Xov xwm

Sodium butyl naphthalene sulfonate:

1. Dissolve 426 qhov chaw ntawm naphthalene nyob rau hauv 478 qhov chaw ntawm n-butanol, ntxiv 1 060 qhov chaw ntawm concentrated sulfuric acid thiab 320 qhov chaw ntawm fuming sulfuric acid nyob rau hauv agitation. Gabi tau maj mam rhuab mus rau 50-55 ℃ thiab khaws cia rau 6h. Tom qab sawv ntsug, lub hauv paus acid raug tso tawm. Cov tshuaj tiv thaiv sab saud yog nruab nrab nrog alkali, thiab tom qab ntawd bleached nrog sodium hypochlorite, sedimentation, pom, txau thiab ziab kom tau cov khoom tiav.

2. Los ntawm naphthalene thiab butanol, sulfuric acid los ntawm sulfonation cov tshuaj tiv thaiv npaj:

25638-17-9 kev

320kg butanol thiab 60kg sec-octanol tau ntxiv rau lub lauj kaub tshuaj tiv thaiv, nplawm thiab txias, thiab 276kg naphthalene tau ntxiv. 1232kg sulfuric acid (98% sulfuric acid 470kg thiab 20% fuming sulfuric acid 762kg) tau ntxiv hauv 3h ntawm 40 ~ 45 ℃. Tom qab ntxiv, nws yuav cia li kub txog 50 ~ 55 ℃ nyob rau hauv 1.5h thiab tuav ntawm 55 ~ 58 ℃ rau 5h. Cia sawv ntsug rau 3h thiab cais cov kua qaub pov tseg hauv cov txheej qis. Ntxiv 500kg dej rau dilution, txias rau 40 ~ 50 ℃, muab cov khoom tso rau hauv lub thoob nruab nrab, ntxiv 30% kua alkali rau neutralization tib lub sijhawm, qhov nruab nrab kub tsis tshaj 60 ℃, tswj pH tus nqi yog 7 ~ 8. Cov khoom siv ua kua qhuav, hauv av, ntxiv sodium sulfate rau kev sib tsoo, thiab tau txais cov txheej txheem penetrant BX1100kg.
