摘要： The invention relates to a method of controlling a hydrogenation of a starting material in a hydrogenation reactor, in which the amount of hydrogen reacted in the hydrogenation is firstly determined, the ratio of the amount of hydrogen reacted to the amount of starting material fed in is then derived, this ratio is compared with a prescribed value and, finally, at least one process parameter is altered if the ratio of the amount of hydrogen reacted to the amount of starting material fed in deviates by a prescribed amount from the prescribed value.

摘要： The invention relates to a process for preparing 1,6 hexane diol and .epsilo n.- caprolacton from a carboxylic acid mixture containing adipic acid, 6-hydroxy caproic acid and, in small quantities, 1,4 cyclohexane diols . Said mixture is obtained as a by-product of the oxidation of cyclohexane into cyclohexanone/ cyclohexanol with oxygen or gases containing oxygen, by water extraction of the reaction mixture. Said process involves esterification and hydrogenation of a partial stream into hexane diol and cyclization of 6-hydroxy caproic acid esters into caprolacton. According to this process: (a) the monocarboxylic acids and the dicarboxylic acids contained in the aqueous reaction mixture are reacted with a low-molecular alcohol to form the corresponding carboxyli c acid esters; (b) the excess alcohol, water and low-boiling agents of the resultant esterification mixture are released in a first distillation stage; (c) separating into a ester fraction substantially free of 1,4 cyclohexane diols, and a fraction containing at least the greater par t of the 1,4 cyclohexane diols is carried out from the bottom product in a second distillation stage; (d) at least part of a stream substantially containing 6-hydroxy caproic acid ester is separated from the ester fraction in a third distillation stage; (e) the ester fraction fro m (d), from which 6-hydroxy caproic acid ester was at least partially removed, is hydrogenated catalytically and 1,6 hexane diol is extracted by distilling the hydrogenated product in a known manner, and (f) the stream substantially containing 6-hydroxy caproic acid ester is heat ed to temperatures above 200 .degree.C at reduced pressure, thereby causing cyclization of 6-hydroxy caproic acid ester to form caprolacton, and pure e-caprolacton is recovered from the cyclization product by distillation.
