8. Dzina la ndaniNekala BXSodium butyl Naphthalene Sulfonate? Onse sodium butyl naphthalene sulfonatendi isobutyl sodium sulfonate. Pali njira ziwiri zopangira mafakitale za Nekal BX:

(1) Naphthalene ndi yemweyo kulemera kwa sulfuric asidi sulfonation, mapangidwe α -naphthalene sulfonic asidi, pansi kwambiri yogwira ntchito nthawi yomweyo kuwonjezera anaikira sulfuric asidi ndi n-butanol, pambuyo kulekana, neutralization, evaporation.

② Naphthalene inasakanizidwa ndi n-butanol, ndipo sulfuric acid yowonjezera inawonjezeredwa. Pambuyo pa neutralization ndi kuyanika, chomalizidwacho chinapezedwa. Izi ndi woyera ndi kuwala chikasu ufa, sungunuka m'madzi. Khola mu madzi olimba, mchere, asidi ndi ofooka zamchere njira, mu anaikira caustic koloko woyera mpweya, kuwonjezera madzi pambuyo dilution akhoza kachiwiri kusungunuka.

Mankhwalawa ndi amtundu wa anion, okhutira ndi madzi osapitirira 2%, chitsulo sichiposa 0.01%, pH mtengo wa 1% yankho lamadzimadzi 7 ~ 8.5. Kuphatikiza pa permeability wamphamvu, ilinso ndi emulsification, kufalikira ndi kutulutsa thovu, kusakhoza kuyeretsa bwino, komanso kuyimitsidwa koyipa kwa fumbi. Izi zitha kugwiritsidwa ntchito kwambiri ngati zolowera m'njira zopaka utoto, zopaka utoto komanso utoto. Itha kugwiritsidwanso ntchito ngati utoto wa cosolvent, wothandizira utoto wopaka utoto wa asidi, wothandizira utoto wopaka utoto wa utoto, wothandizira utoto wopaka utoto wa polyamide, wothandizira utoto wopaka utoto wa polyester / thonje wophatikizika wopaka utoto. Mankhwala katundu Woyera kapena wachikasu ufa. Zosungunuka m'madzi.

Zogwiritsidwa ntchito pakupanga nsalu, kusindikiza ndi utoto, zikopa ndi mapepala, komanso mankhwala ophera tizilombo, chonyowetsa herbicide, utoto ndi inki wobalalitsira wothandizira, emulsifier yamakampani a mphira amagwiritsa ntchito Chemicalbook ngati yolowera mumakampani osindikiza nsalu ndi utoto. Itha kugwiritsidwanso ntchito ngati zotsukira, zothandizira utoto, dispersant, wonyowetsa, mankhwala ophera tizilombo, herbicide ndi emulsifier mumakampani opanga mphira. Ntchito ngati permeating wothandizila ndi kunyowetsa wothandizila, angagwiritsidwe ntchito njira zosiyanasiyana zosindikizira nsalu ndi dyeing makampani, monga enzyme desizing, ubweya carbonization, kuchepa cashmere, chlorination, rayon silika mankhwala.CAS: 25638-17-9.

Itha kugwiritsidwanso ntchito ngati chonyowetsa pakupanga mapepala ndi makampani am'nyanja. Kuwonjezera 10% yankho lolowera la BX mu organic pigment ndikopindulitsa pakusinthira phala. Amagwiritsidwa ntchito ngati emulsifier pokonzekera mphira zamkati. The mankhwala ali kwambiri permeability, kunyowetsa, emulsification, diffusion ndi thovu katundu. Mu kukana kwa asidi, kukana kwa alkali, kukana kwamadzi olimba, kukana kwa mchere, kuwonjezera mchere pang'ono kumatha kukulitsa mphamvu. Amagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zamakampani osindikizira nsalu ndi utoto, omwe amagwiritsidwa ntchito kwambiri ngati zotsekemera komanso zonyowetsa, zitha kugwiritsidwanso ntchito ngati zotsukira, zothandizira utoto, dispersant, mankhwala ophera tizilombo ndi herbicide, etc. Njira yopanga Naphthalene woyengedwa ndi butanol, sulfuric acid ndi sulfonation. condensation.

Kugwiritsa ntchito zopangira (kg/t) Naphthalene woyengedwa 300 n-butanol 300 sec-octanol 45 Fuming sulfuric acid 840 450 sulfate caustic soda 190 ufa wopanda phokoso 100 Njira yopanga Sungunulani magawo 426 a naphthalene mu 478 n-0 sulfuric acid owonjezera 199 n-butano ya sulfuriki oyambitsa, ndiye kuwonjezera fuming asidi sulfuric 320 mbali. Gabi adatenthedwa pang'onopang'ono mpaka 50-55 ℃ ndikusungidwa kwa 6h. Pambuyo pa kuyima, asidi wapansi amamasulidwa. The chapamwamba anachita njira ndi neutralized ndi mchere, ndiyeno bleached ndi sodium hypochlorite, sedimentation, kusefera, kupopera mbewu mankhwalawa ndi kuyanika kupeza yomalizidwa mankhwala.
