| abstract | Quaternary salts of dialkylaminophenyl esters of alkyl-or aralkylcarbamic acids are obtained by allowing dialkyl sulphates to react with the said esters in organic solvent, followed, if desired, by conversion into the less soluble quaternary ferricyanide or p-toluenesulphonate, or similar salts by interaction with a solution of the sodium or potassium salt of the required acid. According to examples, (1) the quaternary salts of m-dimethylaminophenol methylcarbamic, ethylcarbamic, dimethylcarbamic, benzylcarbamic, and diethylcarbamic esters, m-diethylaminophenol methylcarbamic ester, and m-dimethylaminophenyl piperidyl urethane are obtained by the action of dimethyl sulphate on these compounds, in various solvents; (2) a quaternary ferricyanide is obtained by the action of potassium ferricyanide on the quaternary sulphate of m-diethylaminophenol methyl carbamic ester; (3) m-trimethyl phenylammonium-p-toluenesulphonate is obtained by the action of sodium p-toluenesulphonate on the corresponding methylsulphate. m-Dialkylaminophenol alkyl and aralkylcarbamic esters are obtained by the action of alkyl- or aralkylamines on the corresponding chlorocarbonates of the m-dialkylaminophenols. |
