Sodium dodecylbenzene sulfonate ruaj khov rau alkali, dilute acid thiab dej tawv.
Nws tuaj yeem tsim kom muaj qhov sib npaug nrog cov kua qaub muaj zog:
R12-Ph-SO3Na+HCl⇌R12-Ph-SO3H+ NaCl
Cov pab pawg hydroxyl hauv pawg sulfo kuj tseem tuaj yeem hloov tau los ntawm chlorine atom los tsim sulfonyl chloride:
3R12-Ph-SO3Na + PCl3 → R12-Ph-SO3H + NaCl (~ 200 degree)
Hydrolysis cov tshuaj tiv thaiv yog qhov rov qab cov tshuaj tiv thaiv sulfonation. Nyob rau hauv catalysis ntawm muaj zog acid, sodium dodecyl sulfate thiab dej yuav co rhuab kom tshem tawm cov sulfo pawg. Lub ntsiab lus ntawm cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv electrophilic hloov ntawm H + raws li tus neeg sawv cev electrophilic tawm tsam lub nplhaib aromatic.
3R12-Ph-SO3Na + H2O → R12-Ph + NaHSO4 (~ 200 degree, H2SO4)
Laboratory npaj txoj kev:
Ntxiv 35 milliliters (34.6 grams) ntawm dodecylbenzene rau hauv 250 milliliters plaub lub caj dab ntim nrog lub tshuab ua kom sov, ntsuas kub, lub raj xa dej, thiab reflux condenser. Maj mam ntxiv 35 milliliters ntawm 98% sulfuric acid thaum stirring. Qhov kub yuav tsum tsis pub tshaj 40 ° C.
Tom qab ntxiv, qhov kub yuav tsum tau nce mus rau 60-70 ° C rau 2 teev.
Txias cov saum toj no -hais sulfonation tov tov rau 40-50℃C, maj mam ntxiv cov dej uas tsim nyog (kwv yees li 15 mL), ncuav nws mus rau hauv ib qho kev sib cais funnel, cia nws sawv ntsug rau ib pliag, ces muab tso rau nws dua, ntws cov txheej qis (dej thiab inorganic ntsev), thiab khaws cov txheej sab sauv (organic theem).
Npaj 80 milliliters ntawm 10% sodium hydroxide tov thiab ntxiv rau kwv yees li 60-70 milliliters ntawm 250 milliliters plaub lub raj mis. Maj mam ntxiv cov organic theem thaum nplawm, tswj qhov kub ntawm 40-50 ° C, kho pH rau 7-8 nrog 10% sodium hydroxide, thiab sau tag nrho cov nyiaj ntawm 10% sodium hydroxide.
Ntxiv ib qho me me ntawm sodium chloride rau hauv cov tshuaj tiv thaiv saum toj no, lim tom qab lub nplhaib nkag mus rau qhov tseeb, thiab tau txais cov khoom siv dawb, uas yogsodium dodecyl benzenesulfonate hmoov.
Muaj txoj hauv kev:
Nws yog npaj los ntawm reacting dodecylbenzene nrog fumigant sulfuric acid los yog sulfur trioxide, thiab ces neutralizing nws nrog alkali.
Qhov tsis zoo ntawm kev siv fumigation sulfuric acid rau sulfonation yog tias yuav muaj qee cov kua qaub pov tseg hauv cov khoom sulfonated tom qab cov tshuaj tiv thaiv. Cov sodium sulfate ua tom qab neutralization yog nkag mus rau hauv cov khoom, cuam tshuam nws purity.
Tam sim no, sulfonation ntawm sulfur trioxide cua sib tov yog dav siv hauv kev lag luam. Sulfur trioxide tuaj yeem distilled los ntawm 60% fumigated sulfuric acid, los yog hlawv nyob rau hauv ib lub qhov cub nrog leej faj thiab cua qhuav kom tau ib tug sib tov roj uas muaj sulfur dioxide.
Cov roj sib xyaw yog nkag mus rau hauv lub tshuab hluav taws xob sulfonation nruab nrog alkylbenzene rau sulfurization. Cov tshuaj sulfonated nkag mus rau hauv nruab nrab qhov system, neutralize nrog sodium hydroxide tov, thiab thaum kawg nkag mus rau lub tshuab ziab khaub ncaws kom qhuav. Cov khoom tau txais yog hmoov nrog zoo fluidity.
Sodium dodecyl benzenesulfonate hmoov(SDBS) yog ib qho anionic surfactant dav siv nyob rau hauv ntau yam xws li tshuaj niaj hnub, kev lag luam, thiab tshuaj vim nws zoo heev tu, foaming, thiab emulsifying zog. Nws cov kev siv tseem ceeb yog raws li nram no:
1. Ntxuav muaj nuj nqi
Sodium alkylbenzenesulfonate yog cov roj daj daj uas tuaj yeem ua kom huv si los ua kom muaj zog hexagonal lossis rhombohedral phaj-zoo li cov muaju. Nws muaj toxicity tsawg thiab tau lees paub tias yog cov khoom siv tshuaj lom neeg muaj kev nyab xeeb los ntawm International Safety Organization. Sodium alkylbenzenesulfonate tuaj yeem siv rau hauv cov txiv hmab txiv ntoo thiab cov khoom siv ntxuav tais diav, nrog rau cov khoom siv ntau tshaj plaws hauv cov tshuaj ntxuav tes. Vim yog kev siv loj - nplai automated ntau lawm thiab tus nqi qis, sodium alkylbenzenesulfonate siv rau hauv cov tshuaj ntxuav tes muaj ob hom: branched saw qauv (ABS) thiab ncaj saw qauv (LAS).
