Sodium butyl naphthalene sulfonate:

1. Sungunulani magawo 426 a naphthalene mu 478 mbali za n-butanol, onjezerani 1 060 magawo a sulfuric acid ndi 320 mbali za fuming sulfuric acid pansi pa chipwirikiti. Gabi adatenthedwa pang'onopang'ono mpaka 50-55 ℃ ndikusungidwa kwa 6h. Pambuyo pa kuyima, asidi wapansi amamasulidwa. The chapamwamba anachita njira ndi neutralized ndi mchere, ndiyeno bleached ndi sodium hypochlorite, sedimentation, kusefera, kupopera mbewu mankhwalawa ndi kuyanika kupeza yomalizidwa mankhwala.

2. Kuchokera ku naphthalene ndi butanol, sulfuric acid ndi sulfonation reaction yokonzedwa:

25638-17-9 kukonzekera

320kg butanol ndi 60kg sec-octanol adawonjezedwa mumphika wamachitidwe, kusonkhezeredwa ndi kuzizira, ndipo 276kg naphthalene anawonjezedwa. 1232kg sulfuric acid (98% sulfuric acid 470kg ndi 20% fuming sulfuric acid 762kg) anawonjezedwa mkati 3h pa 40 ~ 45 ℃. Mukawonjezera, imangotentha mpaka 50 ~ 55 ℃ mkati mwa 1.5h ndikugwira pa 55 ~ 58 ℃ kwa 5h. Tiyeni tiyime kwa 3h ndikulekanitsa zinyalala asidi m'munsi wosanjikiza. Onjezani 500kg ya madzi kuti muchepetse, ozizira mpaka 40 ~ 50 ℃, ikani zinthuzo mumtsuko wa neutralization, onjezerani 30% alkali yamadzimadzi kuti muchepetse nthawi yomweyo, kutentha kwa neutralization sikudutsa 60 ℃, kulamulira pH mtengo ndi 7 ~ 8. Zinthu zamadzimadzi zouma, pansi, kuwonjezera sodium sulphate pogaya, ndipo yokhazikika yolowera BX1100kg imapezeka.
