摘要:
The proposed method of obtaining a physically stable crystalline η-modification of para-aminobenzene sulphanilamide involves cooling a solution of para-aminobenzene sulphanilamide in water, an organic solvent, or a mixture of the two with the aid of a cooling agent at a rate of at least 2 °C/min until the solution is fully crystallized, the crystals thus formed then being removed and dried.
