过氧化氢氧化法制偶氮二甲酰胺工艺的研究

Study of hydrogen peroxide oxidation azo two formamide process

采用过氧化氢(含量50%以上)为氧化剂,以溴化钠为主催化剂、铁基物质为助催化剂氧化联二脲制偶氮二甲酰胺产品,工艺操作简单,且反应母液循环套用,减少"三废"排放,达到清洁文明生产效果。

Using hydrogen peroxide as oxidizing agent,sodium bromide and iron based as catalyst, to oxidative coupling of two urea preparation azo two formamide. The process simple and mother liquor circulated, The three waste was reduced and achieved the clean production effect.
