  • 方法二:将尿素溶于2%的水合肼溶液,搅拌,并加入硫酸,使Ph值达到1~2,然后加热使Ph值为2~5,再缓缓加入硫酸,保持Ph值2~5,反应数小时后取样测定终点;反应结束后,过滤去除硫酸铵母液,并用热水洗涤得联二脲。 将联二脲溶于水,加入溴化钠,通入氯气,在30~50℃反应;反应混合物用温水洗至中性,再离心甩干、干燥得成品。每吨产品消耗水合肼(40%)1160kg,尿素1330kg,液氯800kg,烧碱(3

  • 方法三:工业生产发泡剂AC,由水合肼、尿素与硫酸缩合成中间体联二脲,再经氧化而得成品。1.缩合将尿素溶于2%水合肼溶液,加到反应锅。在搅拌下加硫酸使料液pH值达到1-2,加热,使pH值转为2-5,再缓缓加入硫酸,保持pH值2-5反应数小时后,取样测定终点(用0.1N碘溶液滴定含肼量)。缩合成的联二脲,滤出硫酸铵母液后,用热水洗涤,供氧化工序用。2.氧化将联二脲放入反应锅用水溶解,加入溴化钠,通入氯气,反应温度控制在30-50℃,制得的偶氮二甲酰胺先用温水洗至中性,经离心机甩干干燥后,得成品。氧化工序对发泡剂AC的产品质量和生产本影响最大。早期采用硝酸法和铬酸法,由于成本和污染的原因,已趋于淘汰。氯气-溴为氧化剂取代铬盐氧化联二脲生产发泡剂AC的方法,使产品成本降低很多。其他的方法还有:有空气和二氧化氮处理联二脲,收率为84.3%;用电解法生产发泡剂AC;采用过氧化氢氧化联二脲的方法。原料消耗定额:水合肼(40%)1160kg/t、尿素(含氮量≥46%)1330kg/t、液氯800kg/t
