This invention relates to a process for the sulphonation of benzene. As is well known, production of benzene sulphonic acid by the sulphonation of benzene is an important step in a commercial method for the manufacture of phenol. This sulphonation may be accomplished by causing benzene in......
Although considerable quantities of the simple monohydric phenols are isolated from coal tar (p. 15), supplies of phenol (and also the cresols) have to be supplemented by synthetic procedures. An important method of manufacture of phenol starts frombenzenesulphonic acid(see below). Another involve...

This is the preferred method of synthesis of picric acid since direct nitration of phenol gives only poor yields due to simultaneous oxidation. Prior introduction of the sulphonic acid group deactivates the system and reduces this oxidative loss. The formation of styphnic acid from resorcinol may ...
