p-Dimethylaminoazobenzene was praparad by modifying Miihlau's ethod of coupling dimethylamiline with benzenediazonium salt in acidic solution and precipitating the product by means of alkalization. Detailed procedura was worked out. As a result of avoiding decomposition, a higher yield, namaly 80%, was attailied. The product was sufficiently pure for ordinary purposea.
