Isobutyl isobutyrate muaj ntau yam tshuaj lom neeg yam ntxwv. Cov qauv tshwj xeeb no muab isobutyl isobutyrate nws cov khoom sib txawv thiab ntau yam kev siv.
Isobutyl isobutyrate yog dab tsi?
Isobutyl isobutyrate feem ntau yog siv rau hauv kev npaj cov tshuaj tsw qab thiab flavorings, thiab yog ib feem tseem ceeb ntawm pineapple tsw. Isobutyl isobutyrate tsw zoo li cas?
Nws muaj pineapple, txiv hmab txiv ntoo, los yog ether -zoo li aroma. Nws tuaj yeem siv los ua zaub mov flavoring, ntxiv rau txiv hmab txiv ntoo flavors, seasonings, thiab haus luam yeeb flavorings.
Nws kuj yog ib qho zoo heev organic solvent, qhuav hmoov tshem tawm, thiab extractive distillation pab.
Vim tias nws yog qhov tseem ceeb tsis muaj teeb meem rau tib neeg thiab tsiaj txhu thiab tsis ua rau muaj kuab paug ib puag ncig, nws yog cov khoom ntsuab zoo. Nrog nce kev tiv thaiv ib puag ncig, daim ntawv thov ntawm isobutyl isobutyrate tau dhau los ua ntau dua.
Lub cev muaj zog ntawm Isobutyl Isobutyrate
Isobutyl isobutyrateyog ib qho flammable, tsis muaj xim, pob tshab kua. Nws qhov kub kub yog 148.6 degree, melting point yog -80.6 degree, flash point yog 37 degree, txheeb ze ntom (D204) yog 0.874, thiab refractive index yog 1.398.
Nws yog insoluble hauv dej tab sis soluble hauv cawv, ethers, thiab ketones. Lub vapor siab yog dab tsi? Lub vapor siab ntawm isobutyl isobutyrate yog 1 mmHg (39.9 degree).
Kev Ntsuam Xyuas Cov Qauv
Nws yog tus cwj pwm los ntawm nws cov qauv molecular, suav nrog pawg ester hauv nruab nrab (C=OOC) thiab ob pawg butyl zoo tib yam [(CH3)2CH-].
Dab tsi ua haujlwm pab pawg isobutyl isobutyrate muaj? Nws yog carboxylic acid ester organic compound.
Carboxylic acid esters yog derivatives ntawm carboxylic acids, nyob rau hauv uas cov pa roj carbon atom nyob rau hauv cov carboxylic acid pawg yog txuas nrog ib tug alkyl los yog aromatic pab pawg neeg los ntawm ib tug oxygen atom (ua ib pawg ester). Cov qauv tshwj xeeb no ua rau nws tshwj xeeb:
(1) Lub xub ntiag ntawm pawg ester tso cai rau isobutyl isobutyrate koom nrog hydrolysis thiab esterification cov tshuaj tiv thaiv, thiab txhim kho nws cov kev hloov pauv tshuaj lom neeg.
(2) Kev sib xyaw ua ke ntawm ob pawg butyl sib txawv tsim cov qauv ntawm cov qauv molecular, uas cuam tshuam rau lub cev lub cev xws li melting point thiab boiling point.
Isobutyl isobutyrate, raws li cov kuab tshuaj organic, muaj ntau yam kev siv tshwj xeeb:
Hloov rau xylene: Hauv cov txheej txheem yas, isobutyl isobutyrate tuaj yeem hloov xylene, tiv thaiv qhov tshwm sim "hlawv". Qhov no yog vim hais tias cov yas sib txawv yog rhiab heev rau cov kuab tshuaj muaj zog, uas tuaj yeem yooj yim ua rau kev sib cais ntawm txheej los ntawm substrate.
Siv rau hauv cov ntoo coatings: Nws ua tau zoo nyob rau hauv cov ntoo coatings, muab cov pigment dispersion zoo heev.
Hlau flake xim formulations: Nyob rau hauv cov xim hlau flakes, nws tiv thaiv hlau pigments, tiv thaiv oxidation thiab discoloration ntawm kub thiab nyiaj hmoov.
Tsawg-volatility hnyav: Isobutyl isobutyrate yog qis-volatility hnyav, haum rau polyurethane txheej, pab txhim kho qhov zoo thiab kav ntev ntawm txheej.
Cov kuab tshuaj Retarder: Vim nws cov dej tsis zoo, isobutyl isobutyrate kuj yog cov kuab tshuaj retarder zoo heev, haum rau cov dej noo- cov coatings rhiab heev.
