    摘要: A novel process for producing 2,3,5-trichloropyridine is described. The process comprises the addition reaction of trichloroacetaldehyde with acrylonitrile in the presence of a catalyst, and the subsequent cyclization of the intermediately formed 2,4,4-trichloro-4-formylbutyronitrile, with the splitting-off of water, to give 2,3,5-trichloropyridine.2,4,4-Trichloro-4-formylbutyronitrile occurring as an intermediate product in the process according to the invention is a novel compound. It can be produced by the addition reaction of trichloroacetaldehyde with acrylonitrile in the presence of a catalyst.2,3,5-Trichloropyridine can be used as intermediate for the production of herbicidal active substances.
