Process for dewatering fine-particle solids suspensions using dialkyl carbonates |
摘要 |
Fine-particle solids suspensions can be dewatered by a process in which dialkyl carbonates corresponding to formula (I) <IMAGE> (I) in which R1 and R2 independently of one another represent alkyl and/or alkenyl groups containing 1 to 22 carbon atoms and m and n independently of one another stand for 0 or numbers of 1 to 10, are used as auxiliaries. The auxiliaries are readily biodegradable, extremely low-foaming and are distinguished by a low solidification point.
