I-sodium butyl naphthalene sulfonate:

1. Chaza izingxenye ezingu-426 ze-naphthalene ezingxenyeni ezingu-478 ze-n-butanol, engeza izingxenye ezingu-1 060 ze-sulfuric acid egxilile kanye nezingxenye ezingu-320 ze-sulfuric acid evuthayo ngaphansi kokuyaluza. I-Gabi yayishiselwa kancane ibe ngu-50-55 ℃ futhi igcinwe amahora angu-6. Ngemuva kokuma, i-asidi engaphansi iyakhululwa. Isixazululo esingaphezulu sokusabela sincishiswa nge-alkali, bese sixutshwa nge-sodium hypochlorite, i-sedimentation, ukuhlunga, ukufutha nokomisa ukuze uthole umkhiqizo ophelile.

2. Kusuka ku-naphthalene ne-butanol, i-sulfuric acid ngokusabela kwe-sulfonation elungiselelwe:

25638-17-9 ukulungiswa

I-butanol engu-320kg kanye ne-60kg sec-octanol yengezwe ebhodweni lokusabela, yanyakaziswa futhi yapholiswa, kwaphinde kwengezwa i-naphthalene engu-276kg. 1232kg sulfuric acid (98% sulfuric acid 470kg kanye 20% fuming sulfuric acid 762kg) yengezwe phakathi 3h at 40 ~ 45 ℃. Ngemva kokungeza, izofudumeza ngokuzenzakalelayo kufika ku-50 ~ 55℃ phakathi kuka-1.5h futhi ibambe ku-55 ~ 58℃ amahora angu-5. Vumela ume amahora angu-3 bese uhlukanisa i-asidi edoti engxenyeni engezansi. Faka u-500kg wamanzi ukuze uhlanjululwe, upholile ku-40 ~ 50 ℃, faka into ebhakedeni le-neutralization, engeza u-30% we-alkali ewuketshezi ukuze ungathathi hlangothi ngasikhathi sinye, izinga lokushisa lokungathathi hlangothi alidluli ku-60 ℃, lawula inani le-pH liyi-7 ~ 8. I-liquid yezinto ezibonakalayo yomile, iphansi, yengeza i-sodium sulfate yokugaya, futhi i-penetrant standardized BX1100kg iyatholakala.
