Nekal BX, sodium butylnaphthalene sulfonate, e na le mekhoa e sa lumellaneng haholo. Ho na le sodium butyl naphthalene sulfonate le isobutyl naphthalene sulfonate. Ho na le mekhoa e 'meli ea tlhahiso ea indasteri eaNekal 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 tsitsitse metsing a thata, letsoai, asiti le tharollo e fokolang ea alkaline, le precipitate e tšoeu ka har'a soda le ho feta. E ka qhibiliha hape ka mor'a ho hlapolla ka metsi. 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.
tshebediso
1, e sebelisoang e le sesebelisoa se 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.
2. E le moemeli oa ho kenella le oa ho kolobisa, e ka sebelisoa mekhoeng e sa tšoaneng ea indasteri ea khatiso ea masela le ho daea, joalo ka enzyme deizing, wool carbonization, cashmere shrinking, chlorination, rayon silk processing. 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.
3, sehlahisoa se na le phemello e ntle haholo, ho koloba, emulsification, ho hasana le thepa ea ho foam. 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, e sebelisoang haholo e le sesebelisoa sa ho koloba le ho kolobisa, e ka sebelisoa hape joalo ka sesepa, thuso ea dae, dispersant, chefo e bolaeang likokoanyana le herbicide, jj.
Mekhoa ea tlhahiso
1, naphthalene le butanol, sulfuric acid ka sulfonation condensation. Tšebeliso ea lintho tse tala (kg/t) naphthalene 300 n-butanol 300 octanol 45 smoke sulfuric acid 840 sulfuric acid 450 caustic soda 190 no powder 100
2. Qhala likarolo tse 426 tsa naphthalene likarolong tse 478 tsa n-butanol, eketsa likarolo tse 1 060 tsa concentrated sulfuric acid ebe u eketsa likarolo tse 320 tsa fuming sulfuric acid tlas'a pherekano. 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.