Cov qauv saw caj dab muaj tsawg biodegradability thiab tuaj yeem ua rau muaj kuab paug rau ib puag ncig, thaum cov saw ncaj ncaj yog yooj yim rau biodegrade, nrog rau biodegradability ntau dua 90% thiab qis qis ntawm ib puag ncig muaj kuab paug.
Sodium dodecyl benzenesulfonate hmoovyog nruab nrab, rhiab rau dej hardness, tsis yooj yim rau oxidize, muaj zog foaming zog, siab tu lub zog, yooj yim rau tov nrog ntau yam additives, tsis muaj nqi, mature synthesis txheej txheem, thiab daim ntawv thov dav. Nws yog ib qho zoo heev anionic surfactant. Nws muaj qhov cuam tshuam loj heev rau cov av hauv av, cov av protein thiab cov av oily, tshwj xeeb tshaj yog nyob rau hauv cov av granular ntawm ntuj fibers.
Nws muaj peev xwm decontamination nce nrog qhov nce ntawm qhov kub thiab txias, thiab nws cov nyhuv ntawm cov plua plav protein ntau dua li cov uas tsis yog -ionic surfactants, thiab ua npuas ncauj yog nplua nuj. Txawm li cas los, muaj ob drawbacks. Ua ntej, nws muaj kev tiv thaiv tsis zoo rau cov dej tawv, thiab nws cov kev ua haujlwm tu tuaj yeem txo qis nrog cov dej tawv. Yog li ntawd, cov tshuaj detergents uas siv nws ua tus neeg sawv cev tseem ceeb yuav tsum tau ua ke nrog tus nqi tsim nyog ntawm cov tshuaj chelate.
Qhov thib ob yog vim li cas nws muaj zog degreasing lub zog, uas tuaj yeem ua rau qee qhov khaus ntawm daim tawv nqaij thaum ntxuav tes. Tom qab ntxuav, cov khaub ncaws muaj qhov tsis zoo ntawm tes, thiab nws raug nquahu kom siv cationic surfactants ua softeners rau rinsing. Nyob rau hauv xyoo tas los no, txhawm rau kom ua tiav cov txiaj ntsig zoo ntawm kev ntxuav, nws feem ntau siv ua ke nrog cov tsis muaj -ionic surfactants xws li fatty cawv polyoxyethylene ether (AEO). Lub hom phiaj tseem ceeb yog npaj ntau hom kua, hmoov, thiab granular detergents, tshuaj ntxuav, thiab tshuaj ntxuav tes.
2. Emulsifying dispersant
Emulsifier yog ib yam khoom uas txhim kho qhov nro ntawm qhov sib txawv ntawm ntau theem nyob rau hauv ib qho emulsion, tsim ib qho kev sib txawv thiab ruaj khov dispersed system lossis emulsion. Emulsifiers yog cov khoom siv ntog nrog ob pawg hydrophilic thiab oleophilic hauv lawv cov molecules.
Lawv sib sau ua ke ntawm cov roj / dej sib cuam tshuam, txo cov kev sib tshuam ntawm lub ntsej muag thiab txo lub zog xav tau los tsim emulsions, yog li ua kom lub zog ntawm emulsions. Raws li anionic surfactant, nws muaj kev ua haujlwm zoo, muaj zog hydrophilicity, txo qhov nro ntawm cov roj - dej interface, thiab ua tiav emulsification. Yog li ntawd, nws tau siv dav hauv kev tsim cov emulsions xws li tshuaj pleev ib ce, zaub mov, luam ntawv thiab dyeing auxiliaries, tshuaj tua kab, thiab lwm yam.
3. Antistatic tus neeg sawv cev
Txhua yam khoom nqa nws tus kheej li qub, uas tuaj yeem ua rau tsis zoo lossis zoo. Lub tsub zuj zuj ntawm cov nqi zoo li qub tuaj yeem cuam tshuam lossis ua rau lub neej txhua hnub lossis kev tsim khoom lag luam. Cov tshuaj uas qhia thiab tshem tawm cov nqi tsim kev puas tsuaj kom tsis txhob ua rau tsis yooj yim lossis tsim kev puas tsuaj rau kev tsim khoom lossis lub neej hu ua anti- cov tshuaj tiv thaiv zoo li qub. Nws yog ib qho anionic surfactant uas tuaj yeem ua rau saum npoo ntawm cov ntaub, yas, thiab lwm yam ntaub ntawv ntau dua hydrophilic. Nyob rau tib lub sijhawm, ionic surfactants kuj muaj cov nyhuv conductive, uas tuaj yeem ua rau hluav taws xob zoo li qub kom xau raws sijhawm, yog li txo qhov txaus ntshai thiab tsis yooj yim los ntawm hluav taws xob zoo li qub.
4. Lwm cov haujlwm
Sodium dodecyl benzenesulfonate hmoovmuaj ntau yam kev siv. Ntxiv rau cov ntawv thov saum toj no -hais txog, nws kuj yog siv los ua tus neeg sawv cev ua kom zoo rau cov paj rwb ntaub, tus neeg sawv cev desizing, tus neeg sawv cev theem thaum dyeing, thiab cov hlau degreaser hauv cov txheej txheem hlau electroplating; Siv los ua ib qho resin dispersant, hnov ntxhiab tsw, thiab de ink tus neeg sawv cev hauv kev lag luam ntawv; Siv raws li kev nkag mus degreaser hauv kev lag luam tawv; Siv los ua tus neeg sawv cev tiv thaiv caking hauv kev lag luam chiv; Siv los ua tus neeg saib xyuas huab cua hauv ntau yam ntawm kev lag luam cement, ib leeg lossis ua cov khoom sib xyaw ua ke.
