8. Zita raaniNekal BXSodium butyl Naphthalene Sulfonate? Ose ari maviri Sodium butyl naphthalene sulfonateuye isobutyl sodium sulfonate. Pane nzira mbiri dzekugadzira maindasitiri dzeNekal BX:

(1) Naphthalene uye uremu hwakafanana hwe sulfuric acid sulfonation, kuumbwa kwe α -naphthalene sulfonic acid, pasi pekukurudzira kwakanyanya panguva imwechete kuwedzera concentrated sulfuric acid uye n-butanol, mushure mekuparadzana, neutralization, evaporation.

② Naphthalene yakasanganiswa ne-n-butanol, uye concentrated sulfuric acid yakawedzerwa. Mushure mokunge neutralization uye kuomeswa, chigadzirwa chakapedzwa chakawanikwa. Ichi chigadzirwa chakachena uye chakareruka yero hupfu, soluble mumvura. Yakagadzikana mumvura yakaoma, munyu, asidhi uye isina simba alkaline mhinduro, mu concentrated caustic soda white precipitation, wedzera mvura mushure me dilution inogona kunyungudika zvakare.

Chigadzirwa chacho chinonzi anion type, mvura yemukati haisi kupfuura 2%, iron content haisi kupfuura 0.01%, pH kukosha kwe1% aqueous solution 7 ~ 8.5. Pamusoro pekupinza kwakasimba, ine zvakare emulsification, kupararira uye kupupa zvinhu, kusagona kuchenesa, uye kusamira zvakanaka kweguruva. Ichi chigadzirwa chinogona kushandiswa zvakanyanya sechinopinda mukukwesha, kuchena uye kudhaya maitiro. Inogona zvakare kushandiswa sedhayi cosolvent, asidhi dhayi dhayi dhayi mubatsiri, kuparadzira dhayi dhayi dhayi mubatsiri, polyamide yakasanganiswa jira dyeing mubatsiri, paradzira dhayi polyester / donje rakasanganiswa jira mubatsiri. Chemical properties Off-white or yellowish powder. Soluble mumvura.

Zvishandiso zvemachira, kudhinda uye dhayi, matehwe nemapepa indasitiri, pamwe nemishonga yezvipembenene, herbicide wetting agent, pendi neingi inoparadzira agent, indasitiri yerabha emulsifier inoshandisa Chemicalbook seinopinda muindasitiri yekudhinda machira nekudhaya. Inogona zvakare kushandiswa se detergent, dhayi aid, dispersant, wetting agent, insecticide, herbicide uye emulsifier mukugadzira rabha indasitiri. Shandisa senge inopenyerera mumiriri uye yekunyorovesa mumiriri, inogona kushandiswa mumhando dzakasiyana dzemachira ekudhinda uye dhayi indasitiri, senge enzyme deizing, mvere dzemakushe, kuderera kwe cashmere, chlorination, rayon silk kurapwa.CAS:25638-17-9.

Inogona zvakare kushandiswa seanonyorova mumiriri mukugadzira mapepa uye indasitiri yegungwa. Kuwedzera 10% inopinza BX mhinduro mune organic pigment inobatsira kumisa mavara modulation. Inoshandiswa se emulsifier mukugadzira rubber pulp. Chigadzirwa chacho chine yakanakisa permeability, wetting, emulsification, diffusion uye furo zvinhu. Mukupikisa asidhi, alkali kuramba, kuoma kwemvura kuramba, inorganic munyu kuramba, kuwedzera munyu mushoma kunogona kuwedzera kupinza zvakanyanya. Inoshandiswa zvakanyanya mumhando dzakasiyana dzemachira ekudhinda uye dhayi indasitiri, inonyanya kushandiswa seinopinza mumiririri uye weti mumiririri, zvakare inogona kushandiswa se detergent, dhayi aid, dispersant, mushonga wezvipembenene uye herbicide, etc. Nzira yekugadzira Yakanatswa naphthalene nebutanol, sulfuric acid ne sulfonation. condensation.

Raw material kushandiswa (kg/t) Yakanatswa naphthalene 300 n-butanol 300 sec-octanol 45 Fuming sulfuric acid 840 450 sulfate caustic soda 190 silent powder 100 Nzira yekugadzira Dissolve naphthalene 426 parts mu 478 n-concentric acid 0 sulfuric 0 concentrated kubvongodza, wobva wawedzera fuming sulfuric acid 320 parts. Gabi yakadziiswa zvishoma nezvishoma kusvika 50-55 ℃ uye yakachengetwa kwe6h. Mushure mekumira, pasi pasi asidi inosunungurwa. Iyo yekumusoro reaction solution inogadziriswa nealkali, yobva yasvibiswa nesodium hypochlorite, sedimentation, filtration, spraying uye kuomesa kuti uwane chigadzirwa chapera.
