  • Patent number: 6303823
    Abstract: A process for preparing ketones by so-called “crossed aldol condensation” of a ketone with an aldehyde in the presence of a catalyst system consisting of approximately equimolar amounts of a secondary amine and of a carboxylic acid containing at least 2 C atoms, to form an &agr;,&bgr;-unsaturated ketone, and, where appropriate, subsequent catalytic hydrogenation. The process is used in particular for preparing 6-methyl-3-hepten-2-one by reacting acetone with isovaleraldehyde, and for preparing its hydrogenation product, 6-methylheptan-2-one, which is an important precursor for numerous active substances, in particular for preparing lipid-soluble vitamins such as vitamin E.

  • Patent number: 6300467
    Abstract: The present invention relates to a process for preparing hydroxyl-containing polymers, in particular for preparing polytetrahydrofuran with terminal hydroxyl groups, from the corresponding acyloxy-containing polymers by transesterification with alcohols in the presence of an alkali metal- or alkaline earth metal-containing catalyst, which entails the appropriate acyloxy-containing polymer being introduced together with the alcohol and the catalyst into a first prereactor (I) and converted therein at least partly to the hydroxyl-containing polymer, and the reaction solution being fed into the upper zone (IIa) of a distillation column (II) into whose lower zone (IIb) alcohol in vapor phase is additionally fed. This involves a phase exchange at the coherent and the disperse phase at the transition from the prereactor to the distillation column. Preferably, in addition to the first prereactor, a further 3 prereactors are used which serve as holdup reactors.

  • Patent number: 6300414
    Abstract: The present invention provides an olefin-based block copolymer that has an olefin block that is substantially saturated and at least one (poly)ester or (poly)ether block. The olefin-based block copolymer of the invention can be prepared by reacting a liquid hydroxyl-functional, saturated or substantially saturated olefin polymer with a chain-extension reagent that is reactive with hydroxyl groups and will polymerize in a head-to-tail arrangement of monomer units. The olefin-based block copolymer of the invention can be used to prepare an adhesion promoter that provides excellent adhesion of subsequent coating layers to olefinic substrates like TPO and superior properties as compared to previously used adhesion promoters containing chlorinated polyolefins.
