Abstract (en)
[origin: WO9324799A1] Finely divided solid suspensions may be dehydrated by using as auxiliaries dialkyl carbonates of formula (I) in which R?1 and R?2 are mutually independently alkyl and/or alkenyl radicals with 1 to 22 carbon atoms and m and n are mutually independently 0 or numbers from 1 to 10. The auxiliaries are easily biodegradable, generate very little foam and are distinguished by a low solidification point.
