性质描述: 淡黄色粉状,熔点317℃(336℃),相对密度1.35-1.64。不溶于水,微溶于乙醇。在逍硫酸中为红光橙色,稀释后呈棕光黄色沉淀;在浓硝酸中为棕色黄色。属双偶氯型不溶性颜料,这类颜料的着色力强,耐溶剂性优良,但耐光性不如单偶氮型颜料。耐溶剂性(对乙醇、二甲苯、丙酮、溶纤素;硝化纤维溶剂)很好,耐热性在150℃稳定,耐碱性(5%Na2CO3)很好,耐酸性(5%HCl中不变)、耐渗化性(水渗性、油渗性、乙醇渗性)优异或很好,耐晒性良好,吸油率37-52%。在浓硫酸中呈艳红色,在稀硫酸中为绿光黄色沉淀。
生产方法: 方法1:由3,3'-二氯联苯胺重氮化后,与乙酰乙酰苯胺进行偶合,而后经过滤、干燥等处理过程而制产品。1.重氮化2.偶合产品要求色光与标准品近似,着色力为标准品100±5(分),水分含量≤2%,吸油量50±5%,水溶性盐含量≤1.5%,耐热性180℃,耐晒性5-6级,耐酸性、耐碱性均为1-2级,水渗性、油渗性均为1-2级,乙醇渗性1级,石蜡渗性2级,细度(通过60筛余物含量)≤5%。原料消耗(kg/t)3,3'-二氯联苯胺(100%) 410乙酰乙酰苯胺(100%) 590盐酸(31%) 930亚硝酸钠(工业) 235纯碱(工业) 495冰醋酸 615活性炭 10太古油 55方法2:由邻硝基氯苯出发,在烧碱溶液介质中用锌粉还原,并缩合为2,2'- 二氯二苯肼。再用盐酸处理。转位成3,3'二氯联苯胺盐酸盐。而后将3,3'-二氯联苯胺重氮化,再与邻-乙酰乙酰甲苯胺进行偶合,而得到产品。1.还原缩合2.转位、盐析3.重氮化、偶合
用途: 主要用于油墨、橡胶、聚乙烯、取乙烯、聚苯乙烯、聚氯乙烯及酚醛、脲醛等塑料的着色,也用于纺织品的涂料印花,还可用于涂料及纸张的着色。该品具有优良的鲜艳度、着色力强,耐晒好,且有较好的透明度和遮盖力,用途广泛。
