2.3 Olefin sulfonate
Sodium olefin sulfonate wani nau'i ne na sulfonate surfactant wanda aka shirya ta hanyar sulfonating olefins azaman albarkatun ƙasa tare da sulfur trioxide. Dangane da matsayi na haɗin biyu, ana iya raba shi zuwa a-alkenyl sulfonate (AOS) da Sodium Internal olefin sulfonate (IOS).
2.3.1 a-alkenyl sulfonate (AOS)
AOS wani nau'i ne na sulfonate surfactants da aka samo daga a-olefins (wanda aka fi amfani da C14 ~ C18 olefins) ta hanyar sulfonation, neutralization da hydrolysis. AOS wani nau'i ne na babban sikelin surfactant da aka samar bayan LAS da AES. AOS shine ainihin cakuda sodium alkenyl sulfonate (60% ~ 70%), sodium hydroxyalkyl sulfonate (30%) da sodium disulfonate (0 ~ 10%). Samfurin yawanci yana zuwa cikin nau'i biyu: 35 % Na ruwa da 92% na foda.
High sarkar carbon AOS (C2024AOS) yana da kyau plugging ikon a high zafin jiki kumfa ambaliya, wanda ya sa shi da kyau aikace-aikace al'amurra.
2.3.2 Sodium ciki olefin sulfonate (IOS)
Olefin sulfonate na ciki (wanda ake magana da shi azaman IOS) wani nau'in sulfonate surfactant ne wanda aka samu daga olefin na ciki ta hanyar sulfonation, neutralization da hydrolysis. Matsakaicin sodium hydroxy sulfonate zuwa sodium alkenyl sulfonate a cikin samfuran IOS ya dogara ne akan ko tsufa yana faruwa bayan sulfonation: idan olefin na ciki ya kasance mai narkewa kai tsaye bayan sulfonation ba tare da tsufa ba, samfurin ya ƙunshi kusan 90% hydroxy sulfonic acid Sodium da 10% sodium alkenyl. sulfonate; idan olefin na ciki ya zama neutralized bayan sulfonation da tsufa, abun ciki na sodium hydroxysulfonate a cikin samfurin zai ragu, abun ciki na sodium alkenyl sulfonate zai karu, da man fetur da kuma inorganic salts abun ciki kuma ya tashi. Bugu da ƙari, ƙungiyar sulfonic acid na IOS tana cikin tsakiyar sarkar carbon, ta samar da sulfony olefin na ciki tare da tsarin "tsarin wutsiya biyu na hydrophobic". Kayayyakin IOS sun fi AOS duhu duhu kuma ana amfani da su a wasu filayen masana'antu.
2.4 Sodium fatty acid methyl ester sulfonate
Sodium fatty acid methyl sulfonate (MES) yawanci nau'in surfactant ne da aka samu daga C16 ~ 18 fatty acid methyl ester ta hanyar SO3 sulfonation, tsufa, sake-esterification bleaching, da neutralization. Bambanci a fasahar samarwa shine yafi a cikin bleaching da esterification. Za'a iya dangana jerin tsarin sinadarai zuwa bleaching acid, bleaching tsaka tsaki da fasahar bleaching na biyu. MES yana da kyakkyawan iyawar gurɓatawa, ikon watsa sabulun calcium yana da ƙarfi, kuma yana da sauƙin haɓaka.
