Abstract: The invention relates to a process for removing salts from an alkanolic reaction mixture which is obtained in the preparation of alkoxycarbonylaminotriazines and comprises at least one alkoxycarbonylaminotriazine, at least one cyclic and/or acyclic carbonic ester, at least one C 1 -C 13 -alkanol which optionally comprises one or two oxygen atoms as ether bonds and is optionally substituted by C 1 -C 4 -alkyl and/or hydroxyl, and also at least one alkali metal alkoxide or alkaline earth metal alkoxide, with or without melamine and with or without catalyst, in which salts are removed from the reaction mixture by ion exchange over a cation exchanger and/or anion exchanger.

Abstract: A polyisobutylene having a total content of vinylidene double bonds of more than 50 mol % and a number-average molecular weight of 500 to 10 000 daltons, where at least 10% of all the vinylidene double bonds in the polyisobutylene are part of one or more side chains composed of at least 2 carbon atoms from the main polyisobutylene chain. Such a polyisobutylene is suitable for production of fuel and lubricant additives.

Abstract: Production of isobutene homo- or copolymers having a number average molecular weight of 500 to 5,000,000 by polymerisation of isobutene or an isobutene-containing monomer mixture in the presence of a Lewis acid or a complex containing a Lewis acid as a polymerisation catalyst, the polymerisation being performed in the presence of at least one hemiacetal or acetal, which can be obtained by protonic acid-catalysed reaction of at least one C1 to C12 hydrocarbyl alcohol with at least one aldehyde or ketone having 1 to 12 carbon atoms.

Abstract: Processes comprising: providing an alkanolic reaction mixture, the alkanolic reaction mixture comprising: at least one alkoxycarbonylaminotriazine; at least one carbonic ester; at least one C1-C13-alkanol, which alkanol may further comprise up to two ether-bound oxygen atoms and may further comprise a substituent selected from the group consisting of C1-C4-alkyls and hydroxyls; and at least one alkali metal alkoxide or alkaline earth metal alkoxide; and subjecting the alkanolic reaction mixture to extraction with a polar extractant such that at least a portion of polar/ionic components present in the reaction mixture are removed, wherein the polar extractant is less than entirely miscible with an organic phase of the reaction mixture, to form an alkanolic phase comprising the at least one alkoxycarbonylaminotriazine and a polar phase comprising the polar extractant and the portion of polar/ionic components; and wherein the extraction is carried out with one or more selected from the group consisting of mixer/settler units, columns, centrifugal field separation extractors, and combinations thereof.
