Mapoka anoshanda anogona kuve sulfonated kana sulfated neSO3 anonyanya kukamurwa muzvikamu zvina; benzene ring, alcohol hydroxyl group, double bond, A-carbon yeEster group, zvinhu zvakasvibirira zvinoenderana nealkylbenzene, mafuta edoro (ether), olefin, fatty acid methyl ester(FAME), zvinowanzoitika maindasitiri ane mutsara alkyl benzene sulfonate (mushure meizvi. inonzi LAS), AS, AES, AOS uye MES. Izvi zvinotevera kuunza chimiro chekusimudzira cheiyo iripo sulfonic acid uye sulfate surfactants zvinoenderana neyakakamurwa neiyo organic inoshanda mapoka anogona sulfonated neSO3.

2.1 alkylaryl sulfonates
Alkyl aryl sulfonate inoreva kirasi ye sulfonate surfactants yakagadzirwa ne sulfonation reaction ne sulfur trioxide ine inonhuhwirira mhete se organic inoshanda boka. Zvigadzirwa zvakajairika zvinosanganisira LAS uye refu-chain alkyl benzene sulfonate, Heavy alkylbenzene sulfonate (HABS), petroleum sulfonate uye alkyl diphenyl ether disulfonate, nezvimwe.

2.1.1 Industrial linear alkyl benzene sulfonate
LAS inowanikwa ne sulfonation, kuchembera, hydrolysis uye neutralization yealkylbenzene. LAS inowanzochengetwa uye inotengeswa nenzira yealkylbenzene sulfonic acid. Mukushandiswa chaiko, inonatsirwa nealkali. Kune zvakare akachengetwa uye anotengeswa muchimiro se sodium munyu. LAS ine kunyorova kwakanaka, emulsifying, foaming uye detergency, uye inoenderana zvakanaka nemamwe ma surfactants (AOS, AES, AEO), uye ine huwandu hwakawanda hwekushandisa muminda yekuwachisa yemumba senge poda yekuwachisa, detergent uye mvura yekuwachisa. Izvo zvisingabatsiri zveLAS ndezvokudzivirira kwakashata kumvura yakaoma. Zvinowanzodikanwa kuwedzera calcium uye magnesium ion chelating agents panguva yekushandiswa. Pamusoro pezvo, LAS inodzikisira zvakanyanya uye ine kumwe kushatirwa paganda.
2.1.2 refu-cheni alkyl benzene sulfonate
Long-chain alkyl benzene sulfonate kazhinji inoreva kirasi yevano surfactants ine kabhoni cheni kureba inodarika gumi nenhatu, ine kushanda kwakanaka kwekushandisa mukudzoreredza mafuta epamusoro, uye inowanzoshandiswa pamwe chete neheavy alkyl benzene sulfonate. Zvinoitwa ndezvekushandisa HF sechinhu chinokonzeresa kuita alkylation action by heavy liquid wax dehydrogenation chigadzirwa, senge marefu-chain alkanes, olelfin musanganiswa neBenzene kana Xylene kugadzirira Long cheni alkyl benzene. Zvadaro shandisa SO3 membrane sulfonation kugadzirira refu-chain alkylbenzene sulfonic acid.
2.1.3 Heavy alkyl benzene sulfonate
Heavy alkylbenzene sulfonate ndeimwe yeakanyanya surfactants anoshandiswa mumafashama munhandare yemafuta. Yayo mbishi inorema alkylbenzene ndeye-chigadzirwa chekugadzirwa kwedodecylbenzene, goho rakaderera (<10%), saka sosi yayo ishoma. Izvo zvinorema zvealkylbenzene zvakaoma, kunyanya kusanganisira alkylbenzene, dialkylbenzene,
diphenylene, alkylindane, tetralin uye zvichingodaro.
2.1.4 Petroleum sulfonate
Petroleum sulfonate imhando ye surfactant yakagadzirwa neSO3 sulfonation ye petroleum distillate mafuta. Kugadziriswa kwepetroleum sulfonate kunowanzo shandisa petroleum distillate oiri yenzvimbo yemafuta seyakagadzirwa. Iyo sulfon process inosanganisira: gasi SO3 firimu sulfon, mvura SO3 kettle sulfation, uye gasi SO3 pfapfaidzo sulfon.
2.1.5 Alkyl Diphenyl Ether Disulfonate(ADPEDS)
Alkyl diphenyl ether disulfonate ikirasi yeanoshanda surfactants ane maviri sulfonic acid mapoka mumorekuru. Iyo ine yakakosha mashandisirwo emulsion polymerization, imba uye indasitiri yekuchenesa, machira kudhinda uye dhayi. Zvichienzaniswa netsika monosulfonate surfactants (akadai LAS), disulfonic asidhi mapoka anopa imwe inokosha muviri uye kemikari ehupfumi, izvo zvakanaka kwazvo solubility uye kugadzikana mu 20% yakasimba asidhi, simba alkali, inorganic munyu uye bleaching mumiririri mhinduro. Inosanganisira monoalkyl diphenyl ether bissulfonate (MADS), monoalkyl diphenyl ether monosulfonate (MAMS), uye dialkyl Diphenyl ether bissulfonate (DADS) uye bisalkyl diphenyl ether monosulfonate (DAMS) inoumbwa, chikamu chikuru chinopfuura MADS, uye zvinyorwa zvayo. 80%. Iyo sulfonated chigadzirwa chealkyl diphenyl ether, alkyl diphenyl ether disulfonic acid, ine viscosity yakakwirira kwazvo. Kazhinji, dichloroethane inoshandiswa sechinhu chinonyungudutsa uye yakagadzirirwa nekettle sulfon process.
