Introduction
Aminobenzene sulfonic acid, also known as sulfamine phenol, is an organic compound. The following is an introduction to the properties, uses, preparation methods and safety information of p-aminobenzene sulfonic acid:
Quality:
Aminobenzenesulfonic acid is a white crystalline powder that is odorless and soluble in water and ethanol.
Uses: It can also be used in the synthesis of certain dyes and chemical agents.
Method:
Aminobenzenesulfonic acid can be obtained by the reaction of benzenesulfonyl chloride and aniline. First, aniline and alkali are condensed to form m-aminobenzene sulfonic acid, and then aminobenzene sulfonic acid is obtained by acylation reaction.
Safety Information:
Apart from its irritating effects on the eyes, skin, and respiratory tract, aminobenzene sulfonic acid has not been clearly reported to be toxic or dangerous. When using or handling aminobenzene sulfonic acid, maintain good ventilation, avoid contact with eyes and skin, and wear protective equipment if necessary. If accidentally ingested or touched, seek medical attention immediately. When storing and preserving, it should be kept in a dry, cool place, away from fire and other flammable items.
