    摘要: Fine-particle solids suspensions can be dewatered by a process in which dialkyl carbonates corresponding to formula (I) ##STR1## in which R.sup.1 and R.sup.2 independently of one another represent alkyl and/or alkenyl groups containing 1 to 22 carbon atoms andm 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.

    摘要: Finely divided solids suspensions can be dewatered by adding to the solids suspension a mixed hydroxy ether of the formula ##STR1## wherein R.sup.1 is a linear hydroxy alkyl group containing from 2 to 16 carbon atoms with the hydroxyl group on the carbon atom adjacent to the carbon atom with the ether linkage and R.sup.2 is a linear alkyl group with 1 to 15 carbon atoms with the proviso that the sum of the total carbon atoms in R.sup.1 and R.sup.2 is 5 to 17, R.sup.3 is a linear or branched alkyl group with 1 to 12 carbon atoms and n is a number of from 1 to 20. The mixed hydroxy ethers are readily biodegradable, generate very little foam and have a low solidification point.
