CAS 133-74-4; 4-氯苯胺-2-磺酸; 4-Chloroaniline-2-sulfonic acid

CAS:

133-74-4

分子式:

C6H6ClNO2S

分子量:

207.50

熔点:

>300°C

中文名称:

4-氯苯胺-2-磺酸

2-氨基-5-氯苯磺酸

英文名称:

4-Chloroaniline-2-sulfonic acid

2-Amino-5-chlorobenzene sulfonic acid

2-amino-5-chlorobenzenesulphonic acid

性质描述:

无色针状结晶。320-340℃分解。易溶于热水。加热时变红。

生产方法:

由对氯苯胺经磺化而得：将100%硫酸慢慢滴入对氯苯胺和溶剂二苯砜中，激烈反应生成4-氯苯胺-2-磺酸和水。当水被蒸出后，反应混合物变成亮紫色结晶。在减压下继续加热7h，将熔融物冷却，加热水溶解，滤除溶液中的二苯砜，冷却得白色针状结晶。过滤、水洗、干燥而得成品。收率94%。

用途:

用于有机合成中间体。
