Title:
【発明の名称】カルボン酸クロライドの製法,およびその触媒
Document Type and Number:
Japanese Patent JPH07112986
Kind Code:
B2
Abstract:
The invention relates to a new process for the preparation of carboxylic acid chlorides by phosgenation of the corresponding carboxylic acid in the presence of a catalyst. This process is characterized in that the said catalyst is chosen from the compounds represented by the formulae (I) (II) in which R1 to R6, which are identical of different, denote: aliphatic, alicyclic, araliphatic or aromatic radicals, or form, in pairs, with the nitrogen atom to which they are attached or with the N-C-N group, a 5- or 6-membered heterocyclic ring. The process applies to most carboxylic acids. The acid chlorides obtained are known and used to produce radical polymerization initiators or pesticides.
