Tsawg chromaticity thiab siab - zoo methyl palmitic acid yog tsim los siv 3A molecular sieve sab nraud ncig adsorption lub cev qhuav dej tshuab, nrog palmitic acid thiab methanol ua raw khoom thiab NKC-9 resin ua catalyst. Cov thev naus laus zis no muaj qhov zoo ntawm kev ua haujlwm yooj yim, cov tshuaj tiv thaiv me me, cov khoom lag luam siab purity, thiab cov txiaj ntsig siab, muab txoj hauv kev tshiab thiab siv tau zoo rau kev sib txuas ntawm cov khoom.
Cov kauj ruam tshwj xeeb yog raws li nram no:
(1) Kev npaj cov khoom siv raw: palmitic acid, methanol, NKC-9 resin catalyst, thiab 3A molecular sieve.
(2) Sib tov palmitic acid thiab methanol hauv ib qho kev faib ua feem, ntxiv NKC-9 resin catalyst, thiab do sib npaug.
(3) Nyob rau hauv qhov kev txiav txim ntawm 3A molecular sieve sab nraud ncig adsorption lub cev qhuav dej tshuab, qhov sib tov yog dehydrated.
(4) Tshav kub lub cev qhuav dej kom dhau los ua cov tshuaj tiv thaiv esterification ntawm palmitic acd thiab methanol.
(5) Tom qab cov tshuaj tiv thaiv tiav, cov khoom yog txias thiab crystallized rau cov khoom sib cais.
Cov hauv qab no yog chemical equation rau txoj kev no:
CH3CH2CH2COH + CH3OH=CH3CH2CH2COOB3 + H2O
Hauv cov tshuaj tiv thaiv, CH3CH2CH2COOH sawv cev rau palmitic acd, CH3OH sawv cev rau methanol, CH3CH2CH2COOCH3 sawv cev rau methyl palmitic acd, thiab H2O sawv cev dej. Cov tshuaj tiv thaiv yog cua sov thiab cov catalyst yog NKC-9 cob.
Cov kauj ruam ntxaws ntxaws rau kev sib txuasmethyl palmitate hmoovlos ntawm cov txheej txheem esterification ncaj qha yog raws li hauv qab no:
Cov khoom siv raw: palmitic acd, methanol, catalyst (feem ntau sulfuric acd los yog sodium hydroxide), thiab cov kuab tshuaj tsim nyog.
Kev npaj cov khoom siv: agitator, rhaub, condenser, cais, thiab cov kav dej tsim nyog.
(1) Sib tov palmitic acid thiab methanol nyob rau hauv ib qho piv txwv molar. Feem ntau, cov molar piv ntawm 1: 1 thiab 1: 5. Qhov kev faib ua feem yuav tsum tau txiav txim siab raws li cov kev mob tshwm sim thiab qhov xav tau qib ntawm esterification.
(2) Ntxiv catalyst rau qhov sib tov. Yog hais tias sulfuric acd yog siv los ua ib qho catalyst, cov nyiaj ib txwm ntxiv yog 0.5% mus rau 2% ntawm qhov loj ntawm palmitic acd. Yog tias siv sodium hydroxide, qhov sib ntxiv yog feem ntau 0.5% mus rau 1% ntawm qhov loj methanol. Lub luag haujlwm ntawm lub catalyst yog kom ceev cov tshuaj tiv thaiv esterification.
(3) Nyob rau hauv qhov kev txiav txim ntawm ib tug stirrer, qhov sib tov yog rhuab mus rau qhov kub thiab txias. Feem ntau hais lus, esterification tshwm sim nyob rau hauv qhov kub ntawm 60-100 degree. Qhov tshwj xeeb kub yuav tsum raug txiav txim raws li hom catalyst thiab cov tshuaj tiv thaiv.
(4) Tuav lub sijhawm tshuaj tiv thaiv kom tso cai rau cov tshuaj tiv thaiv esterification ua tiav. Lub sijhawm tshuaj tiv thaiv feem ntau yog nyob nruab nrab ntawm 2-8 teev, thiab lub sijhawm tshwj xeeb yuav tsum tau txiav txim siab raws li cov tshuaj tiv thaiv kev nce qib thiab cov khoom lag luam.
Kev sib npaug tshuaj lom neeg yog raws li nram no:
CH3(CH2)14COV + CH3OH → CH3(CH2)14COOB3 + H2O
Qhov kev sib npaug no piav qhia txog cov txheej txheem ntawm esterification ntawm palmitic acid (CH3 (CH2) 14COOH) thiab methanol (CH3OH) nrog lub catalyst los tsim methyl palmitic acid (CH3 (CH2) 14COOCH3) thiab dej (H2O).
(1) Tom qab cov tshuaj tiv thaiv tiav, txias cov tshuaj tiv thaiv thiab cais cov methyl palmitate thiab cov ntaub ntawv raw uas tsis muaj kev cuam tshuam los ntawm kev sib cais. Txoj kev sib cais feem ntau yog siv txoj hauv kev xws li distillation lossis rho tawm.
(2) Ua kom huv qhov sib cais kom tshem tawm tej yam tsis huv. Txoj kev purification feem ntau yog distillation lossis crystallization.
(3) Ntsuam xyuas cov khoom purified kom paub tseeb tias nws zoo raws li cov qauv. Txoj kev tshawb pom feem ntau yog kev tshuaj xyuas chromatographic lossis spectroscopic tsom xam, thiab lwm yam.
Nyob rau hauv cov txheej txheem ncaj qha esterification, concentrated sulfuric acd hnyav corrodes cov khoom, ua rau nws nyuaj rau cais cov khoom. Txoj kev tshaj tawm - cov txheej txheem kho yog nyuaj, thiab cov dej khib nyiab ua rau muaj kuab paug ib puag ncig loj. Tsis tas li ntawd, muaj zog oxidizing nyhuv ntawm concentrated sulfuric acd thaum lub sij hawm cov tshuaj tiv thaiv txheej txheem yuav yooj yim ua rau cov xim ntawm cov khoom mus rau darken. Yog li ntawd, nyob rau hauv xyoo tas los no, ib tug series ntawm ib puag ncig tus phooj ywg catalysts tau siv los hloov sulfuric acd, nrog rau ntau yam txheej txheem txhim kho technologies los txhim kho esterification tus nqi, xws li cerium phosphotungstate, hloov SBA-15 molecular sieve, ionic kua, Ti/Ti/si solid accs, NKChydration, microwave dehydration, NKC-9 dehydration, microwave resin ntau tshaj. technology, thiab lwm yam. Lub molecular sieve adsorption lub cev qhuav dej technology yog mature thiab yooj yim los txhawb.
