실험 절차

The procedure of Example 10 was repeated using 33.6 grams (0.3 moles) of chlorobenzene, 41.1 grams (0.3 moles) of phosphorus trichloride and 22.2 grams (0.05 moles) of phosphorus pentasulfide. The reaction mixture was heated at 300° C. for 7 hours. The product, phenylphosphonothioic dichloride, in a yield of 18.3 grams, was isolated by distillation and redistillation, and had a boiling point of 58° C. and 62° C. (0.02 millimeters of mercury) and an nD25 of 1.6235 as against the reported nD25 of 1.6220 for phenylphosphonothioic dichloride.
