stability

Easy to decompose in alkaline medium.

The process is carried out according to the following steps: (1) synthesis of α-chlorinated acetoacetanilide (chlorination) Add acetoacetanilide and toluene to the reactor, stir at about 20℃ and add sulfuryl chloride, control the reaction temperature at 25-30℃, after half an hour, continue to hold the temperature for 2.5h, namely, toluene suspension of α-chlorinated acetoacetanilide. (2) Synthesis of seed mixture (condensation) : Add the toluene suspension obtained in the first step to thiourea and water, heat up to reflux, reaction for half an hour. After the reaction, the Chemicalbook was stratified with toluene layer on the upper layer, which could be continued to be used in circulation, and the lower layer was the water solution of seed mixture hydrochloride. Separate the water layer and dilute it with water. After stirring, neutralize it with ammonia water to pH8, and filter the precipitation generated by washing it with water until it is nearly neutral. Then, the white powder product is dried and the content is about 96%. The yield of p-acetoacetanilide is about 8%. Raw material consumption quota: acetoacetanilide (>98) 880kg/t, sulfuryl chloride (100%) 700kg/t, thiourea (>95%) 410kg/t, ammonia water (25%) 520kg/t.
