Abstract: A process for the storage and transport of chloroformic acid esters in tanks or pipelines which have a plastic inside surface, which comprises using a plastic having a total nitrogen content of from 0 to 100 ppm by weight, where this plastic forms from 20 to 100% of the inside surface, and the use of tanks or pipelines of this type for the storage and transport of chloroformic acid esters.

Abstract: In the production of chloroalkanoyl chlorides (I) with a (substituted) 1-10 carbon (hetero)alkylene chain by reacting a lactone (II) with hydrogen chloride (HCl) and phosgene (COCl2) in the presence of a catalyst, HCl is introduced before and/or during addition of COCl2, starting when the temperature reaches >= 60 deg C, and the catalyst is a pyridine compound. In the production of chloroalkanoyl chlorides of formula (I) with a (substituted) 1-10 carbon (hetero)alkylene chain by reacting a lactone of formula (II) with hydrogen chloride (HCl) and phosgene (COCl2) in the presence of a catalyst, HCl is introduced before and/or during addition of COCl2, starting when the temperature reaches >= 60 deg C, and the catalyst is a pyridine compound: R , R = H or R; R = halogen, nitro, CN or an organic group containing carbon (C); Y = optionally R-substituted 1-10 C alkylene, which may have a (thio)ether, tertiary amino or keto group in the chain, in which R groups on Y, R and/or R may be linked to form a non-aromatic system.

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: A process for the preparation of pourable choline chloride/silica powders by mixing silica with choline chloride and, where appropriate, drying this mixture, wherein spray-dried or fluidized bed-dried silica which has a particle size of from 30 to 250 mu m is mixed with an aqueous choline chloride solution which contains from 70 to 80% by weight, based on the solution, of choline chloride and is at from 40 DEG to 80 DEG C., thereafter from 0.05 to 0.4% by weight, based on the mixture, of magnesium stearate or calcium stearate is added and, if appropriate, the resulting mixture is dried.

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.
