2.1.1 Alkyl benzene sulfonate ea liindasteri ea mela
LAS e fumanoa ka sulfation, botsofali, hydrolysis le neutralization ea alkylbenzene. LAS hangata e bolokoa le ho rekisoa ka mokhoa oa alkylbenzene sulfonic acid. Ha e sebelisoa, ha e sebelisoe ka alkali. Ho boetse ho na le ho bolokoa le ho rekisoa ka foromo e le letsoai la sodium. LAS e na le metsi a matle, emulsifying, foaming le detergency, 'me e lumellana hantle le li-surfactants tse ling (AOS, AES, AEO),' me e na le mefuta e mengata ea likopo masimong a ho hlatsoa malapeng a kang phofo ea ho hlatsoa, ​​sesepa le mokelikeli oa ho hlatsoa. Bothata ba LAS ke ho hanyetsa ha eona metsi a thata. Hangata hoa hlokahala ho eketsa lisebelisoa tsa calcium le magnesium ion chelating nakong ea tšebeliso. Ho phaella moo, LAS e fokotseha haholo 'me e na le ho teneha ho itseng letlalong.
2.1.2 alkyl benzene sulfonate ea ketane e telele
Long-chain alkyl benzene sulfonate hangata e bolela sehlopha sa li-surfactants tse bolelele ba ketane ea khabone e fetang 13, e nang le ts'ebetso e ntle ea ho hlaphoheloa ha oli ea thuto e phahameng, 'me hangata e sebelisoa hammoho le alkyl benzene sulfonate e boima. Ts'ebetso e akaretsang ke ho sebelisa HF joalo ka mokelikeli ho etsa alkylation ketso ka sehlahisoa se boima sa boka ba metsi, joalo ka li-alkanes tse telele, motsoako oa olelfin le Benzene kapa Xylene ho lokisa ketane e telele ea alkyl benzene. Ebe u sebelisa SO3 lera salfonation ho lokisetsa ketane e telele alkylbenzene sulfonic acid.
2.1.3 Alkyl benzene sulfonate e boima
Heavy alkylbenzene sulfonate ke e 'ngoe ea li-surfactants tse ka sehloohong tse sebelisoang likhoholang tsa oli. Thepa ea eona e boima ea alkylbenzene ke sehlahisoa sa tlhahiso ea dodecylbenzene, chai e tlase (<10%), kahoo mohloli oa eona o lekanyelitsoe. Likarolo tsa alkylbenzene tse boima li batla li rarahane, haholo-holo ho kenyelletsa alkylbenzene, dialkylbenzene,

2.1.4 Petroleum sulfonate
Petroleum sulfonate ke mofuta oa surfactant e entsoeng ke SO3 sulfonation ea petroleum distillate oli. Ho lokisoa ha petroleum sulfonate hangata ho sebelisa oli ea lehae ea petroleum distillate ea tšimo ea oli e le thepa e tala. Ts'ebetso ea sulfonation e kenyelletsa: sulfonation ea filimi ea khase ea SO3, sulfonation ea metsi ea SO3 kettle, le khase ea SO3 spray sulfonation.
2.1.5 Alkyl Diphenyl Ether Disulfonate(ADPEDS)
Alkyl diphenyl ether disulfonate ke sehlopha sa li-surfactants tse sebetsang tse nang le lihlopha tse peli tsa sulfonic acid ka har'a molek'hule. E na le lisebelisoa tse khethehileng ho emulsion polymerization, ho hloekisa malapa le indasteri, khatiso ea masela le ho daea. Ha ho bapisoa le li-surfactants tsa setso tsa monosulfonate (tse kang LAS), lihlopha tsa disulfonic acid li e fa thepa e itseng e khethehileng ea 'mele le ea lik'hemik'hale, e leng hantle haholo ho qhibiliha le botsitso ka 20% ea acid e matla, alkali e matla, letsoai le inorganic le tharollo ea bleaching. E na le monoalkyl diphenyl ether bissulfonate (MADS), monoalkyl diphenyl ether monosulfonate (MAMS), le dialkyl Diphenyl ether bissulfonate (DADS) le bisalkyl diphenyl ether monosulfonate (DAMS) li entsoe, karolo e kholo ke MADS, le litaba tsa eona. 80%.
