실험 절차
To a solution of 35.4g (0.2 mole) 4-phenyl urazole in 200 ml water was added a solution of 16g (0.4 mole) sodium hydroxide in 20 ml water. A mixture of 74.4g (0.4 mole)trichloromethylsulfenyl chloride and 3g of an emulsifier solution (EXEM 25, consisting of a mixture of alkyl benzene sulfonate and ethoxylated vegetable oil) in 50 ml water was added dropwise to the above basic solution while keeping the reaction mixture at 0° C. The reactants were mixed so that the reaction mixture was kept at a pH greater than 7. The precipitate that formed was filtered and the filter cake was washed with water. After drying and recrystallizing from benzene there was obtained 4-phenyl-1,2-bis-(trichloromethylthio)urazole having a melting point of 175° C.
