Taw qhia
Ethyl allylenate hmoov. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm ethyl allylate:
Zoo:
- Ethyl allyl proponate yog cov kua uas muaj ntxhiab tsw, soluble hauv ntau yam organic solvents xws li cawv, ethers, thiab lwm yam, tab sis insoluble hauv dej.
- Ethyl allyl proponate muaj kev ruaj ntseg zoo, tab sis polymerization tshwm sim hauv tshav ntuj.
Siv:
- Ethyl allyl propionate yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis, uas tuaj yeem siv rau hauv kev tsim cov khoom siv tshuaj xws li txuj lom, plastics, thiab dyes.
- Nws tseem tuaj yeem siv los ua cov kuab tshuaj hauv kev lag luam xws li txheej, inks, kua nplaum, thiab lwm yam.
- Ethyl allyl kuj tuaj yeem siv rau hauv kev npaj cov resins, lubricants thiab plasticizers.
Txoj kev:
- Ethyl allyl feem ntau yog tsim los ntawm cov tshuaj tiv thaiv ntawm ethylene nrog acrylic acid, uas yog ces anhydrated rau ethyl allylate.
- Hauv kev lag luam, catalysts xws li sulfuric acid feem ntau yog siv los pab txhawb cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
- Ethyl allyl yog cov kua hluav taws xob thiab yuav tsum zam kom tsis txhob muaj kev sib cuag nrog cov nplaim taws qhib, qhov kub thiab txias, thiab oxidizing cov neeg ua haujlwm.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv thaum siv.
- Tsis txhob sib cuag nrog daim tawv nqaij, qhov muag thiab ua pa ntawm ethyl allylenate, yaug tam sim ntawd nrog dej kom ntau thiab nrhiav kev kho mob yog tias ua tau.
- Cov huab cua zoo yuav tsum tau noj thaum khaws cia thiab siv ethyl allylenate.
- Thaum pov tseg cov pov tseg, ua raws li cov cai hauv cheeb tsam ib puag ncig.
