Ko nga roopu mahi ka taea te whakangao, te whakawhaariki ranei e te SO3 ka wehewehea ki nga waahanga e 4; te mowhiti benzene, te roopu hydroxyl waipiro, te here rua, te A-waro o te roopu Ester, ko nga rauemi mata e rite ana ko te alkylbenzene, te waipiro ngako (ether), te korefin, te waikawa ngako methyl ester(FAME), ko nga hua angamaheni he ahumahi raina alkyl benzene sulfonate (i muri nei. ka kiia ko LAS), AS, AES, AOS me MES. Ko nga mea e whai ake nei hei whakauru i te mana whakawhanaketanga o te waikawa sulfonic me nga riu ngawha i runga i te whakarōpūtanga e nga roopu mahi waro ka taea te whakangao e SO3.
2.1 alkylaryl sulfonates
Ko te Alkyl aryl sulfonate e pa ana ki te karaehe o nga kaitao sulfonate i mahia e te tauhohenga sulfonation me te whanariki trioxide me te mowhiti kakara hei roopu mahi waro. Ko nga hua angamaheni ko te LAS me te mekameka roa-roa alkyl benzene sulfonate, Heavy alkylbenzene sulfonate (HABS), petroleum sulfonate me te alkyl diphenyl ether disulfonate, etc.
2.1.1 Ahumahi rārangi alkyl benzene sulfonate
Ka whiwhihia te LAS ma te sulfonation, te koroheketanga, te hauwai me te whakakore i te alkylbenzene. Ko te nuinga o nga wa ka rongoahia te LAS me te hoko i te ahua o te waikawa sulfonic alkylbenzene. I roto i te whakamahi tūturu, kua whakakorehia ki te alkali. He mea rongoa ano ka hokona hei tote konutai. Ko te LAS he pai te whakamakuku, te whakaemulsifying, te hukahuka me te whakaheke, a he pai te hototahi ki etahi atu surfactants (AOS, AES, AEO), a he maha nga waahanga o nga tono i roto i nga waahi horoi whare penei i te paura horoi, te horoi me te wai horoi. Ko te kino o te LAS ko te kore o te aukati ki te wai pakeke. Ko te tikanga he mea tika ki te taapiri i te konupūmā me te konupora katote chelating āpiha i te wa e whakamahia ana. I tua atu, ko te LAS he tino whakaheke, he ahua kino ki te kiri.
2.1.2 roa-mekameka alkyl benzene sulfonate
Ko te roa-mekameka alkyl benzene sulfonate e tohu ana ki te karaehe surfactants me te roa o te mekameka waro nui ake i te 13, he pai te mahi tono mo te whakaora hinu tuatoru, a he maha nga wa e whakamahia ana ki te whakakotahitanga me te konupora alkyl benzene sulfonate taumaha. Ko te tikanga whanui ko te whakamahi i te HF hei whakakorikori ki te hanga i te mahi alkylation na roto i te wai taumaha o te wax dehydrogenation hua, penei i nga alkanes mekameka roa, te ranunga olelfin me te Benzene, te Xylene ranei hei whakarite Long chain alkyl benzene. Na ka whakamahi i te whakangao sulfonation membrane SO3 ki te whakarite waikawa sulfonic alkylbenzene mekameka roa.
2.1.3 Alkyl benzene sulfonate taumaha
Ko te kaha o te alkylbenzene sulfonate tetahi o nga tino waikura e whakamahia ana i roto i nga waipuke o te papa hinu. Ko ona rauemi mata he alkylbenzene taumaha he hua o te hanga o te dodecylbenzene, he iti ake te hua (<10%), no reira he iti tona puna. Ko nga waahanga o te alkylbenzene taumaha he uaua, ko te nuinga ko te alkylbenzene, te dialkylbenzene,
diphenylene, alkylindane, tetralin me etahi atu.
2.1.4 Te hinu sulfonate
Ko te hinu sulfonate hinu he momo surfactant kua whakaritea e te SO3 sulfonation o te hinu whakangao hinu. Ko te whakaritenga o te hinu sulfonate te nuinga o te waa ka whakamahia te hinu hinu hinu o te mara hinu hei rauemi mata. Ko te tukanga o te sulfonation ko: hau SO3 kiriata sulfonation, wai SO3 kettle sulfonation, me te hau SO3 rehu sulfonation.
2.1.5 Alkyl Diphenyl Ether Disulfonate(ADPEDS)
Ko te Alkyl diphenyl ether disulfonate he karaehe o nga kaimoana mahi me nga roopu waikawa sulfonic rua i roto i te ngota ngota. He tono motuhake i roto i te polymerization whakaehunga, horoi whare me te ahumahi, tā pueru me te tae. Ka whakatauritea ki nga riipene monosulfonate tuku iho (pēnei i te LAS), ka hoatu e nga roopu waikawa disulfonik etahi ahuatanga motuhake o te tinana me te matū, he tino pai te whakarewatanga me te pumau i roto i te 20% te waikawa kaha, te kawakawa kaha, te tote parakore me nga otinga o nga kaihoko whakangao. Kei roto ko te monoalkyl diphenyl ether bissulfonate (MADS), te monoalkyl diphenyl ether monosulfonate (MAMS), me te dialkyl Diphenyl ether bissulfonate (DADS) me te bisalkyl diphenyl ether monosulfonate (DAMS) kua tito, ko te waahanga matua ko MADS, a he nui atu i te 80%. Ko te hua sulfonated o alkyl diphenyl ether, alkyl diphenyl ether disulfonic acid, he tino pokey teitei. Ko te tikanga, ka whakamahia te dichloroethane hei whakarewa me te whakarite ma te tukanga whakangao piro.
