Abstract: The invention relates to a method for producing o-choromethyl benzenecarbonyl chlorides of formula (I), wherein R -R can be the same or different and stand for hydrogen, C1-C4-alkyl, halogen or trifluoromnethyl, by converting benzocondensed lactones of formula (II), wherein R -R have the aforementioned meaning, with gaseous or liquid phosgene and the dimers or trimers thereof. The inventive method is characterized in that the conversion is carried out in the presence of catalytical amounts of a Lewis acid and catalytical amounts of a phosgenation catalyst

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: A description is given of polyisocyanates of the formula I in which R and R' are identical or different and are alkyl groups having 1-4 carbon atoms and n is on average from 1.5 to 5 and also of a process for preparing these polyisocyanates in which a polyamine of the formula II in which R, R', and n are as defined above, is reacted with phosgene. The new polyisocyanates are suitable for producing crosslinked polyurethanes from reaction mixtures with low solvent content and for producing coating compositions or adhesives. Also described are the coating compositions and adhesives, and their use.

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: The invention relates to a method for producing carbonyl diimidazoles of general formulas (Ia), (Ib), (Ic) or mixtures thereof, whereby R represents hydrogen or a C1-C4 alkyl radical and R represents hydrogen or a methyl radical. According to the invention, stoichiometric quantities of an organic nitrogenous base which comprises a lower pKb value than imidazole is added to the reaction mixture with regard to the imidazoles by reacting at least one imidazole of general formulas (IIa) and (IIb) in which R and R have the aforementioned meanings with phosgene in an inert solvent.

Abstract: Propargyl chloride (I) is prepared continuously by reaction of propargyl alcohol (II) with a chlorination agent, in the presence of a catalyst (0.1-10 mol.% based on the amount of (II)), at 40-70 deg C. Continuous preparation of (I) comprises reaction of (II) with a chlorination agent in the presence of a catalyst. The chlorination agent, (II) and catalyst (0.1-10 mol.% based on the amount of (II) used) are added continuously into a reaction zone and reacted at 40-70 deg C.
