2.1 alkylaryl sulfonates
Alkyl aryl sulfonate yana nufin wani aji na sulfonate surfactants shirya ta sulfonation dauki tare da sulfur trioxide tare da aromatic zobe a matsayin Organic aiki kungiyar. Abubuwan da aka saba sun haɗa da LAS da dogon sarkar alkyl benzene sulfonate, Heavy alkylbenzene sulfonate (HABS), man fetur sulfonate da alkyl diphenyl ether disulfonate, da dai sauransu.

2.1.1 Masana'antu madaidaiciya alkyl benzene sulfonate
Ana samun LAS ta hanyar sulfonation, tsufa, hydrolysis da neutralization na alkylbenzene. LAS yawanci ana adanawa kuma ana sayar da shi ta hanyar alkylbenzene sulfonic acid. A cikin ainihin amfani, an cire shi tare da alkali. Hakanan ana adanawa ana sayar da su a cikin nau'i azaman gishirin sodium. LAS yana da kyau wetting, emulsifying, kumfa da kuma detergency, kuma yana da kyau dacewa da sauran surfactants (AOS, AES, AEO), kuma yana da fadi da kewayon aikace-aikace a cikin gida wanka filayen kamar wanki foda, detergent da wanka ruwa.

Bugu da ƙari, LAS yana ƙazanta sosai kuma yana da ɗan haushi ga fata.
2.1.2 dogon sarkar alkyl benzene sulfonate
Dogon sarkar alkyl benzene sulfonate yawanci yana nufin nau'in surfactants tare da tsayin sarkar carbon sama da 13, wanda ke da kyakkyawan aikin aikace-aikacen a dawo da mai na manyan makarantu, kuma galibi ana amfani dashi tare da babban alkyl benzene sulfonate. Tsarin gabaɗaya shine yin amfani da HF azaman mai haɓakawa don yin aikin alkylation ta samfuran ruwan kakin zuma mai nauyi, irin su alkanes mai tsayi, cakuda olelfin tare da Benzene ko Xylene don shirya Long sarkar alkyl benzene. Sa'an nan kuma amfani da SO3 membrane sulfonation don shirya dogon sarkar alkylbenzene sulfonic acid.
2.1.3 Alkyl benzene sulfonate mai nauyi
Alkylbenzene sulfonate mai nauyi yana ɗaya daga cikin manyan abubuwan da ake amfani da su a cikin ambaliya ta mai. Danyen kayan sa mai nauyi alkylbenzene shine ta hanyar samar da tsarin samar da dodecylbenzene, yawan amfanin ƙasa ya ragu (<10%), don haka tushen sa yana da iyaka. Abubuwan da ke cikin alkylbenzene masu nauyi suna da ɗan rikitarwa, galibi sun haɗa da alkylbenzene, dialkylbenzene,
diphenylene, alkylindane, tetralin da sauransu.
2.1.4 Sulfate na man fetur
Sulfate na man fetur wani nau'in surfactant ne wanda SO3 sulfonation na man distillate mai ya shirya. Shirye-shiryen sulfonate na man fetur yawanci yana amfani da man distillate mai na gida na filin mai a matsayin ɗanyen abu. Tsarin sulfonation ya haɗa da: iskar gas SO3 fim sulfonation, ruwa SO3 kettle sulfonation, da gas SO3 fesa sulfonation.
2.1.5 Alkyl Diphenyl Ether Disulfonate (ADPEDS)
Alkyl diphenyl ether disulfonate rukuni ne na surfactants masu aiki tare da ƙungiyoyin sulfonic acid guda biyu a cikin kwayoyin halitta. Yana da aikace-aikace na musamman a cikin emulsion polymerization, tsabtace gida da masana'antu, bugu da rini. Idan aka kwatanta da na al'ada monosulfonate surfactants (kamar LAS), disulfonic acid kungiyoyin ba shi wasu musamman jiki da kuma sinadaran Properties, waxanda suke da kyau solubility da kwanciyar hankali a cikin 20% karfi acid, karfi alkali, inorganic gishiri da bleaching wakili mafita. Ya ƙunshi monoalkyl diphenyl ether bissulfonate (MADS), monoalkyl diphenyl ether monosulfonate (MAMS), da dialkyl Diphenyl ether bissulfonate (DADS) da bisalkyl diphenyl ether monosulfonate (DAMS) an hada su, babban bangaren shi ne MADS, kuma abun ciki ya fi fiye da. 80%. Samfurin sulfonated na alkyl diphenyl ether, alkyl diphenyl ether disulfonic acid, yana da ɗanko mai yawa. Gabaɗaya, ana amfani da dichloroethane azaman kaushi kuma ana shirya shi ta hanyar sulfonation na kettle.
