Method for separating alkali metal ions from alkoxylates

In a process for isolating alkylene glycol having a low aldehyde content, in which a mixture comprising alkylene glycol is subjected to a final distillation, formic acid or a formate or a mixture of two or more formates or a mixture of formic acid and one or more formates is present in the mixture comprising alkylene glycol.

Method for producing alkylene glycol with a low carbonyl compound content

The present invention relates to an alkoxylated polyalkyleneimine soil dispersant having the formula:

Propoxylated/ethoxylated polyalkyleneimine dispersants

A process for recovering glycols from used glycol-containing technical fluids, especially from used antifreeze comprises adding to the used glycol-containing technical fluids an organic solvent which forms with the glycol to be separated off an azeotropic mixture which has a lower boiling point than the glycol itself and distilling off this azeotropic mixture.

Recovery of glycols from used glycol-containing technical fluids

A process for the continuous production of 1,3-dioxolan-2-ones such as ethylene carbonate or propylene carbonate by reacting a corresponding oxirane with carbon dioxide in the liquid phase in the presence of a catalyst comprises conducting the reaction in a two-part reactor in whose first part the reaction is taken with backmixing to a conversion of not less than 80% of the oxirane II and in whose second part the reaction is completed under nonbackmixing conditions, and passing the carbon dioxide in countercurrent to the oxirane II in the entire reactor.
