Taw qhia
Diethyl sebacate. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Diethyl sebacate yog cov kua tsis muaj xim, tsw ntxhiab.
- Cov compound yog insoluble hauv dej tab sis soluble hauv cov organic solvents.
Siv:
- Diethyl sebacate feem ntau yog siv los ua cov kuab tshuaj thiab tau siv dav hauv kev lag luam xws li cov txheej thiab inks.
- Nws kuj yog siv los ua cov txheej txheem thiab cov khoom siv encapsulation los muab huab cua thiab tshuaj tiv thaiv.
- Diethyl sebacate kuj tuaj yeem siv los ua cov khoom siv raw rau cov tshuaj tua kab mob antioxidant thiab hloov pauv polyurethanes.
Txoj kev:
- Diethyl sebacate feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm octanol nrog acetic anhydride.
- React octanol nrog cov kua qaub catalyst (piv txwv li, sulfuric acid) los tsim kom muaj qhov ua kom muaj zog nruab nrab ntawm octanol.
- Tom qab ntawd, acetic anhydride ntxiv thiab esterified los tsim diethyl sebacate.
Cov ntaub ntawv kev nyab xeeb:
- Diethyl sebacate muaj toxicity tsawg nyob rau hauv ib txwm siv.
- Txawm li cas los xij, nws tuaj yeem nkag mus rau tib neeg lub cev los ntawm kev nqus pa, tiv thaiv daim tawv nqaij lossis kev noj, thiab nws cov vapors yuav tsum raug zam thaum siv, kev sib cuag ntawm daim tawv nqaij yuav tsum zam thiab kev noj tshuaj yuav tsum zam.
- Hnav cov cuab yeej tiv thaiv tsim nyog, xws li hnab looj tes thiab tsom iav tiv thaiv, kom muaj cua zoo.
- Cov tawv nqaij los yog khaub ncaws yuav tsum tau ntxuav kom huv si tom qab tus txheej txheem.
- Yog tias noj lossis nqus tau ntau, nrhiav kev kho mob tam sim ntawd.
