Qhov sib txawv tseem ceeb ntawm butyl cellosolve thiab butyl carbitol yog tias butyl cellosolve muaj ib pab pawg ua haujlwm ether, qhov butyl carbitol muaj ob pawg ua haujlwm ether.
Butyl cellosolve thiab butyl carbitol yog cov kuab tshuaj tseem ceeb uas tuaj yeem txheeb xyuas tau tias yog glycol ethers. Lawv muaj cov tshuaj sib txawv thiab siv.
Butyl Cellosolve yog dab tsi?
Butyl cellosolve lossis 2-butoxyethanol yog cov organic compound uas muaj cov tshuaj formula CH3CH2CH2CH3-O-C2H4OH. Nws tshwm sim raws li cov kua ntshiab, tsis muaj xim uas muaj cov ntxhiab tsw qab, zoo li ether. Cov tshuaj no yog muab los ntawm tsev neeg ntawm glycol ethers. Peb tuaj yeem txheeb xyuas nws li butyl ether ntawm ethylene glycol.
Daim duab 01: Cov Qauv Tshuaj ntawm Butyl Cellosolve
Qhov no yog cov kuab tshuaj tsis zoo thiab pheej yig uas muaj txiaj ntsig zoo hauv ntau yam khoom siv hauv tsev thiab kev lag luam vim muaj cov khoom siv surfactant nws muaj. Txawm li cas los xij, butyl cellosolve yog suav tias yog ua pa ua pa uas tuaj yeem ua rau mob hnyav. Ntxiv mus, qhov sib xyaw no yog miscible nrog dej thiab nyob rau hauv feem ntau cov organic solvents ib yam nkaus.
Feem ntau, peb tuaj yeem npaj butyl cellosolve hauv ob txoj hauv kev: (1) ethoxylation cov tshuaj tiv thaiv ntawm butanol thiab ethylene oxide nyob rau hauv muaj cov catalyst, (2) etherification ntawm butanol nrog 2-chloroethanol. Ntxiv mus, peb tuaj yeem tau txais qhov sib xyaw no hauv chav kuaj los ntawm kev ua haujlwm ntawm lub nplhaib qhib ntawm 2-propyl-1, 3-dioxloane nyob rau hauv muaj boron trichloride.
Thaum xav txog kev siv butyl cellosolve, nws yog qhov tseem ceeb ua cov kuab tshuaj rau cov xim thiab cov txheej txheem saum npoo, raws li cov khoom siv hauv cov khoom siv tu thiab cov ntaub ntawv, acrylic resin formulations, asph alt tso cov neeg ua haujlwm, cov duab thaij duab daws teeb meem, ua npuas dej tua hluav taws, tawv tiv thaiv, roj spill dispersants, degreaser daim ntaub ntawv, thiab lwm yam.
Butyl Carbitol yog dab tsi?
Butyl carbitol lossis DEG monobutyl ether yog cov organic compound uas muaj cov tshuaj formula C8H18O3. Nws zoo nkaus li cov kua tsis muaj xim, ntshiab uas yog soluble hauv dej, ethanol, ethyl ether, thiab acetone.
Daim duab 02: Cov Qauv Tshuaj ntawm Butyl Carbitol
Nws tuaj yeem txheeb xyuas tau tias yog ib qho ntawm ob peb glycol ether solvents. Nws muaj ib tug me ntsis tsw thiab ib tug kub boiling point. Butyl carbitol tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv ntawm ethylene oxide thiab n-butanol nrog alkali catalyst.
Daim duab 03: Ib Lub raj mis ntawm Butyl Carbitol
Butyl carbitol tuaj yeem siv los ua cov kuab tshuaj rau ntau yam khoom xws li xim, kua roj vanish, tshuaj ntxuav tsev, thiab tshuaj brewing; nyob rau hauv cov khoom siv tshuaj tua kab, nws ua raws li cov khoom siv tsis muaj zog ua lub deactivator rau kev tsim ua ntej cov qoob loo tawm ntawm cov av thiab ua ib qho stabilizer. Tsis tas li ntawd, nws yog ib qho tseem ceeb nruab nrab rau kev sib txuas ntawm diethylene glycol monobutyl ether acetate.
Qhov txawv ntawm Butyl Cellosolve thiab Butyl Carbitol yog dab tsi?
Muaj cov tshuaj sib txawv ntawm butyl cellosolve thiab butyl carbitol, uas ua rau lawv muaj cov ntawv thov sib txawv. Qhov sib txawv tseem ceeb ntawm butyl cellosolve thiab butyl carbitol yog tias butyl cellosolve muaj ib pab pawg ua haujlwm ether thaum butyl carbitol muaj ob pawg ether ua haujlwm.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm butyl cellosolve thiab butyl carbitol hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary - Butyl Cellosolve vs Butyl Carbitol
Butyl cellosolve lossis 2-butoxyethanol yog cov organic compound uas muaj cov tshuaj formula CH3CH2CH2CH3-O-C2H4OH. Lub caij no, butyl carbitol lossis DEG monobutyl ether yog cov organic compound uas muaj cov tshuaj formula C8H18O3. Qhov sib txawv tseem ceeb ntawm butyl cellosolve thiab butyl carbitol yog tias butyl cellosolve muaj ib pab pawg ua haujlwm ether, qhov butyl carbitol muaj ob pawg ua haujlwm ether.
