Abstract: The invention relates to a method for separating a mixture containing butane1,4-diol and at least one other compound from the following group: 4hydroxybutyraldehyde, its cyclical hemiacetal and its cyclical whole acetals with at least one other alcohol, by distillation. The distillation is carried out in the presence of a compound which acts as an alkali. The mixture to be separated preferably contains a cyclical whole acetal of 4hydroxybutyraldehyde with the other alcohol, this alcohol having a lower boiling temperature than butanediol and being in free form. The method is especially suitable for distilling and separating mixtures produced in the hydrogenation of maleic acid derivatives.

Abstract: The invention relates to a method for hydrogenating a benzene polycarboxylic acid or a derivative thereof or of a mixture comprised of two or more thereof with a gas containing hydrogen in the presence of a catalyst. Said catalyst comprises ruthenium as an active metal which is deposited alone or together with at least one metal of subgroups I, VII, or VIII of the periodic table on a support, whereby the support contains macropores. The invention also relates to novel hydrogenated products obtained by hydrogenating benzene polycarboxylic acid (derivatives) and to the use thereof as plasticizers in plastics.

Abstract: 2-Cyclododecyl-propanol [sic], which is in demand as musk scent, is prepared in an advantageous industrial process by reacting cyclododecene with an excess of propionic acid or of a propionic acid derivative in the presence of catalytic amounts of a free-radical initiator, and subsequently catalytically hydrogenating the 2-cyclododecylpropionic acid which is formed or the corresponding 2-cyclododecylpropionic acid derivatives.

Abstract: The invention relates to a process for the preparation of 1,6 hexane diol 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 byproduct of the oxidation of cyclohexane into cyclohexanone/ cyclohexanol by water extraction of the reaction mixture. Said process involves esterification of the acids and hydrogenation. According to this process (a) the monocarboxylic acids and the dicarboxylic acids contained in the aqueous dicarboxylic acid mixture are reacted with a low-molecular alcohol to form the corresponding carboxylic acid esters; (b) the excess alcohol and low-boiling agents of the resultant esterification mixture are released in a first distillation stage; (c) separating into an ester fraction substantially free of 1,4 cyclohexane diols and a fraction containing at least the greater part of the 1,4 cyclohexane diols is carried out from the bottom product in a second distillation stage; (d) the ester fraction substantially free of 1,4 cyclohexane diols is catalytically hydrogenated; and (e) in a pure distillation stage 1,6 hexane diol is extracted from the hydrogenated discharge in a known manner.
