Taw qhia
Diethyl chloromalonate (tseem hu ua DPC). Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm diethyl chloromalonate:
1. Xwm:
- Cov tsos mob: Diethyl chloromalonate yog cov kua tsis muaj xim.
- Solubility: Nws yog soluble nyob rau hauv feem ntau cov organic solvents, xws li cawv, ethers, thiab aromatic hydrocarbons, tab sis me ntsis soluble nyob rau hauv dej.
- Kev ruaj ntseg: Nws yog qhov ruaj khov rau lub teeb thiab cua sov, tab sis tuaj yeem tsim cov pa roj hydrogen chloride ntawm qhov kub thiab txias los yog qhib nplaim taws.
2. Kev siv:
- Raws li cov kuab tshuaj: Diethyl chloromalonate tuaj yeem siv los ua cov kuab tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov organic synthesis kom yaj thiab ua rau cov organic tebchaw.
- Chemical synthesis: Nws yog ib qho reagent feem ntau siv rau cov synthesis ntawm esters, amides, thiab lwm yam organic compounds.
3. Txoj kev:
- Diethyl chloromalonate tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm diethyl malonate nrog hydrogen chloride. Cov tshuaj tiv thaiv kab mob feem ntau yog nyob rau hauv chav tsev kub, hydrogen chloride gas yog nkag mus rau hauv diethyl malonate, thiab ib tug catalyst ntxiv los txhawb cov tshuaj tiv thaiv.
- Reaction equation: CH3CH2COOCH2CH3 + HCl → ClCH2COOCH2CH3 + H2O
4. Cov ntaub ntawv kev nyab xeeb:
- Diethyl chloromalonate muaj ntxhiab tsw thiab tuaj yeem ua rau khaus tawv nqaij, qhov muag, thiab ua pa.
- Nws yog cov kua nplaum uas yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua zoo thiab deb ntawm qhov hluav taws kub thiab qhib nplaim taws.
- Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum tuav.
