4-Amino-3-chlorobenzenesulfonic acid synthesis
- Product Name:4-Amino-3-chlorobenzenesulfonic acid
- CAS Number:98-35-1
- Molecular formula:C6H6ClNO3S
- Molecular Weight:207.63
Yield:-
Steps:
5 2-Chloroaniline-4-sulphonic acid
EXAMPLE 5 2-Chloroaniline-4-sulphonic acid Starting from 293.5 g of 2-chloroaniline, 460 ml of o-dichlorobenzene and 225.5 g of monohydrate, the reaction was performed as in Example 4. After 4.3 hours at 200° C., the mixture was cooled, filtered off with suction and dried. The isolated solid weighed 489.3 g and contained 51.1% of 2-chloroaniline-4-sulphonic acid, based on the use of 2-chloroaniline, with a selectivity of 100%.
