after 40ml and 40ml of 0.1mol/L hydrochloric acid

identification test	melting point 163~174 ℃ (decomposition). According to the conventional method of measurement. It is the same as the identification test 1 in "thiobenzyl disulfide (01003). A sample of 30mg was added with 1% hydrochloric acid solution for 7 ml, heated and dissolved in a water bath and then added with 2ml of a mixture of (3+20) hydroxylamine hydrochloride solution and (3+20) sodium hydroxide solution (1:1). After shaking and mixing for 1min, add 0.8ml of hydrochloric acid and 0.5ml of (1+10) ferric chloride solution, and the liquid should be purple.
content analysis	accurately weigh about 105g of sample pre-dried at 0.4 ℃ for 2H, and add methanol.
toxicity	LD50 about 30g/kg (mouse, oral).
