Abstract

541,375. Cyanacrylic acid esters. CRAWFORD, J. W. C., McLEISH, N., WOOD, T. K., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 23, 1940, No. 9131. [Class 2 (iii)] Esters of #-cyanoacrylic acid are produced by re-acting esters of α-chloracrylic acid with an alkali or alkaline earth cyanide in the presence of water or a water-miscible solvent of the chloracrylic ester, at temperatures not greatly above atmospheric, such as 0-30‹C. The re-action mixture may be buffered to a weakly alkaline state for instance by means of a bicarbonate or borate, and an anti-polymerization catalyst such as hydroquinone or aniline may be added. When an alkaline earth cyanide is used it may be made in situ. The product may be treated by fractional distillation and cis and trans forms may be separated by fractionation. Examples are given.
