Nias BX, sodium butylnaphthalene sulfonate, muaj cov qauv tsis sib xws. Muaj sodium butyl naphthalene sulfonate thiab isobutyl naphthalene sulfonate. Muaj ob txoj kev tsim khoom lag luam rauNias 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. Nws yog ruaj khov nyob rau hauv dej tawv, ntsev, kua qaub thiab qaug zog alkaline tov, thiab dawb precipitate nyob rau hauv concentrated caustic soda. Nws tuaj yeem yaj dua tom qab diluting nrog dej. 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.
siv
1, siv los ua tus neeg saib xyuas hauv kev lag luam textile thiab dyeing. 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.
2. Raws li tus neeg sawv cev thiab cov dej ntub dej, nws tuaj yeem siv rau hauv ntau yam txheej txheem ntawm textile printing thiab dyeing kev lag luam, xws li enzyme desizing, wool carbonization, cashmere shrinking, chlorination, rayon silk ua. 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.
3, 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, tsuas 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 tshuaj tua kab, thiab lwm yam.
Txoj kev tsim khoom
1, naphthalene thiab butanol, sulfuric acid los ntawm sulfonation condensation. Raw khoom noj (kg/t) naphthalene 300 n-butanol 300 octanol 45 pa luam yeeb sulfuric acid 840 sulfuric acid 450 caustic soda 190 tsis muaj hmoov 100
2. Dissolve 426 qhov chaw ntawm naphthalene nyob rau hauv 478 qhov chaw ntawm n-butanol, ntxiv 1 060 qhov chaw ntawm concentrated sulfuric acid thiab ces ntxiv 320 qhov chaw ntawm fuming sulfuric acid nyob rau hauv agitation. 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.
