Abstract: Production of polyisobutenes comprises the cationic polymerization of isobutenes or isobutene containing hydrocarbon streams in the liquid phase in the presence of boron trifluoride catalyst whereby the catalytic effectiveness of the boron trifluoride is terminated at a desired point in time by the addition of a deactivator comprising a carbonyl compound, optionally together with water. A process for the production of polyisobutenes comprises the cationic polymerization of isobutenes or isobutene containing hydrocarbon streams in the liquid phase in the presence of boron trifluoride catalyst whereby the catalytic effectiveness of the boron trifluoride is terminated at a desired point in time by the addition of a deactivator comprising a carbonyl compound of formula (1), optionally together with water. R -(C=O)-R (1) R ,R = H, 1-12C alkyl, arylalkyl or aryl or 3-7C alkylene

Abstract: The invention relates to a method for separating contaminants from 3-(2'-acetoxy-ethyl-dihydro-2(3H)furanone (I), whereby the 3-(2'-acetoxy-ethyl-dihydro-2(3H)furanone containing the undesired contaminants is first produced using known methods by acetylization of 3-(2'-hydroxy-ethyl-dihydro-2(3H)furanone and is subsequently treated with strong mineral acids. Finally, the decomposition products of the undesired contaminants of (I) are separated.
