制备方法与用途

应用

3,4,6-三氯哒嗪,熔点为57-59℃,是多种药物合成的重要中间体,也是液晶工业中的关键原料。

制备

第一步:制备氯代顺酐

在1000L反应釜中加入50千克顺丁烯二酸酐,并添加75千克水。开启搅拌并通入蒸汽升温至60-80℃,溶后将100千克液氯输入密封的缓冲管内,再缓缓通入反应釜内。通氯结束后,保温搅拌40分钟后,开启蒸汽进行减压浓缩0.5小时,冷却结晶至10℃后离心干燥,得到氯代顺酐约40千克,收率为80%,呈灰白色。

第二步:制备4-氯二羟基哒嗪

在另一1000L反应釜中加入132千克40%水合肼和50千克水。开启冷却系统使釜内温度降至20℃以下,开始滴加30%盐酸至pH值6.5后,加入95千克氯代顺酐,并升温至90-95℃保温1.5小时。冷却结晶至5℃后出料,滤饼用冰水洗涤至pH值5-6,干燥得4-氯二羟基哒嗪约100千克,收率为105.263%,色泽纯净,呈白色。

第三步:制备3,4,6-三氯哒嗪

将100千克4-氯二羟基哒嗪投入500L反应釜内,抽入272千克氧氯化磷。开启搅拌并缓缓滴加2千克α-甲基吡啶作为催化剂。当出现高潮回流后,升温至90-95℃保温1.5小时得氯化油。将所得氯化油抽入高位槽中与20%氨水并立滴入冰解釜内,并开启搅拌以pH值7为终点进行滴加。随后放入结晶槽自然冷却结成黑色固体结晶,产出3,4,6-三氯哒嗪粗品约105千克,收率为105%,以4-氯二羟基哒嗪计。将此粗品投入蒸馏釜中,采用升华法减压蒸馏得精品3,4,6-三氯哒嗪101.5千克,含量为99.3%。

最终总收率(以顺丁烯二酸酐计)约为101.5%。
