Abstract: Liquid mixtures containing aliphatic alcohols are separated, by distillation, into a higher-boiling alcohol-containing fraction and a lower-boiling fraction containing the other liquids, by carrying out the fractionation in the presence of water and of an alkanal and, over about 3/4 of the column height, in the presence of a non-volatile or only slightly volatile acid.

Abstract: The processing properties of isobutene polymers when reacted with maleic anhydride are improved by a method in which these polymers are brought into contact, for an effective period, with aluminum oxide and/or a completely or partially hydrated aluminum oxide at 50 DEG -280 DEG C., and/or with boron oxide and/or a completely or partially hydrated boron oxide and/or with titanium dioxide and/or a partially hydrated titanium dioxide and/or with a completely or partially hydrated silicon dioxide at 0 DEG -280 DEG C.

Abstract: Isobutylene homo- and copolymers with olefinically unsatd. monomers are produced by polymsn. in liq. phase in a polymsn. zone at a pressure of 0.2-20 bar and at -130 to 60 deg.C, in the presence of (i) 0.01-20m Mole (on monomer) of a boron halide catalyst; (ii) a cocatalyst and opt. a polymsn. accelerator in a molar ratio of 0.5 boron halide:200 cocatalyst and opt. polymerisation accelerator; (iii) 0-90 wt.% inert solvent, and removing heat of polymsn. by cooling. The new feature is the use of a carboxylic acid anhydride or halide as the cocatalyst. Pref. the cocatalyst is a 4-18C aliphatic or aromatic opt. halogen substd. anhydride or a 2-12C carbonyl halide. Esp. trifluoroacetic, trichloroacetic, benzoic, phthalic, succinic, pivalic, maleic or (meth)acrylic anhydrides; acetyl fluoride, acetyl chloride, acetyl bromide, benzoyl chloride pivaloyl chloride or acryloyl chloride are claimed as co-catalyst.
