摘要：
A method is described for the quaternization of nitrogen-containing heterocyclic azo dyes using dimethyl sulphate and arylsulphonic acid methyl esters as alkylation agents in a two-phase liquid medium. The method is distinguished by fully competed quaternization at high reaction rates and moderate reaction temperatures.
