Nekal BX, i-sodium butylnaphthalene sulfonate, ineefomula ezingahambelani kakhulu. Kukho i-sodium butyl naphthalene sulfonate kunye ne-isobutyl naphthalene sulfonate. Kukho iindlela ezimbini zemveliso yemveliso yeNekal BX:
(1) I-Naphthalene kunye nobunzima obufanayo be-sulfuric acid sulfonation, ukubunjwa kwe-α -naphthalene sulfonic acid, phantsi kokuvuselela okukhulu ngexesha elifanayo ukongeza i-sulfuric acid kunye ne-n-butanol, emva kokuhlukana, ukungathathi hlangothi, ukukhuphuka.
② I-Naphthalene ixutywe kunye ne-n-butanol, kwaye i-asidi ye-sulfuric egxininisiweyo yongezwa. Emva kokungathathi hlangothi kunye nokomisa, imveliso egqityiweyo yafunyanwa. Le mveliso imhlophe kunye nomgubo ophuzi okhanyayo, onyibilikayo emanzini. Izinzile kumanzi anzima, ityuwa, i-asidi kunye nesisombululo esibuthakathaka se-alkaline, kunye ne-white precipitate kwi-concentrated caustic soda. Inokuchithwa kwakhona emva kokuhlanjululwa ngamanzi. Imveliso luhlobo lwe-anion, umxholo wamanzi awukho ngaphezu kwe-2%, umxholo wesinyithi awukho ngaphezu kwe-0.01%, ixabiso le-pH le-1% isisombululo samanzi 7 ~ 8.5. Ukongeza kwi-permeability eyomeleleyo, ikwane-emulsification, i-diffusion kunye neempawu zogwebu, ukungakwazi ukucoca okungalunganga, kunye nokumiswa kakubi kothuli.
Le mveliso ingasetyenziswa ngokubanzi njengendawo yokungena ekukhuhleni, kwi-bleaching kunye neenkqubo zokudaya. Isenokusetyenziswa njengedayi ye-cosolvent, i-asidi yedayi yedayi umncedisi wokudaya, umncedisi wokudaya wedayi wedayi, ilaphu elidityanisiweyo le-polyamide umncedisi wokudaya, ukusasaza idayi ye-polyester / umqhaphu odityanisiweyo wokuncedisa ilaphu lokudaya.
sebenzisa
1, esetyenziswa njengearhente yokungena kushicilelo lwelaphu kunye neshishini lokudaya. Isenokusetyenziswa njengesicoci, isincedisi sedayi, i-dispersant, i-ejenti yokumanzisa, isibulali-zinambuzane, imichiza yokutshabalalisa ukhula kunye ne-emulsifier kwishishini lerabha yokwenziwa.
2. Njenge-ejenti yokungena kunye nokumanzisa, inokusetyenziswa kwiinkqubo ezahlukeneyo zoshicilelo lwelaphu kunye neshishini lokudaya, njenge-enzyme desizing, i-carbonization yoboya, i-cashmere shrinking, i-chlorination, i-rayon silk processing. Isenokusetyenziswa njenge-arhente yokumanzisa kwi-papermaking nakwishishini lechibi. Ukongeza i-10% yesisombululo se-BX esingena kwi-organic pigment kunenzuzo ekumodareyitheni kombala. Isetyenziswe njenge-emulsifier ekulungiseleleni i-pulp yerabha.
I-3, imveliso inokugqwesa okugqwesileyo, ukumanzisa, i-emulsification, i-diffusion kunye neempawu zogwebu. Ekuxhathiseni i-asidi, ukuxhathisa kwealkali, ukuxhathisa amanzi anzima, ukuxhathisa ityuwa ye-inorganic, ukongeza inani elincinci letyuwa kunokunyusa kakhulu ukugqithiswa. Isetyenziswa kakhulu kwiinkqubo ezahlukeneyo zoshicilelo lwelaphu kunye nomzi-mveliso wokudaya, ikakhulu osetyenziswa njenge-ejenti yokutyhutyha kunye ne-ejenti yokumanzisa, inokusetyenziswa njenge-detergent, i-dayi yokuncedisa, i-disperant, i-insecticide kunye ne-herbicide, njl.
Iindlela zokuvelisa
I-1, i-naphthalene kunye ne-butanol, i-asidi ye-sulfuric nge-sulfonation condensation. Ukusetyenziswa kwezinto ezikrwada (kg/t) naphthalene 300 n-butanol 300 octanol 45 umsi sulfuric acid 840 sulfuric acid 450 caustic soda 190 akukho powder 100
2. Dissolve 426 iinxalenye ze-naphthalene kwiindawo ze-478 ze-n-butanol, yongeza i-1 060 ye-concentrated sulfuric acid uze udibanise iingxenye ze-320 ze-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.
