8. Ubani igamaNekali BXI-sodium butyl i-Naphthalene Sulfonate? Kokubili i-sodium butyl naphthalene sulfonatekanye ne-isobutyl sodium sulfonate. Kunezindlela ezimbili zokukhiqiza zezimboni ze-Nekal 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. Izinzile emanzini aqinile, usawoti, i-asidi kanye nesisombululo se-alkaline esibuthakathaka, emvuleni emhlophe ye-caustic soda, engeza amanzi ngemva kokuhlanjululwa kungancibilika kabusha.

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. Izakhiwo zamakhemikhali Impushana emhlophe noma ephuzi. Incibilika emanzini.

Ukusetshenziswa kwezindwangu, ukuphrinta nokudaya, imboni yesikhumba nephepha, kanye nesibulala-zinambuzane, i-ejenti yokumanzisa ukhula, i-ejenti ehlakaza upende ne-inki, i-emulsifier yemboni yenjoloba isebenzisa i-Chemicalbook njengendawo yokungena embonini yokunyathelisa yendwangu nokudaya. Ingasetshenziswa futhi njengesihlanzi, insiza yokudaya, i-disperant, i-ejenti yokumanzisa, isibulala-zinambuzane, isibulala-khula kanye ne-emulsifier embonini yenjoloba yokwenziwa. Sebenzisa njenge-ejenti yokungena kanye ne-ejenti yokumanzisa, ingasetshenziswa ezinqubweni ezehlukene zokuphrinta izindwangu kanye nemboni yokudaya, njenge-enzyme desizing, i-wool carbonization, i-cashmere shrinking, i-chlorination, ukwelashwa kwe-rayon kasilika.CAS:25638-17-9.

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. Umkhiqizo unokungeneka okuhle kakhulu, ukumanzisa, i-emulsification, ukusabalalisa kanye nezakhiwo ezikhipha amagwebu. Ekumelaneni ne-asidi, ukumelana ne-alkali, ukumelana kwamanzi aqinile, ukumelana nosawoti wezinto ezingaphili, ukwengeza inani elincane likasawoti kungakhuphula kakhulu ukungena. Isetshenziswa kakhulu ezinqubweni ezehlukene zemboni yokuphrinta yendwangu kanye nokudaya, ikakhulukazi esetshenziswa njenge-ejenti yokungena kanye ne-ejenti yokumanzisa, futhi ingasetshenziswa njenge-detergent, i-dayi aid, i-disperant, i-insecticide kanye ne-herbicide, njll. Indlela yokukhiqiza I-naphthalene ecwengiwe nge-butanol, i-sulfuric acid nge-sulfonation. ukujiya.

Ukusetshenziswa kwempahla eluhlaza (kg/t) I-naphthalene ecwengekile 300 n-butanol 300 sec-octanol 45 I-Fuming sulfuric acid 840 450 sulfate caustic soda 190 impushana ethule 100 Indlela yokukhiqiza Chaza i-naphthalene 426 izingxenye ezingxenyeni ezingu-478 ze-sulfuric 0 i-concentric ye-n-butter engu-1 inyakazisa, bese wengeza fuming sulfuric acid 320 izingxenye. 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.
