Nekali BX, i-sodium butylnaphthalene sulfonate, inamafomula angahambisani kakhulu. Kukhona i-sodium butyl naphthalene sulfonate ne-isobutyl naphthalene sulfonate. Kunezindlela ezimbili zokukhiqiza zezimboni zeNekali BX:
(1) I-Naphthalene kanye nesisindo esifanayo se-sulfuric acid sulfonation, ukwakheka kwe-α -naphthalene sulfonic acid, ngaphansi kokuvuselela okunamandla ngesikhathi esifanayo enezela i-sulfuric acid egxilile kanye ne-n-butanol, ngemva kokuhlukana, ukungathathi hlangothi, ukuhwamuka.
② I-Naphthalene yayixutshwe ne-n-butanol, futhi i-sulfuric acid egxilile yengezwa. Ngemuva kokungathathi hlangothi nokomisa, umkhiqizo oqediwe watholwa. Lo mkhiqizo uyimpushana emhlophe futhi ekhanyayo ephuzi, encibilika emanzini. Iyazinzile emanzini aqinile, usawoti, i-asidi kanye nesisombululo se-alkaline esibuthakathaka, kanye nemvula emhlophe ku-cocentrated caustic soda. Ingancibilika futhi ngemva kokuhlanjululwa ngamanzi. Umkhiqizo uwuhlobo lwe-anion, okuqukethwe kwamanzi akukho ngaphezu kwe-2%, okuqukethwe kwe-iron akukhona ngaphezu kwe-0.01%, inani le-pH le-1% isixazululo samanzi 7 ~ 8.5. Ngokungeziwe ekungeneni okuqinile, iphinde ibe ne-emulsification, i-diffusion kanye nezindawo ezikhihliza amagwebu, ikhono lokuhlanza eliphansi, kanye nokumiswa kabi kothuli.
Lo mkhiqizo ungasetshenziswa kabanzi njengendawo yokungena ezinqubweni zokukhuhla, ukuhlanza nokudaya. Ingasetshenziswa futhi njenge-cosolvent yodayi, umsizi wokudaya we-asidi woboya boboya, umsizi wokudaya woboya obudaywe bedayi, umsizi wokudaya wendwangu ehlanganisiwe ye-polyamide, umsizi wokudaya wendwangu ehlanganisiwe ye-polyester / ikotini ehlanganisiwe yokudaya.
sebenzisa
1, esetshenziswa njenge-ejenti engena embonini yokuphrinta yendwangu nokudaya. Ingasetshenziswa futhi njengesihlanzi, insiza yokudaya, i-disperant, i-ejenti yokumanzisa, isibulala-zinambuzane, isibulala-khula kanye ne-emulsifier embonini yenjoloba yokwenziwa.
2. Njenge-ejenti yokungena nokumanzisa, ingasetshenziswa ezinqubweni ezihlukahlukene zokunyathelisa izindwangu kanye nemboni yokudaya, njenge-enzyme desizing, i-wool carbonization, i-cashmere shrinking, i-chlorination, i-rayon silk processing. Ingasetshenziswa futhi njenge-ejenti yokumanzisa embonini ye-papermaking kanye ne-lake. Ukwengeza isixazululo esingu-10% se-BX esingene ku-organic pigment kunenzuzo ekushintsheni kokunamathisela kombala. Isetshenziswa njenge-emulsifier lapho kulungiswa i-pulp yenjoloba.
I-3, umkhiqizo unokungeneka okuhle kakhulu, ukumanzisa, i-emulsification, ukusabalalisa kanye nezakhiwo ezigwebu. Ekumelaneni ne-asidi, ukumelana ne-alkali, ukumelana kwamanzi aqinile, ukumelana nosawoti wezinto ezingaphili, ukwengeza inani elincane likasawoti kungakhuphula kakhulu ukungena. Isetshenziswa kabanzi ezinqubweni ezehlukene zokuphrinta izindwangu kanye nemboni yokudaya, ikakhulukazi esetshenziswa njenge-ejenti yokungena kanye ne-ejenti yokumanzisa, futhi ingasetshenziswa njenge-detergent, i-dayi aid, i-disperant, i-insecticide kanye ne-herbicide, njll.
Izindlela zokukhiqiza
1, i-naphthalene ne-butanol, i-sulfuric acid nge-sulfonation condensation. Ukusetshenziswa kwempahla eluhlaza (kg/t) naphthalene 300 n-butanol 300 octanol 45 intuthu ye-sulfuric acid 840 sulfuric acid 450 caustic soda 190 no powder 100
2. Chaza izingxenye ezingu-426 ze-naphthalene ezingxenyeni ezingu-478 ze-n-butanol, engeza izingxenye ezingu-1 060 ze-concentrate sulfuric acid bese wengeza izingxenye 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.
