Nres dej yog qhov nruab nrab nruab nrab ntawm lub tsheb nres tsheb, thiab nws qhov kev ua tau zoo cuam tshuam rau kev nyab xeeb ntawm kev tsav tsheb. Vim nws qhov kub kub taw tes, tsis tshua muaj hygroscopicity, thiab kev ruaj ntseg tshuaj zoo, nws tau dhau los ua cov khoom tseem ceeb rau cov dej nres.
1. Nres kua mis mis
Nyob rau hauv DOT 3 thiab DOT 4 nres cov kua dej, raws li azeotrope, qhov kub ntawm qhov kub ntawm cov dej nres tuaj yeem hloov kho (qhuav qhov kub ntawm qhov kub siab tshaj los yog sib npaug li 205 degree, ntub qhov kub ntawm qhov kub siab tshaj lossis sib npaug li 140 degree) los tiv thaiv kev tsim cov npuas ntawm qhov kub thiab txias uas yuav ua rau nres nres. Ib lub tuam txhab nres tsheb tau ua kom zoo dua cov mis los tswj qhov ntau npaum li cas ntawm 4-methyl-2-pentnol ntawm 15%, txhim kho qhov kub thiab txias ruaj khov ntawm cov khoom thiab ua tau raws li cov kev cai ntawm high-end automotive braking systems.
2. Lwm cov kua dej tshwj xeeb
Hydraulic roj: nyob rau hauv lub anti- coj hydraulic roj, nws yuav siv tau raws li ib tug antifoam neeg sawv cev los txo cov npuas tsim thaum lub sij hawm ua hauj lwm ntawm hydraulic system thiab tiv thaiv cavitation. Cov kev sim tau pom tias qhov sib ntxiv ntawm 0.05% 4-methyl-2-pennol txhim kho cov kev ua haujlwm ntawm cov roj hydraulic (GB / T 12579-2002) los ntawm 50%, thiab lub kaw lus ua haujlwm zoo dua.
Coolant: Raws li ib tug additive rau antifreeze, nws muaj peev xwm txo lub freezing point ntawm lub coolant (txog -50 degree) thiab nce nws boiling point (txog 130 degree), ua rau nws haum rau huab cua kub ib puag ncig. Ib lub tuam txhab coolant tau nce nws cov khoom xa tawm los ntawm 30% los ntawm kev ntxiv 8% 4-methyl-2-pentnol kom tau raws li cov qauv thoob ntiaj teb rau cov khoom lag luam.
Synthesis ntawm4-methyl-2-pentanol:
Ua ntej, acetone hloov mus rau hauv diacetone cawv los ntawm compression nyob rau hauv lub xub ntiag ntawm alkaline catalyst. Cov catalyst siv yog calcium hydroxide lossis barium hydroxide. Thaum cov catalyst hais me me thiab thaj chaw saum npoo loj, cov kua - cov tshuaj tiv thaiv theem ze ze rau homogeneous cov tshuaj tiv thaiv. Cov txheej txheem tshuaj tiv thaiv tawm cov cua sov, thiab qhov sib npaug ntawm kev hloov pauv yog siab ntawm qhov kub thiab txias. Yog li ntawd, cov acetone nyoos yuav tsum tau precooled thiab cov tshuaj tiv thaiv yuav tsum tau ua ntawm 0-10 degree. Tom qab ntawd, diacetone cawv yog lub cev qhuav dej los tsim isopropylidene acetone. Cov ntsiab lus ntawm ob hom ketone cawv tau txais nyob rau hauv cov txheej txheem yog feem ntau 10-15%, uas yog concentrated mus rau 80% atmospheric distillation, thiab cov unconverted acetone yog sib cais thiab zoo nyob rau tib lub sij hawm. Nyob rau hauv lub xub ntiag ntawm acid catalysts xws li nitric acid, boric acid los yog benzenesulfonic acid, rhuab mus rau 100-200 degree, diacetone cawv yog dehydrated los tsim isopropylidene acetone nrog ib tug conversion ntawm 80-85%. Txawm li cas los xij, diacetone cawv tuaj yeem decomposed rau hauv acetone los ntawm cua sov, yog li acetone hauv lub hauv paus yuav tsum tau rov qab los ntawm lub cev qhuav dej. Cov kauj ruam kawg yog hydrogenation ntawm ob isopropylidene ketones los tsim.
Qhov tseeb, yog tias nickel lossis tooj liab siv los ua catalyst thiab cov xwm txheej rau cov roj theem hydrogenation yog me me nyob rau hauv ib txwm siab, ntau methyl isobutyl ketone yuav tau. Thaum ntsuas kub ntawm 170-210℃thiab molar ratio ntawm hydrogen thiab isopropylidene acetone tau nce, ntau methyl isobutyl methanol, cov khoom ua tiav hydrogenation, yuav tau txais. Feem ntau, qhov sib tov ntawm ob yog tau, thiab lub tshuab nqus tsev distillation yog siv rau distillation sib cais. Nws tseem tuaj yeem tsim los ntawm methyl-isobutyl (methyl) ketone los ntawm nickel catalytic hydrogenation, thiab tom qab ntawd fractionated los ntawm distillation ntauwd kom tau txais cov khoom tiav.
