Iindaba

Isodium butyl naphthalene sulfonate:

1. Dissolve 426 iinxalenye ze-naphthalene kwiindawo ze-478 ze-n-butanol, yongeza i-1 060 ye-concentrated sulfuric acid kunye ne-320 ye-fuming sulfuric acid phantsi kokuphazamiseka. I-Gabi yayifudunyezwa kancinane ukuya kwi-50-55 ℃ kwaye igcinwe i-6h. Emva kokuma, i-asidi engaphantsi ikhutshwa. Isisombululo esiphezulu sokusabela singathathi hlangothi ngealkali, kwaye emva koko sixutywe nge-sodium hypochlorite, i-sedimentation, i-filtration, ukutshiza kunye nokomisa ukufumana imveliso egqityiweyo.

2. Ukusuka kwi-naphthalene kunye ne-butanol, i-asidi ye-sulfuric ngokuphendula kwe-sulfonation elungiselelwe:

25638-17-9 ukulungiselela

I-320kg ye-butanol kunye ne-60kg sec-octanol zongezwa kwi-reaction pot, yaxutywa kwaye yapholiswa, kwaye i-276kg ye-naphthalene yongezwa. I-1232kg sulfuric acid (98% sulfuric acid 470kg kunye ne-20% evuthayo sulfuric acid 762kg) yongezwa ngaphakathi kwe-3h kwi-40 ~ 45 ℃. Emva kokongeza, iya kutshisa ngokuzenzekelayo ukuya kuthi ga kwi-50 ~ 55℃ ngaphakathi kwe-1.5h kwaye ibambe kwi-55 ~ 58℃ ye-5h. Makhe ume i-3h kwaye uhlukanise i-asidi yenkunkuma kwinqanaba eliphantsi. Yongeza i-500kg yamanzi ukuze idilution, ipholile ukuya kwi-40 ~ 50 ℃, faka izinto kwi-emele yokungathathi hlangothi, yongeza i-30% ye-alkali yolwelo ukwenzela ukungathathi hlangothi kwangaxeshanye, ubushushu be-neutralization alidluli kwi-60 ℃, lawula ixabiso le-pH yi-7 ~ 8. I-liquid yezinto eziphathekayo yomile, iphantsi, yongeza i-sodium sulfate yokugaya, kunye ne-standard penetrant BX1100kg ifunyenwe.
