8. Lebitso la mangNekal BXSodium butyl Naphthalene Sulfonate? Ka bobeli sodium butyl naphthalene sulfonatele isobutyl sodium sulfonate. Ho na le mekhoa e 'meli ea tlhahiso ea indasteri ea Nekal BX:

(1) Naphthalene le boima bo tšoanang ba sulfuric acid sulfonation, ho thehoa ha α -naphthalene sulfonic acid, tlas'a tšusumetso e matla ka nako e le 'ngoe ho eketsa concentrated sulfuric acid le n-butanol, ka mor'a ho arohana, ho se nke lehlakore, ho fetoha mouoane.

② Naphthalene e ne e kopantsoe le n-butanol, 'me e kenyelelitsoe sulfuric acid. Ka mor'a ho se nke lehlakore le ho omisa, sehlahisoa se phethiloeng se ile sa fumanoa. Sehlahisoa sena ke phofo e tšoeu le e bobebe e mosehla, e qhibilihang ka metsing. E tsitsitseng metsing a thata, letsoai, asiti le tharollo e fokolang ea alkaline, ka har'a metsi a mangata a caustic soda e tšoeu, eketsa metsi ka mor'a hore dilution e ka boela ea qhibiliha.

Sehlahisoa ke mofuta oa anion, metsi a metsi ha a fetang 2%, tšepe ea tšepe ha e fete 0.01%, pH ea bohlokoa ea 1% ea tharollo ea metsi 7 ~ 8.5. Ntle le ho kenella ka matla, e boetse e na le emulsification, diffusion le ho phophoma, bokhoni bo bobe ba ho hloekisa, le ho emisoa ha lerōle hampe. Sehlahisoa sena se ka sebelisoa haholo e le se kenellang lits'ebetsong tsa ho hloeka, ho soeufatsa le ho daea. E ka sebelisoa hape e le cosolvent ea dae, mothusi oa dae ea dae ea boea, mothusi oa ho daea oa boea ba dae, mothusi oa ho daea oa polyamide, mothusi oa ho daea oa dae / k'hothone e kopantsoeng ea ho daea. Lintho tsa lik'hemik'hale: phofo e tšoeu kapa e mosehla. E qhibilihang ka metsing.

Ts'ebeliso ea masela, khatiso le ho daea, indasteri ea letlalo le pampiri, hammoho le chefo e bolaeang likokoanyana, sebolaea-lehola se kolobisang, pente le mochini o qhalakanyang enke, indasteri ea rabara e emulsifier e sebelisa Chemicalbook joalo ka e kenang indastering ea khatiso ea masela le ho daea. E ka boela ea sebelisoa e le sesepa, thuso ea dae, dispersant, metsi, sebolaea likokoanyana, herbicide le emulsifier indastering ea rabara ea maiketsetso. E sebelisoa e le moemeli oa ho koloba le ho koloba, e ka sebelisoa lits'ebetsong tse fapaneng tsa indasteri ea khatiso ea masela le ho daea, joalo ka enzyme deizing, wool carbonization, cashmere shrinking, chlorination, rayon silika kalafo.CAS:25638-17-9.

E ka boela ea sebelisoa e le moemeli oa ho kolobisa ho etsa pampiri le indastering ea letša. Ho eketsa 10% tharollo ea BX e kenang ka har'a pigment ea tlhaho ho molemo ho fetola peista ea mebala. E sebelisoa e le emulsifier ha ho etsoa makhasi a rabara. Sehlahisoa se na le matla a ho kenella, ho kolobisa, emulsification, diffusion le thepa ea ho foaming. Ka ho hanyetsa acid, khanyetso ea alkali, ho hanyetsa metsi a thata, ho hanyetsa letsoai, ho eketsa letsoai le lenyenyane ho ka eketsa ho kenella haholo. E sebelisoa haholo lits'ebetsong tse fapaneng tsa indasteri ea khatiso ea masela le ho daea, haholo-holo e sebelisoang e le sesebelisoa sa ho kolobisa le ho kolobisa, hape e ka sebelisoa e le sesepa, thuso ea dae, dispersant, chefo e bolaeang likokoanyana le herbicide, joalo-joalo Mokhoa oa tlhahiso o hloekisitsoeng naphthalene ka butanol, sulfuric acid ka sulfonation condensation.

Tšebeliso ea lintho tse tala (kg/t) Naphthalene e hloekisitsoeng 300 n-butanol 300 sec-octanol 45 Fuming sulfuric acid 840 450 sulfate caustic soda 190 phofshoana e khutsitseng 100 Mokhoa oa tlhahiso Qhala naphthalene 426 likarolo ka 478 n-sulfuric 0 likarolo tse 478 sulfuric 0 underbure susumetsang maikutlo, ka nako eo eketsa fuming sulfuric acid 320 likarolo. Gabi e ne e futhumetse butle ho 50-55 ℃ mme e bolokoa lihora tse 6. Ka mor'a ho ema, acid e ka tlaase e lokolloa. Tharollo e ka holimo ea karabelo ha e na lehlakore ka alkali, ebe e soeufalitsoe ka sodium hypochlorite, sedimentation, filtration, fafatsa le ho omisa ho fumana sehlahisoa se felileng.
