Abstract
Inventia se refera la un procedeu de obtinere a acidului 1-naftol-4-sulfonic, prin sulfonarea alfa-naftolului cu acid sulfuric, urmata de purificarea si izolarea produsului finit, prin care, în scopul îmbunatatirii calitatii acidului 1-naftol-4-sulfonic si al micsorarii duratei de reactie la circa 2,5...3h, reactia de sulfonare se realizeaza cu acid sulfuric monohidratat în mediu de tetraclorura de carbon si în prezenta unui agent tensioactiv de suprafata neionic, la temperatura de 65...67 degree C.
