摘要： 1,6-Hexanediol is prepared from a carboxylic acid mixture comprising adipic acid, 6-hydroxycaproic acid and small amounts of 1,4-cyclohexanediols which is obtained as a by-product in the oxidation of cyclohexane to cyclohexanone/cyclohexanol by water extraction of the reaction mixture, by esterification of the acids and hydrogenation whereina) the monocarboxylic and dicarboxylic acids present in the aqueous dicarboxylic acid mixture are reacted with a low molecular weight alcohol to give the corresponding carboxylic esters,b) the resulting esterification mixture is freed of excess alcohol and low boilers in a first distillation stage,c) the bottoms are fractionated in a second distillation stage to give an ester fraction essentially free of 1,4-cyclohexanediols and a fraction comprising at least the major part of the 1,4-cyclohexanediols,d) the ester fraction essentially free of 1,4-cyclohexanediols is catalytically hydrogenated ande) in a pure distillation stage, 1,6-hexanediol is isolated from the hydrogenation product in a manner known per se.

摘要： The continuous esterification of a C.sub.1 -C.sub.8 -alkanol with (meth)acrylic acid in a molar ratio of from 1:1 to 2:1 in the presence of proton-donating catalysts in a homogeneous, liquid, solvent-free phase, in which the water of reaction and resulting alkyl (meth)acrylate are separated off continuously as part of an aqueous azeotropic mixture via the top of a rectification zone attached to the reaction zone, at a top pressure of from 0.1 to 1 atm, and worked up to give pure (meth)acrylate, is carried out by a process wherein the reaction temperature is from 100.degree. to 150.degree. C., the residence time is from 1 to 5 hours and from 5 to 20% by weight, based on the amount of reaction mixture, of sulfuric acid or an equimolar amount, based on such an amount of sulfuric acid, of an organic sulfonic acid is added as a protic acid catalyst to the reaction mixture present in the reaction zone.
