Abstract: Fuels for spark-ignition engines contain minor amts. of copolymers, of mol. wt. 500-20,000, of maleic anhydride (MA) with (i) 2-40C olefins (A) and/or 3-10C cycloolefins (B), or (ii) 1-30C-alkyl vinyl ethers (C) and/or 3-10C-cycloalkyl vinyl ethers (D), or (iii) (C) and/or (D) and (A) and/or (B); in which the carboxyl gps. of the copolymers are wholly or partly reacted with alkali (ne earth) to form the corresp. salts, and the remaining carboxyl gps. are reacted with alcohols and/or amines with up to 50C to form the corresp. esters, amides or ammonium salts. The copolymers pref. contain at least 3 wt. % alkali or alkaline earth, esp. K. The fuel pref. contains 10-2,000 ppm of the alkali (ne earth) metal salts of the copolymers.

Abstract: The invention relates to fuels for spark-ignition engines, which contain small quantities of copolymers of vinyl alkyl ethers having 1 to 30 carbon atoms in the alkyl group and/or cycloalkyl vinyl ethers having 3 to 10 carbon atoms in the alkyl group with maleic anhydride, and/or copolymers of alkyl vinyl ethers having 1 to 30 carbon atoms in the alkyl group and/or cycloalkyl vinyl ethers having 3 to 10 carbon atoms in the alkyl group and olefins having 2 to 40 carbon atoms and/or cycloolefins having 3 to 10 carbon atoms with maleic anhydride, having an overall molecular mass of from 500 to 20,000 g per mol, some or all of the carboxyl groups in the copolymers being reacted with alkali metal or alkaline earth metal to form the alkali metal or alkaline earth metal salts, and the remainder of the carboxyl groups being reacted with alcohols and/or amines having up to 50 carbon atoms, to give the corresponding ester and/or amide groups and/or ammonium salts.

Abstract: Aliphatic chlorine compounds of the formula X-R1-Cl I where R1 is alkylene which may be interrupted by one or more oxygen atoms and which may be substituted by halogen, alkyl or aryl, and X is hydrogen, chlorine or OR2, where R2 is alkyl, cycloalkyl, aryl or aralkyl, are prepared by decarboxylating chloroformic acid esters or diesters at elevated temperatures by decarboxylating in the presence of a quaternary ammonium or phosphonium salt as catalyst.
