Abstract: The invention relates to an advantageous method for industrial production of sought-after odoriferous musk root substances 2-cyclododecyl-propanol by reacting cyclododecene in the presence of catalytic amounts of a radical initiator with an excess of propionic acid or propionic acid derivative and subsequent catalytic hydrogenation of the formed 2-cyclododecyl propionic acid or the corresponding 2-cyclododecyl propionic acid derivatives.

Abstract: The invention relates to a process for preparing 1,6 hexane diol and .epsilon.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 carboxylic 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 part 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 from (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 heated to temperatures above 200 ~C at reduced pressure, thereby causing cyclization of 6-hydroxy caproic acid ester to form caprolacton, and pure .epsilon.caprolacton is recovered from the cyclization product by distillation.

Abstract: The proposed production of 1,6-hexane diol involves the following steps: a) epoxybutadiene is reacted in the presence of a metathesis catalyst, ethene being broken down to bisepoxihexatrienes of formulae (Ia) and (Ib); and b) these bisepoxihexatrienes are then hydrated with hydrogen to form 1,6-hexane diol.

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.
