Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an alcohol for an ester plasticizer by using a hydrocarbon mixture. SOLUTION: This method for producing an alcohol mixture comprises (a) reacting a hydrocarbon mixture containing cyclopentene and at least one kind of an acyclic monoolefin by a metathesis reaction, (b) isolating an olefin fraction substantially containing 6-12 carbon atoms from the metathesis reaction mixture, (c) at least partially hydrogenating two or more unsaturated compounds contained in the olefin fraction selectively into a monoolefin, if necessary and (d) hydroformylating the monoolefin fraction selectively hydrogenated, if necessary, by a catalytic action by a reaction using carbon monoxide and hydrogen and hydrogenating the hydroformylated substance. The method is useful for producing a plasticizer or a plasticizer mixture for a molding material.

Abstract: A description is given of polyisocyanates of the formula I in which R and R' are identical or different and are alkyl groups having 1-4 carbon atoms and n is on average from 1.5 to 5 and also of a process for preparing these polyisocyanates in which a polyamine of the formula II in which R, R', and n are as defined above, is reacted with phosgene. The new polyisocyanates are suitable for producing crosslinked polyurethanes from reaction mixtures with low solvent content and for producing coating compositions or adhesives. Also described are the coating compositions and adhesives, and their use.

Abstract: The invention describes a process for the preparation of novel surfactant alcohols and surfactant alcohol ethers by derivatization of olefins having from about 10 to 20 carbon atoms or of mixtures of such olefins to give alkanols, and optional subsequent alkoxylation, which comprises subjecting a C 4 -olefin mixture to metathesis, dimerizing the resulting olefins, and then derivatizing them to give surfactant alcohols, and optionally alkoxylating said alcohols. The olefin mixture obtained in the dimerization has a high proportion of branched components and less than 10% by weight of compounds which contain a vinylidene group. invention further describes the use of the surfactant alcohols and surfactant alcohol ethers to give surfactants by glycosylation or polyglycosylation, sulfation or phosphation.
