실험 절차

A mixture of 98.8 g (0.411 mol) of sodium sulfide, 5.0 g of tetrabutylammonium hydrogen sulfate and 110 ml of water are stirred in a reaction vessel equipped with a stirrer, thermometer and heatable dropping funnel, until a solution is obtained. 107.2 g of melted 2,6-dichlorobenzyl chloride are added with vigorous stirring over a period of 25 minutes at such a rate that the inside temperature does not exceed 55° C. The reaction mixture is worked up as in Example 9a) to give 77.6 g (80% of theory) of bis(2,6-dichlorobenzyl) sulfide in the form of white crystals of melting point 128°-130° C.
