2.3 Olefin sulfonate
Sodium olefin sulfonate jẹ iru sulfonate surfactant ti a pese sile nipasẹ sulfonating olefins bi awọn ohun elo aise pẹlu sulfur trioxide.Ni ibamu si awọn ipo ti awọn ė mnu, o le ti wa ni pin si a-alkenyl sulfonate (AOS) ati Sodium ti abẹnu olefin sulfonate (IOS).
2.3.1 a-alkenyl sulfonate (AOS)
AOS jẹ kilasi ti sulfonate surfactants ti a gba lati awọn a-olefins (ti a lo nigbagbogbo C14 ~ C18 olefins) nipasẹ sulfonation, neutralization ati hydrolysis.AOS jẹ miiran iru ti o tobi-asekale surfactant ti a ṣe lẹhin LAS ati AES.AOS jẹ gangan adalu iṣuu soda alkenyl sulfonate (60% ~ 70%), sodium hydroxyalkyl sulfonate (30%) ati sodium disulfonate (0 ~ 10%).Ọja naa nigbagbogbo wa ni awọn ọna meji: 35% Ti omi ati 92% ti lulú.
Ẹwọn erogba giga AOS (C2024AOS) ni agbara plugging ti o dara ni iṣan omi foomu otutu ti o ga, eyiti o jẹ ki o ni awọn asesewa ohun elo to dara.
2.3.2 Sodium ti abẹnu olefin sulfonate (IOS)
Olefin sulfonate ti inu (ti a tọka si bi IOS) jẹ iru sulfonate surfactant ti a gba lati inu olefin inu nipasẹ sulfonation, didoju ati hydrolysis.Ipin ti iṣuu soda hydroxy sulfonate si sodium alkenyl sulfonate ninu awọn ọja IOS da lori boya tabi kii ṣe ọjọ ogbó waye lẹhin sulfonation: ti olefin inu ba wa ni didoju taara lẹhin sulfonation laisi ogbo, ọja naa ni nipa 90% hydroxy sulfonic acid Sodium ati 10% sodium alkenyl sulfonate;ti olefin ti inu ba jẹ didoju lẹhin sulfonation ati ti ogbo, akoonu ti iṣuu soda hydroxysulfonate ninu ọja naa yoo dinku, akoonu ti iṣuu soda alkenyl sulfonate yoo pọ si, ati epo ọfẹ ati awọn iyọ inorganic akoonu tun ga soke.Ni afikun, ẹgbẹ sulfonic acid ti IOS wa ni aarin pq erogba, ti o n ṣe sulfonate olefin ti inu pẹlu eto “ẹwọn iru hydrophobic meji” kan.Awọn ọja IOS ṣokunkun ni awọ ju AOS ati pe a lo ni akọkọ ni diẹ ninu awọn aaye ile-iṣẹ.
2.4 Iṣuu soda fatty acid methyl ester sulfonate
Iṣuu soda fatty acid methyl sulfonate (MES) jẹ igbagbogbo iru surfactant ti a gba lati C16 ~ 18 fatty acid methyl ester nipasẹ SO3 sulfonation, ti ogbo, bleaching re-esterification, ati neutralization.Iyatọ ti imọ-ẹrọ iṣelọpọ jẹ pataki ni bleaching ati esterification.Ọkọọkan ti ilana kemikali ni a le sọ si bleaching acid, bleaching didoju ati imọ-ẹrọ bleaching Atẹle.MES ni agbara imukuro ti o dara, ọṣẹ kalisiomu ti n tuka agbara lagbara, ati pe o rọrun lati biodegrade.
