Taw qhia
Butyl isobutyrate. Nws cov khoom yog raws li nram no:
Lub cev muaj zog: Butyl isobutyrate yog cov kua tsis muaj xim nrog cov txiv hmab txiv ntoo saj ntawm chav sov.
Cov khoom siv tshuaj: butyl isobutyrate muaj cov solubility zoo thiab solubility zoo hauv cov kuab tshuaj organic. Nws muaj cov reactivity ntawm esters thiab tuaj yeem hydrolyzed rau hauv isobutyric acid thiab butanol.
Kev Siv: Butyl isobutyrate yog dav siv hauv kev lag luam thiab chaw kuaj tshuaj. Nws tuaj yeem siv los ua tus neeg sawv cev tsis muaj zog hauv cov kuab tshuaj, txheej thiab inks, thiab ua cov yas rau cov yas thiab cov resins.
Txoj kev npaj: Feem ntau, butyl isobutyrate yog npaj los ntawm esterification cov tshuaj tiv thaiv ntawm isobutanol thiab butyric acid nyob rau hauv acid-catalyzed tej yam kev mob. Cov tshuaj tiv thaiv kub yog feem ntau 120-140 ° C, thiab lub sijhawm tshuaj tiv thaiv yog li 3-4 teev.
Nws tuaj yeem ua rau khaus ntawm qhov muag thiab tawv nqaij thiab yuav tsum tau yaug nrog dej ntau tam sim ntawd tom qab sib cuag. Thaum lub sijhawm ua haujlwm, qhov cua zoo yuav tsum tau ua kom ntseeg tau. Nws yuav tsum khaws cia kom deb ntawm cov menyuam yaus thiab cov khoom siv hluav taws xob thiab khaws cia rau hauv lub thawv airtight. Thaum tuav thiab pov tseg, nws yuav tsum tau ua raws li cov kev cai hauv zos.
