    摘要： Pigment concentrates comprising a pigment, a liquid carrier medium and a diol alkoxylate of the general formulae (I), (II) and/or (III) are described in conjunction with methods of preparing the same. The diol alkoxylates described and used herein are of the general formulae (I), (II) and/or (III): wherein each of R1, R2, R3, R5, R7 and R8 independently represents a hydrogen atom or an alkyl group having from 1 to about 36 carbon atoms, with the proviso that both R1 and R2 are not simultaneously hydrogen atoms and the total number of carbon atoms in R1 and R2 is from about 6 to about 38, and with the proviso that both R3 and R5 are not simultaneously hydrogen atoms and the total number of carbon atoms in R3 and R5 is from about 6 to about 38, wherein R4 represents a linear or branched alkylene group having from about 2 to about 12 carbon atoms or (—CH2—CHR6—O)z—, wherein R6 represents a hydrogen atom or a methyl group, wherein each of x and y independently represent a number of from about 1 to about 200, z represents a number of from about 1 to about 20, n represents a number of from about 2 to about 12, and wherein the sum of x+y is a number of from about 5 to about 200.

    摘要： Ammonium fatty acid hydroxyalkanesulfonates are made by a process in which (a) ammonium hydroxyalkanesulfonate corresponding to general formula (I):HO--(C.sub.n H.sub.2n)--SO.sub.3 NH.sub.4 (I)wherein n=2 to 4, is subjected to the esterification reaction with a fatty acid corresponding to the formula (II)R--COOH (II)wherein RCO is an aliphatic, linear or branched acyl radical containing 6 to 18 carbon atoms, in the presence of an esterification catalyst, characterized in that (a) before the esterification reaction, the starting compounds corresponding to formulae (I) and (II) are dried at a temperature of 120.degree. C. to 160.degree. C. and under a pressure of 100 to 700 mbar; (b) the esterification reaction is carried out at a temperature above 160.degree. C. to 195.degree. C. and under a pressure of 250 mbar to atmospheric pressure; (c) water of solution and water of reaction formed are directly removed from the reaction mixture; (d) the catalyst is neutralized with a base on completion of the reaction.
