    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 and R , independently from one another, mean C1- to C4-alkyl or R and R together mean a C4- or C5-alkylene chain. According to the inventive method, hydrogen chloride is added during and/or after the conversion.

    Abstract: Process for the purification of carbonyl chlorides which have been prepared by reacting carboxylic acids with phosgene or thionyl chloride in the presence of a catalyst adduct, in which the carbonyl chlorides are treated with a hydrohalide of carboxamides of the formula (I)in which R is hydrogen or C1- to C3-alkyl; R and R independently of one another are C1- to C4-alkyl, or R and R together are a C4- or C5-alkylene chain, and the carbonyl chloride purified in this way is isolated by separation off from the carboxamide hydrohalide phase.

    Abstract: In a process for finishing neopentyl glycol by cooling, crystallizing and comminuting a neopentyl glycol melt and subsequent packing of the resulting neopentyl glycol particles in storage or transport containers, the melt is cooled at the commencement of cooling for at least 1/10 minutes without use of a coolant or with use of a coolant having a temperature in the range from 50 to 120° C. and the product is packed at a temperature below 30° C.
