2.3 I-Olefin sulfonate
I-sodium olefin sulfonate iwuhlobo lwe-sulfonate surfactant olulungiswe ngama-olefin e-sulfonating njengezinto zokusetshenziswa ezine-sulphur trioxide.Ngokwesikhundla se-double bond, ingahlukaniswa i-alkenyl sulfonate (AOS) ne-Sodium yangaphakathi ye-olefin sulfonate (IOS).
2.3.1 a-alkenyl sulfonate (AOS)
I-AOS iyikilasi lama-sulfonate surfactants atholakala ku-a-olefins (evame ukusetshenziswa C14~C18 olefins) ngokusebenzisa i-sulfonation, neutralization kanye ne-hydrolysis.I-AOS ingolunye uhlobo lwe-surfactant enkulu ekhiqizwa ngemuva kwe-LAS ne-AES.I-AOS empeleni iyingxube ye-sodium alkenyl sulfonate (60% ~70%), i-sodium hydroxyalkyl sulfonate (30%) kanye ne-sodium disulfonate (0~10%).Umkhiqizo uvame ukuza ngezindlela ezimbili: 35 % Of liquid kanye 92% of powder.
I-high carbon chain AOS(C2024AOS) inekhono elihle lokuxhuma ekukhukhuleni kwegwebu lokushisa eliphezulu, okulenza libe namathemba amahle ohlelo lokusebenza.
2.3.2 I-Sodium yangaphakathi ye-olefin sulfonate (IOS)
I-olefin sulfonate yangaphakathi (ebizwa ngokuthi i-IOS) iwuhlobo lwe-sulfonate surfactant etholakala ku-olefin yangaphakathi ngokusebenzisa i-sulfonation, neutralization kanye ne-hydrolysis.Isilinganiso se-sodium hydroxy sulfonate ku-sodium alkenyl sulfonate emikhiqizweni ye-IOS sincike ekutheni ukuguga kwenzeka noma cha ngemva kwe-sulfonation: uma i-olefin yangaphakathi ingathathi hlangothi ngokuqondile ngemva kwe-sulfonation ngaphandle kokuguga, umkhiqizo uqukethe cishe i-90% ye-hydroxy sulfonic acid ne-10% ye-alkenyl ye-sodium. i-sulfonate;uma i-olefin yangaphakathi ingathathi hlangothi ngemuva kwe-sulfonation nokuguga, okuqukethwe kwe-sodium hydroxysulfonate emkhiqizweni kuzokwehla, okuqukethwe kwe-sodium alkenyl sulfonate kuzokwanda, futhi uwoyela wamahhala kanye nosawoti we-inorganic Okuqukethwe nakho kukhuphuka.Ngaphezu kwalokho, iqembu le-sulfonic acid le-IOS liphakathi kwe-carbon chain, lenza i-olefin sulfonate yangaphakathi ene-"double hydrophobic tail chain" isakhiwo.Imikhiqizo ye-IOS inombala omnyama kune-AOS futhi isetshenziswa kakhulu kwezinye izimboni.
2.4 I-sodium fatty acid i-methyl ester sulfonate
I-sodium fatty acid methyl sulfonate (MES) imvamisa iwuhlobo lwe-surfactant etholakala ku-C16~18 fatty acid methyl ester ngokusebenzisa i-SO3 sulfonation, ukuguga, i-re-esterification bleaching, kanye ne-neutralization.Umehluko kubuchwepheshe bokukhiqiza ikakhulukazi ku-bleaching kanye ne-esterification.Ukulandelana kwenqubo yamakhemikhali kungase kubangelwe ukufiphala kwe-asidi, ukufiphala okungathathi hlangothi kanye nobuchwepheshe bokwenza uketshezi okwesibili.I-MES inekhono elihle lokuqeda ukungcola, amandla okuhlakaza insipho ye-calcium anamandla, futhi kulula ukuwohloka kwemvelo.
