Synthesis method
Tau los ntawm reactingp-toluenesulfonamidenrog ammonia dej.
Cov txheej txheem thev naus laus zis:
Ua ntej, txhaj cov dej khov uas tsim nyog rau hauv lub lauj kaub amination, thiab tom qab ntawd muab tso rau hauv lub lauj kaub raws li qhov sib piv (p-toluenesulfonyl chloride: ntshiab ammonia=1: 0.2). Pib tus neeg sawv cev nplawm thiab siv cov kua dej txias hauv lub tsho ntawm lub lauj kaub amination los tswj qhov kub hauv lub lauj kaub rau 70 ° C (cov tshuaj tiv thaiv yog exothermic),;
Tom qab ntawd txo qhov kub kom txog 30 ° C thiab tawm mus. Amino acid ntsev yog lim nyob rau hauv ib lub thoob lim dej, ntxuav nrog dej sov, thiab ces qhuav kom qhuav crude p-toluenesulfonic acid amide hmoov.
Nws muaj ib tug me me ntawm oily tshuaj, uas yog byproducts ntawm thawj cov ntaub ntawv. Lub hom phiaj ua kom huv tuaj yeem ua tiav los ntawm kev siv cov yam ntxwv ntawm ammonia amine dissolution hauv sodium hydroxide tov thiab activated carbon decolorization.
Cov khoom siv zoo piv yog crude amine: 30% sodium hydroxide kua alkali: dej =100: 45: 1300; Crude amine: activated carbon=100: (2.5-3.5).
Muab dej thiab caustic soda rau hauv lub lauj kaub ua kom huv raws li cov qauv, qhib lub tsho chav dej, thiab cua sov rau 70℃C;
Tom qab ntawd ntxiv cov para amine precursor rau cov mis, pib lub tov khoom, thiab thaum lub para amine precursor yog yaj tag, ntxiv cov activated carbon nyob rau hauv cov mis ob peb zaug, ntxiv stirring rau 0.5 teev, ncuav cov kua rau hauv ib lub thoob ntawv lim, tshav kub thiab lim, ntxuav nrog dej kub, thiab ces nqus qhuav;
Cov kua lim dej yog muab tso rau hauv lub lauj kaub ua kom zoo, nruab nrab nrog hydrochloric acid rau pH =2-3, txias rau li 30-35 ° C, thiab cov kua pub yog muab tso rau hauv lub thoob lim dej kom pom, ntxuav nrog dej kom txog thaum nruab nrab;
Tom qab ntawd hloov mus rau lub centrifuge kom qhuav, ua rau cov khoom tiav nrog cov ntsiab lus noo ntawm 10%. Yog xav tau kom qhuav, nws yuav tsum raug xa mus rau lub tshuab ziab khaub ncaws kom qhuav kom tau cov khoom tiav nrog cov dej noo ntawm 1%.
Ntxiv p-toluenesulfonyl chloride thiab ntshiab ammonia rau cov dej khov dej hauv ib ntus, tswj qhov sib piv ntawm p-toluenesulfonyl chloride rau ntshiab ammonia rau 1:0.2, do cov tshuaj tiv thaiv, txias thiab tswj qhov kub ntawm 70℃C.
Tom qab cov tshuaj tiv thaiv, cov khoom nyoos yog txias, lim, thiab ntxuav, thiab thaum kawg cov khoom tiav tau txais los ntawm alkaline ntxuav, decolorization, dej ntxuav, neutralization, pom, dej ntxuav, thiab ziab.
