其他信息

  • 方法一:1,2,4-三氯苯的制备以六六六无毒异构体为原料,可采用热分解、碱水分解、石灰乳分解三种方法制得,所得产品中含有少量1,2,3-三氯苯和1,3,5-三氯苯。 此法得到的1,2,4-三氯苯含量最高。 工艺过程为六六六无毒异构体与消石灰(50%~60%)的质量比为1∶0.666,水的用量为消石灰的10倍以上。操作时先取400kg六六六无毒异构体加入脱氯化氢器内,再将消石灰230kg、水3t-同加入配料槽内,搅拌20min后,再用泵送入脱氯化氢器内。通入蒸汽预热至60℃时开始往冷凝器夹层内放入冷水,至90℃时停止直接蒸汽加热,瞬间器内即沸腾。控制蒸汽压力为53.2~66.5kPa,调节冷凝水,使出口水温在50~55℃。三氯苯随水蒸气蒸出,经冷凝器冷凝而进入分液器内。因三氯苯比水重,所以沉于器底。由水上部溢流管流回脱氯化氢器内再利用。反应时间共8h,三氯苯即全部蒸出。然后停止加热,由分液器底部将三氯苯放人大桶即为成品;未反应的残渣由脱氯化氢器下口排入下水道。此法中熔化石灰石需1.3h,脱氯化氢需9.6h,共计约需11h。 另一工艺过程为:水解温度210~215℃,压力1.96MPa,石灰乳过量10%条件下,将甲乙体完全分解为三氯苯,因此产率高,可达94%以上,无明显副反应,避免热解碳化物引起职业病,产品质量高,含1,2,4-三氯苯90%以上,排出废渣少,废液不多,易于综合利用,设备简单,生产强度高,但成本高于热解法,且水解釜腐蚀严重。 烧碱加压水解法 以六六六无毒体为原料,经与烧碱液混合,在加压下水解而得。 此法水解温度180℃,压力0.98MPa,用联苯醚锅炉加热,反应70~80min后得到三氯苯,收率约94%。水解釜腐蚀速度较慢,为高压石灰乳法的11%,可消除职业中毒,解决了环境污染问题。此法流程短,生产稳定,操作方便,工艺可行,但消耗碱,成本高,比石灰乳法产品中1,2,4-三氯苯含量低。 (3)热解法 此法工艺过程简单,设备生产强度大,能回收副产盐酸,成本低,但职业中毒严重。 过去1,2,4-三氯苯主要依靠林丹副产的无效体加工成混合三氯苯,再分馏而得1,2,4-三氯苯。随着对林丹的限制,传统的三氯苯原料日益减少,国外目前工业化方法为二氯苯选择性氯化得到三氯苯混合物,然后采用分子筛吸附
  • 用途二
  • 上游原料:氢氧化钠 --> 氢氧化钙 --> 碳酸钙 --> 1,2,3-三氯苯 --> 1,3,5-三氯苯 --> 脉石中的矿石,填充料,物料
  • 方法二:1.热解法干燥的六六六无毒体在热解釜中加热热即得三氯苯,同时副产大量氯化氢。2.碱解法六六六无毒体与石灰乳共热即得三氯苯,同时副产大量氯化钙液。上述二法所得三氯苯均为1,2,4-三氯苯;1,3,5-三氯苯;1,2,3-三氯苯三种异构体的混合物,以1,2,4-三氯苯为主要组分。石灰乳法生产的三氯苯中,1,2,4-三氯苯含量在75%以上,1,2,3-三氯苯约占20%。
