Nekal BX, ka sodium butylnaphthalene sulfonate, loaʻa nā ʻano like ʻole. Aia ka sodium butyl naphthalene sulfonate a me ka isobutyl naphthalene sulfonate. ʻElua mau ʻano hana ʻenehana noNekal BX:
(1) Naphthalene a me ke kaumaha like o ka sulfuric acid sulfonation, ka hoʻokumu ʻana o ka α -naphthalene sulfonic acid, ma lalo o ka hoʻoulu ʻana i ka manawa like me ka hoʻohui ʻana i ka sulfuric acid a me ka n-butanol, ma hope o ka hoʻokaʻawale ʻana, neutralization, evaporation.
② Ua hui ʻia ka Naphthalene me ka n-butanol, a ua hoʻohui ʻia ka ʻakika sulfuric concentrated. Ma hope o ka neutralization a me ka maloʻo, ua loaʻa ka huahana i hoʻopau ʻia. He keʻokeʻo kēia huahana a me ka pauka melemele māmā, hiki ke hoʻoheheʻe ʻia i ka wai. Paʻa ia i loko o ka wai paʻakikī, ka paʻakai, ka waikawa a me ka hopena alkaline nāwaliwali, a me ka wai keʻokeʻo i loko o ka soda caustic concentrated. Hiki ke hoʻoheheʻe hou ʻia ma hope o ka hoʻoheheʻe ʻana me ka wai. ʻO ka huahana he ʻano anion, ʻaʻole ʻoi aku ka nui o ka wai ma mua o 2%, ʻaʻole i ʻoi aku ka nui o ka hao ma mua o 0.01%, ka waiwai pH o 1% aqueous solution 7 ~ 8.5. Ma waho aʻe o ka permeability ikaika, loaʻa iā ia ka emulsification, diffusion a me ka huʻihuʻi waiwai, hiki ke hoʻomaʻemaʻe maikaʻi ʻole, a me ka hoʻokuʻu ʻana i ka lepo.
Hiki ke hoʻohana nui ʻia kēia huahana ma ke ʻano he penetrant i ke kaʻina hana ʻana, bleaching a me ke kala. Hiki ke hoʻohana ʻia ma ke ʻano he cosolvent dye, kōkua hoʻoluʻu huluhulu waika, kōkua hoʻoluli huluhulu hoʻoheheʻe, kōkua hoʻoluʻu lole polyamide, kōkua hoʻoluʻu lole polyester/pulu pulu.
hoʻohana
1, hoʻohana ʻia ma ke ʻano he penetrating agent i ka paʻi textile a me ka ʻoihana dyeing. Hiki ke hoʻohana ʻia e like me ka mea hoʻomaʻemaʻe, kōkua dye, dispersant, wetting agent, insecticide, herbicide a me ka emulsifier i ka ʻoihana synthetic rubber.
2. E like me ka mea penetrant a me ka pulu, hiki ke hoʻohana ʻia i nā ʻano hana like ʻole o ka paʻi lole a me ka ʻoihana kala, e like me ka enzyme desizing, wool carbonization, cashmere shrinking, chlorination, rayon silk processing. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe i ka hana pepa a me ka ʻoihana loko. ʻO ka hoʻohui ʻana i 10% penetrant BX solution i loko o ka puaʻa organik he mea maikaʻi ia i ka modulation paste kala. Hoʻohana ʻia e like me ka emulsifier i ka hoʻomākaukau ʻana i ka pulp pulupulu.
3, loaʻa i ka huahana ka permeability maikaʻi loa, wetting, emulsification, diffusion and foaming properties. I ka acid resistance, alkali resistance, hard water resistance, inorganic paakai paʻakai, hoʻohui i kahi liʻiliʻi o ka paʻakai hiki ke hoʻonui nui i ka permeability. Hoʻohana nui ʻia i nā ʻano hana like ʻole o ka paʻi lole a me ka ʻoihana dyeing, hoʻohana nui ʻia e like me ka permeating agent a me ka wetting agent, hiki ke hoʻohana ʻia e like me ka detergent, dye aid, dispersant, insecticide and herbicide, etc.
Hana hana
1, naphthalene a me butanol, sulfuric acid e ka sulfonation condensation. Ka hoʻohana ʻana i nā mea maka (kg/t) naphthalene 300 n-butanol 300 octanol 45 uahi sulfuric acid 840 sulfuric acid 450 caustic soda 190 ʻaʻohe pauka 100
2. E hoopau i na apana 426 o ka naphthalene i na apana 478 o ka n-butanol, e hookui i 1 060 apana o ka waika sulfuric concentrated a laila e hui i 320 mau apana o ka waikawa sulfuric fuming me ka hoouluulu. Ua hoʻomehana mālie ʻia ʻo Gabi i 50-55 ℃ a mālama ʻia no 6h. Ma hope o ke kū ʻana, hoʻokuʻu ʻia ka waika lalo. Hoʻokuʻu ʻia ka hopena hopena o luna me ka alkali, a laila bleached me ka sodium hypochlorite, sedimentation, kānana, hoʻoheheʻe ʻia a maloʻo e loaʻa ka huahana i hoʻopau ʻia.
