Abstract: The invention relates to polyisocyanates of general formula (I), wherein R and R' are the same or different and mean alkyl groups having 1-4 C atoms and n is a number that amounts to 1.5 to 5 on average. The invention also relates to a method for producing said polyisocyanates. According to the inventive method, a polyamine of formula (II), wherein R, R' and n have the aforementioned meaning, is converted with phosgene. The novel polyisocyanates are suitable for producing cross-linked polyurethanes from reaction mixtures having a low content of solvents and for producing coating means or adhesives. The invention further relates to the coating means and adhesives and the use thereof.

Abstract: The invention relates to a method for producing acid chlorides by converting carboxylic acids with carbon oxychlorides or thionyl chloride in the presence of a catalyst adduct of an N,N-disubstituted formamide of general formula (I) and carbon oxychloride or thionyl chloride. In the formula, R?1 and R2¿, independently from one another, mean C¿1?- to C4-alkyl or R?1 and R2¿ together mean a C¿4?- or C5-alkylene chain. According to the inventive method, hydrogen chloride is added during and/or after the conversion.

Abstract: The invention relates to a method for chlorinating ketones which apart from the carbonyl group are inert in relation to triarylphosphine dichlorides, except cyclopropyl methyl ketone. According to said method the ketones are reacted with a chlorinating agent in the presence of triarylphosphine oxides and the quantity of triaryl phosphine oxide, in relation to the quantity of ketone, is between 0.1 and 10 mol. %. The ketones preferably have at least one CH acid proton in the α position in relation to the carbonyl group.
