실험 절차

A flask containing 300 ml dry dimethyl formamide was cooled in an ice/salt bath to 3° C. Thionyl chloride (250 ml) was added dropwise with stirring over a period of 2 hrs. Sodium styrene p-sulphonate (200 g}was added in aliquots over a further 1 hour. The reaction mixture was allowed to stand for 24 hours at room temperature. The solution was poured onto ice and extracted with toluene (1000 ml). The extract was neutralised with sodium carbonate, washed with water, dried over magnesium sulphate and the solvent removed by evaporation under vacuum at 30° C. Finally the purified styrene p-sulphonyl chloride was filtered and stored at 5° C. in the dark.
