Mawu Oyamba
Diethyl chloromalonate (yomwe imadziwikanso kuti DPC). Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha diethyl chloromalonate:
1. Chilengedwe:
- Maonekedwe: Diethyl chloromalonate ndi madzi opanda mtundu.
- Kusungunuka: Amasungunuka mu zosungunulira zambiri, monga ma alcohols, ethers, ndi ma hydrocarbon onunkhira, koma amasungunuka pang'ono m'madzi.
- Kukhazikika: Imakhala yokhazikika poyaka komanso kutentha, koma imatha kutulutsa mpweya wapoizoni wa hydrogen chloride pakatentha kwambiri kapena kuyaka moto.
2. Kagwiritsidwe:
- Monga zosungunulira: Diethyl chloromalonate itha kugwiritsidwa ntchito ngati zosungunulira, makamaka mu kaphatikizidwe ka organic kuti asungunuke ndikuchitapo kanthu pazachilengedwe.
- Chemical kaphatikizidwe: Ndi reagent yomwe imagwiritsidwa ntchito kwambiri popanga ma esters, ma amides, ndi ma organic compounds.
3. Njira:
- Diethyl chloromalonate ikhoza kupezedwa ndi zochita za diethyl malonate ndi hydrogen chloride. Zomwe zimachitika nthawi zambiri zimakhala kutentha, mpweya wa hydrogen chloride umalowetsedwa mu diethyl malonate, ndipo chothandizira chimawonjezeredwa kuti chilimbikitse zomwe zikuchitika.
- Mayankho equation: CH3CH2COOCH2CH3 + HCl → ClCH2COOCH2CH3 + H2O
4. Zambiri Zachitetezo:
- Diethyl chloromalonate ili ndi fungo loyipa ndipo imatha kuyambitsa kuyabwa pakhungu, maso, komanso kupuma.
- Ndi madzi oyaka omwe amayenera kusungidwa pamalo ozizira, mpweya wabwino komanso kutali ndi zoyatsira moto ndi malawi otseguka.
- Zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zovala zodzitetezera ziyenera kuvalidwa pogwira.
