2.3 I-Olefin sulfonate
I-sodium olefin sulfonate luhlobo lwe-sulfonate surfactant elungiswe yi-sulfonating olefins njengezinto eziluhlaza ezinesulfure trioxide. Ngokwesikhundla se-double bond, inokwahlulwa ibe yi-alkenyl sulfonate (AOS) kunye neSodium yangaphakathi olefin sulfonate (IOS).
2.3.1 a-alkenyl sulfonate (AOS)
I-AOS iklasi ye-sulfonate surfactants efunyenwe kwi-a-olefins (esetyenziswa ngokuqhelekileyo i-C14 ~ C18 olefins) nge-sulfonation, neutralization kunye ne-hydrolysis. I-AOS lolunye uhlobo lwe-surfactant enkulu eyenziwe emva kwe-LAS kunye ne-AES. I-AOS ngokwenene ngumxube we-sodium alkenyl sulfonate (60% ~ 70%), i-sodium hydroxyalkyl sulfonate (30%) kunye ne-sodium disulfonate (0 ~ 10%). Imveliso idla ngokuza ngeendlela ezimbini: i-35% yolwelo kunye ne-92% yomgubo.
Ikhonkco lekhabhoni ephezulu i-AOS(C2024AOS) inamandla okufaka iplagi kubushushu obuphezulu besikhukula sogwebu, nto leyo eyenza ukuba ibe nethemba losetyenziso oluhle.
2.3.2 I-Sodium yangaphakathi ye-olefin sulfonate (IOS)
I-olefin sulfonate yangaphakathi (ebizwa ngokuba yi-IOS) luhlobo lwe-sulfonate surfactant efunyenwe kwi-olefin yangaphakathi nge-sulfonation, neutralization kunye ne-hydrolysis. Umlinganiselo we-sodium hydroxy sulfonate kwi-sodium alkenyl sulfonate kwiimveliso ze-IOS kuxhomekeke ekubeni ukuguga kwenzeka emva kwe-sulfonation: ukuba i-olefin yangaphakathi ingathathi hlangothi ngokuthe ngqo emva kwe-sulfonation ngaphandle kokuguga, imveliso iqulethe malunga ne-90% ye-hydroxy sulfonic acid kunye ne-10% ye-alkenyl ye-sodium. isulfonate; ukuba i-olefin yangaphakathi ingathathi hlangothi emva kwe-sulfonation kunye nokuguga, umxholo we-sodium hydroxysulfonate kwimveliso uya kuncipha, umxholo we-sodium alkenyl sulfonate uya kwanda, kunye neoli yamahhala kunye neetyuwa ze-inorganic Umxholo uphinde uphakame. Ukongezelela, iqela le-sulfonic acid ye-IOS liphakathi kwe-carbon chain, lenza i-olefin sulfonate yangaphakathi kunye ne-"double hydrophobic tail chain". Iimveliso ze-IOS zimnyama ngombala kune-AOS kwaye zisetyenziswa ikakhulu kwezinye iindawo zoshishino.
2.4 I-sodium fatty acid i-methyl ester sulfonate
I-sodium fatty acid methyl sulfonate (MES) ngokuqhelekileyo luhlobo lwe-surfactant efunyenwe kwi-C16 ~ 18 i-fatty acid methyl ester ngokusebenzisa i-SO3 sulfonation, ukuguga, i-esterification bleaching, kunye ne-neutralization. Umahluko kwitekhnoloji yokuvelisa ubukhulu becala ku-bleaching kunye ne-esterification. Ulandelelwano lwenkqubo yeekhemikhali lunokuthi lufakwe kwi-acid bleaching, i-bleaching engathathi hlangothi kunye neteknoloji ye-bleaching yesibini. I-MES inamandla okuphelisa ungcoliseko, amandla okusasaza isepha yekhalsiyam yomelele, kwaye kulula ukuwohloka kwezinto eziphilayo.
