Abstract
547,067. Monohalogenacrylnitriles. WING- FOOT CORPORATION. Feb. 13, 1941, No. 1978. Convention date, March 15, 1940. [Class 2 (iii)] α - Monohalogenacrylnitriles are obtained by heating α : # - dihalogen propionitriles. In an example, α : # - dibrompropionitrile, prepared by addition of bromine to acrylnitrile in carbontetrachloride, is converted into # - monobromacrylnitrile by repeated fractional distillation. Specifications 462,181 and 514,912 are referred to. The Specification as open to inspection under Sect. 91 comprises also the addition of a tertiary amine, e.g. trimethylamine, picoline or quinoline during its treatment. This subjectmatter does not appear in the Specification as accepted.
