2.3 Olefin sulfonate
Sodium olefin sulfonate imhando ye sulfonate surfactant inogadzirwa ne sulfonating olefins se mbishi zvinhu zvine sulfur trioxide. Zvinoenderana nechinzvimbo chechisungo cheviri, inogona kukamurwa kuita a-alkenyl sulfonate (AOS) uye Sodium yemukati olefin sulfonate (IOS).
2.3.1 a-alkenyl sulfonate (AOS)
AOS ikirasi ye sulfonate surfactants inowanikwa kubva ku-olefins (inowanzo shandiswa C14~C18 olefins) kuburikidza nesulfonation, neutralization uye hydrolysis. AOS imwe mhando yeyakakura-yakakura surfactant inogadzirwa mushure meLAS neAES. AOS chaizvoizvo musanganiswa sodium alkenyl sulfonate (60% ~ 70%), sodium hydroxyalkyl sulfonate (30%) uye sodium disulfonate (0~10%). Chigadzirwa chacho chinowanzouya nemhando mbiri: 35% yemvura uye 92% yehupfu.
Yakakwira kabhoni ketani AOS (C2024AOS) ine yakanaka plugging kugona mukupisa tembiricha furo mafashama, izvo zvinoita kuti ive yakanaka yekushandisa tarisiro.
2.3.2 Sodium yemukati olefin sulfonate (IOS)
Internal olefin sulfonate (inonzi IOS) imhando ye sulfonate surfactant inowanikwa kubva mukati olefin kuburikidza nesulfonation, neutralization uye hydrolysis. Chiyero che sodium hydroxy sulfonate kune sodium alkenyl sulfonate muIOS zvigadzirwa zvinoenderana nekuti kana kusachembera kunoitika mushure me sulfonation: kana olefin yemukati yakanyatsogadziriswa mushure me sulfonation pasina kuchembera, chigadzirwa chine 90% hydroxy sulfonic acid Sodium uye 10% sodium alkenyl. sulfonate; kana iyo olefin yemukati isingagadziriswi mushure me sulfonation uye kukwegura, zvinyorwa zve sodium hydroxysulfonate muchigadzirwa zvichaderera, zvinyorwa zve sodium alkenyl sulfonate zvichawedzera, uye mafuta emahara uye inorganic munyu Izvo zvinyorwa zvinokwirawo. Mukuwedzera, iyo sulfonic acid boka reIOS riri pakati pekabhoni chain, ichiita mukati olefin sulfonate ine "double hydrophobic tail chain". Zvigadzirwa zveIOS zvakasviba muruvara kupfuura AOS uye zvinonyanya kushandiswa mune mamwe maindasitiri minda.
2.4 Sodium fatty acid methyl ester sulfonate
Sodium fatty acid methyl sulfonate (MES) inowanzoita mhando ye surfactant inowanikwa kubva kuC16 ~ 18 fatty acid methyl ester kuburikidza neSO3 sulfonation, kukwegura, re-esterification bleaching, uye neutralization. Musiyano mukugadzira tekinoroji uri kunyanya mukupenya uye esterification. Kutevedzana kwemakemikari maitiro anogona kuverengerwa kune acid bleaching, neutral bleaching uye yechipiri bleaching tekinoroji. MES ine yakanaka decontamination kugona, calcium sipo yekuparadzira simba rakasimba, uye zviri nyore kuita biodegrade.
