Abstract: A process for the preparation of a color stable C6-12 saturated aliphatic carboxylic acid in which (1) the corresponding aldehyde is oxidized with molecular oxygen to obtain the crude saturated aliphatic carboxylic acid in a liquid mixture, (2) molecular oxygen removed from the crude saturated aliphatic carboxylic acid mixture, and (3) the saturated aliphatic carboxylic acid separated from the molecular oxygen depleted mixture by distillation as a color stable product.

Abstract: A process for the distillation of a mixture which consists to at least 90% by weight of a cyclic N-vinylamide and which comprises a stabilizer, wherein a polyether is added to the mixture before or during distillation and a product is obtained which consists to at least 99.5% by weight of the cyclic N-vinylamide.

Abstract: Process for the continuous hydrogenation of a carboxylic acid (I) to an alcohol (II) by means of hydrogen at a temperature of from 100 to 300° C. and a pressure of 10 to 33 MPa abs in a reactor tube through which axial flow occurs and which has a fixed-bed catalyst which is fixed therein and comprises at least one element from the group consisting of Re, Co and Cu, and in which the carboxylic acid (I) to be hydrogenated is present in a liquid mixture (Ill) comprising the carboxylic acid (I), water and alcohol (II), where the mixture (Ill) has an acid number of from 0.2 to 25 mg KOH/g and comprises at least 15% by weight of water and at least 20% by weight of alcohol (II) and the flow velocity of the flowing liquid calculated on the basis of the geometric cross-sectional area of the empty, catalyst-free reactor tube is from 10 to 50 m/h.
