Abstract

1,168,242. Pyridium salts. IMPERIAL CHEMICAL INDUSTRIES Ltd. 20 Sept., 1967 [13 Oct., 1966], No. 45808/66. Addition to 1,070,295. Heading C2C. Pyridium salts are prepared by a process comprising the step of reacting in the liquid phase a possibly substituted glutaraldehyde, or a precursor thereof such as a 2-alkoxy-3,4- dihydro-2H-pyran, with a primary amine or salt thereof in presence of O 2 . Exemplified products are N-methyl- and N-benzyl-pyridinium chlorides, which are obtained by adding HC1 to the initial reaction products, apparently containing the corresponding acetates due to the use of HOAc as reaction medium. Reference has been directed by the Comptroller to Specification 1,099,642.
