Yield:813-74-1 412.0 g (92%)

Steps:

I.a a.

a. α,α,β-Trichloropropanonitrile Acrylonitrile (150.0 g; 2.82 moles) is chlorinated with chlorine gas (>200.2 g; >5.64 moles) for approximately 8 hours. The reaction temperature is maintained at 25°-30° C. by external water cooling. The progress of the reaction is monitored by GLC analysis until essentially a single peak is obtained in the chromatogram. At this point, the flow of chlorine is discontinued and the reaction mixture is degassed by sparging with a vigorous nitrogen flow for one hour. The crude liquid product is distilled to yield 412.0 g (92%) of α,α,β-trichloropropanonitrile (bp 100° C. ? 125 mm Hg).
