During the synthesis process, the reaction mixture is alkalized every 45 hours with a 50% aqueous solution of potassium hydroxide (total ml). After the reaction is completed and the reaction mixture is cooled, the lower tetrachloror propane layer is separated and washed with water until the reaction with chlorine ions is negative. The product is dried with anhydrous sodium sulfate and filtered from the drying agent, the excess tetrachloropropane is distilled off in vacuum (10 mm Hg) in a stream of nitrogen at a temperature. The resulting crude product is purified by column chromatography on a gel medium. To this end, 10 g of the product was loaded into a column with silica gel wetted with hexane; target product was eluted with a mixture of hexane and benzene. After distilling off the solvent, the product is obtained in the form of an oily, light yellow liquid. Yield 63%; Py 1,5308 di 1,4246. 6.75; Found,%: S 15.6; N CI 52.0.

The conditions for carrying out the synthesis and initial purification are similar to example 2. Distillation of unreacted tetrachlorononane is carried out in vacuum (5 mm Hg) in a stream of nitrogen at a temperature of 170 ° C as an azeotrope with ethylene glycol. Purification of the product was carried out on a column of silica gel as in Example 1. The target product was a viscous liquid. Yield 51%; p 1.6265; d 1.4203. Found,%: S 11.0; N 4,6; CI 37.0.
