8. Lub npe hu li casNias BXSodium butyl Naphthalene Sulfonate? Ob leeg Sodium butyl naphthalene sulfonatethiab isobutyl Sodium sulfonate. Muaj ob txoj hauv kev tsim khoom rau Nekal BX:
(1) Naphthalene thiab tib qhov hnyav ntawm sulfuric acid sulfonation, tsim ntawm α -naphthalene sulfonic acid, nyob rau hauv khaus nplawm tib lub sij hawm ntxiv concentrated sulfuric acid thiab n-butanol, tom qab sib cais, neutralization, evaporation.
② Naphthalene tau tov nrog n-butanol, thiab cov concentrated sulfuric acid ntxiv. Tom qab neutralization thiab ziab, cov khoom tiav tau txais. Cov khoom no yog dawb thiab lub teeb daj hmoov, soluble hauv dej. Ruaj khov nyob rau hauv cov dej tawv, ntsev, kua qaub thiab tsis muaj zog alkaline tov, nyob rau hauv concentrated caustic soda dawb nag lossis daus, ntxiv dej tom qab dilution tuaj yeem rov ua dua.
Cov khoom yog hom anion, cov ntsiab lus dej tsis ntau tshaj 2%, cov ntsiab lus hlau tsis ntau tshaj 0.01%, pH tus nqi ntawm 1% aqueous tov 7 ~ 8.5. Ntxiv rau qhov muaj zog permeability, nws kuj muaj emulsification, diffusion thiab foaming zog, tsis muaj peev xwm tu, thiab tsis zoo tshem tawm cov plua plav. Cov khoom no tuaj yeem siv dav hauv kev siv tshuaj tua kab, tshuaj dawb thiab dyeing txheej txheem. Nws kuj tseem siv tau los ua dye cosolvent, acid dye wool dyeing assistant, disperse dye wool dyeing assistant, polyamide blended fabric dyeing assistant, disperse dye polyester/patton blended fabric dyeing assistant. Chemical properties Off-dawb los yog yellowish hmoov. Soluble hauv dej.
Siv rau textile, luam ntawv thiab dyeing, tawv thiab ntawv kev lag luam, raws li zoo raws li tshuaj tua kab, herbicide wetting agent, xim thiab number case dispersing tus neeg saib xyuas, roj hmab kev lag luam emulsifier siv Chemicalbook li penetrant nyob rau hauv textile printing thiab dyeing kev lag luam. Nws kuj tseem siv tau los ua cov tshuaj ntxuav tes, tshuaj pleev xim, tshuaj dispersant, tus neeg sawv cev ntub dej, tshuaj tua kab, tshuaj tua kab thiab emulsifier hauv kev lag luam roj hmab hluavtaws. Siv ua tus neeg sawv cev permeating thiab tus neeg sawv cev ntub dej, tuaj yeem siv ntau yam txheej txheem ntawm textile printing thiab dyeing kev lag luam, xws li enzyme desizing, wool carbonization, cashmere shrinking, chlorination, rayon txhob lo lo ntxhuav.CAS: 25638-17-9.
Nws kuj tseem siv tau los ua tus neeg sawv cev ntub dej hauv papermaking thiab pas dej kev lag luam. Ntxiv 10% penetrant BX tov nyob rau hauv cov organic pigment yog pab tau rau xim paste modulation. Siv ua emulsifier hauv kev npaj cov roj hmab pulp. Cov khoom muaj zoo permeability, ntub dej, emulsification, diffusion thiab foaming zog. Nyob rau hauv acid tsis kam, alkali tsis kam, tawv dej tsis kam, inorganic ntsev tsis kam, ntxiv ib tug me me ntsev yuav ua tau zoo heev permeability. Dav siv nyob rau hauv ntau yam txheej txheem ntawm textile printing thiab dyeing kev lag luam, feem ntau yog siv raws li permeating tus neeg saib xyuas thiab wetting tus neeg saib xyuas, kuj yuav siv tau raws li detergent, dye pab, dispersant, insecticide thiab herbicide, thiab lwm yam. condensation.
Raw khoom noj (kg/t) Refined naphthalene 300 n-butanol 300 sec-octanol 45 Fuming sulfuric acid 840 450 sulfate caustic soda 190 uas ntsiag to hmoov 100 Ntau txoj kev Dissolve naphthalene 426 qhov chaw nyob rau hauv 478 concentrate n-butanic acid, ntxiv rau sulfuric acid. stirring, ces ntxiv fuming sulfuric acid 320 qhov chaw. Gabi tau maj mam rhuab mus rau 50-55 ℃ thiab khaws cia rau 6h. Tom qab sawv ntsug, lub hauv paus acid raug tso tawm. Cov tshuaj tiv thaiv sab saud yog nruab nrab nrog alkali, thiab tom qab ntawd bleached nrog sodium hypochlorite, sedimentation, pom, txau thiab ziab kom tau cov khoom tiav.
