Process for producing J acid through mother liquor recycling and pressurized alkali fusion
The invention belongs to the field of J acid preparation, and relates to a process for producing J acid through mother liquor recycling and pressurized alkali fusion; wherein tobias acid is sulfonated and then diluted with water instead of washing water containing sodium sulfate, it is avoided that sodium sulfate is contained in dilute sulfuric acid of amino J acid mother liquor, the amino J acid mother liquor can be used for producing magnesium sulfate, liquid-phase pressurized alkali fusion enables the reaction to be more thorough; and the material coking is avoided, the yield is improved, and the unit consumption of tobias acid is reduced by over 150kg compared with that of the traditional process. The strip liquor obtained by combining and extracting the amino J acid mother liquor is used for producing the water reducing agent, so that the materials are fully utilized.
本发明属于J酸制备领域，涉及一种母液循环利用和加压碱熔生产J酸的工艺，其吐氏酸磺化后用水稀释而不用含硫酸钠的洗水稀释，避免氨基J酸母液的稀硫酸中含硫酸钠，使氨基J酸母液可用来生产硫酸镁，液相加压碱熔使其反应更彻底，还避免了物料焦化，提高了收率，吐氏酸单耗比传统工艺下降150kg以上。氨基J酸母液，J酸母液经络合萃取后的反萃液用来生产减水剂，使物料得到充分利用。
