    • The present disclosure provides a process for producing taurine, includes: adjusting a PH value of a sodium taurate solution by a S4+ compound; introducing ethylene oxide into the sodium taurate solution to produce sodium hydroxyethyl sulfonate; separating crude taurine before or after introducing the ethylene oxide to the solution; and adding ammonia to the sodium hydroxyethyl sulfonate reaction solution to be reacted with the reaction solution to reproduce sodium taurate. The process for producing taurine of the present disclosure makes use of the balances of the sodium bases in the system, recycles the mother liquor until the sodium taurate is reproduced out of the reactions in the mother liquor, and thus is capable of allowing taurine to be synthesized and extracted.
    • 本公开内容提供了生产牛磺酸的方法,包括:通过S4 +化合物调节牛磺酸钠溶液的PH值; 将环氧乙烷引入到牛磺酸钠溶液中以产生羟乙基磺酸钠; 在将环氧乙烷引入溶液之前或之后分离粗牛磺酸; 并向羟乙基磺酸钠反应溶液中加入氨与反应溶液反应以再生牛磺酸钠。 本公开的生产牛磺酸的方法利用系统中钠碱的平衡,循环使用母液,直到牛奶酸钠从母液中的反应中再现出来,因此能够使牛磺酸成为 合成和提取。
