    主要研究了由磺胺经重氮化反应合成4-磺酰胺基苯肼盐酸盐，考察了重氮盐还原反应中温度、Na2SO3投料量，对磺酰胺基苯肼成盐时盐酸用量对反应及产率的影响；同时考察了管式反应在4-磺酰胺基苯肼盐酸盐合成中的应用。
    주요연구료유광알경중담화반응합성4-광선알기분정염산염，고찰료중담염환원반응중온도、Na2SO3투료량，대광선알기분정성염시염산용량대반응급산솔적영향；동시고찰료관식반응재4-광선알기분정염산염합성중적응용。
    The synthesis of reducing sulfanilamide via diazotization to 4-sulfonamidophenylhydrazine hydrochloride was dealt with. The effect of the factors on the reaction were discussed, such as the reaction temperature, the amount of sodium sulfite and the hydrochloric acid. The method of pipeline reaction in 4-sulfonamidophenylhydrazine hydrochloride preparing process was also investigated.
