Abstract: A novel process for recovering glycols from used glycol-containing technical fluids is disclosed. Used glycol-containing technical fluids has added to it an organic solvent which forms with the glycols to be separated off, an azeotropic mixture which has a lower boiling point than the glycol itself. This azeotropic mixture is then distilled off. A typical used glycol- containing technical fluid as used is antifreeze. The preferred organic solvent is a xylene or a pseudocumene. Prior to the addition of solvent which forms the azeotropic mixture with the glycol, a water portion in the used glycol-containing technical fluid, if present, can also be advantageously first removed by distillation.

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.
