Nekal BX, sodium butylnaphthalene sulfonate, ine maitiro asingaenderani zvakanyanya. Kune sodium butyl naphthalene sulfonate uye isobutyl naphthalene sulfonate. Pane nzira mbiri dzekugadzira maindasitiri eNekal 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. Iyo yakagadzikana mumvura yakaoma, munyu, asidhi uye isina simba alkaline mhinduro, uye chena precipitate mune concentrated caustic soda. Inogona kunyungudutswa zvakare mushure mekudonha nemvura. 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.
use
1, inoshandiswa sechinhu chinopinda muindasitiri yekudhinda machira nekudhaya. Inogona zvakare kushandiswa se detergent, dhayi aid, dispersant, wetting agent, insecticide, herbicide uye emulsifier mukugadzira rabha indasitiri.
2. Sechinhu chinopinda uye chekunyorova, chinogona kushandiswa mumhando dzakasiyana dzekudhinda machira uye dhayi indasitiri, senge enzyme deizing, wool carbonization, cashmere shrinking, chlorination, rayon silk processing. 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.
3, chigadzirwa 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 seyekupinda mumiririri uye weti mumiririri, zvakare inogona kushandiswa se detergent, dhayi aid, dispersant, insecticide uye herbicide, nezvimwe.
Nzira dzekugadzira
1, naphthalene uye butanol, sulfuric acid ne sulfonation condensation. Raw material inoshandiswa (kg/t) naphthalene 300 n-butanol 300 octanol 45 utsi sulfuric acid 840 sulfuric acid 450 caustic soda 190 no powder 100
2. Dissolve 426 zvikamu zve naphthalene mu 478 zvikamu zve n-butanol, wedzera 1 060 zvikamu zve concentrated sulfuric acid uye wobva wawedzera 320 zvikamu zvefuming sulfuric acid pasi pekushungurudzika. 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.
