; and (b) distilling off the azeotropic mixt.

Abstract: Acyloxybenzenesulfonic acids and their alkali metal and alkaline earth metal salts are prepared by a process comprising sulfonation of a phenyl ester in the presence or absence of a small amount of a complexing agent for the sulfonating agent SO3 or chlorosulfonic acid, subsequent acylation and, if desired, neutralization to give the alkali metal or alkaline earth metal salt, and, if required, subjecting the latter to oxidative bleaching before drying.
