Abstract: A process for preparing halogen-free, reactive polyisobutene having a terminal double bond content of more than 60 mol % and an average molecular weight Mn of 800-3000 dalton by cationic polymerization in the liquid phase of isobutene over an acidic, essentially halogen-free heterogeneous catalyst, wherea) a hydrocarbon mixture of essentially C4-hydrocarbons comprising isobutene in an amount of from 10 to 80% by weight is used as the starting material andb) polymerization is carried out continuously at from -30 to 0° C. with average starting material residence times of one hour or less, where the temperature and the residence time are selected such that the isobutene conversion is less than 60% and, after separation from the resulting polyisobutene, the isobutene is either enriched in the partially converted hydrocarbon mixture and returned to the polymerization or passed to another isobutene reaction coupled with the polymerization.

Abstract: The invention relates to a method for producing alkylene glycol or a mixture of two different alkylene glycols, wherein a reaction mixture containing at least one alkylene oxide or a mixture of two or more different alkylene oxides, a catalyst and water are made to react. The catalyst can not be dissolved in the reaction mixture and has at least one covalently linked acid functional group and at least one covalently linked basic functional group. The invention also relates to a moulded body with at least one acid group and at least one basic functional group, whereby the functional groups are covalently linked to the support.

Abstract: Preparation of O-(2-hydroxyalkyl) oximes of formula (I), (R and R are alkyl or R and R and the common C atom are 5-membered to 7-membered cycloalkyl; R is alkyl) by causing a ketoxime II to react with an olefin oxide III in the presence of a tertiary amine or with a carbonate IV in the presence of a catalyst. The end products (I) are suitable for use as intermediates for crop protection agents.
