Okwu mmalite
Diethyl chloromalonate (nke a makwaara dị ka DPC). Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke diethyl chloromalonate:
1. Eke:
- Ọdịdị: Diethyl chloromalonate bụ mmiri mmiri na-enweghị agba.
- Solubility: Ọ na-agbaze n'ọtụtụ ihe mgbaze organic, dị ka alcohols, ethers, na aromatic hydrocarbons, mana ntakịrị soluble na mmiri.
- Nkwụsi ike: Ọ kwụsiri ike na ọkụ na ikpo ọkụ, mana ọ nwere ike imepụta gas hydrogen chloride na-egbu egbu na oke okpomọkụ ma ọ bụ ọkụ mepere emepe.
2. Ojiji:
- Dị ka ihe mgbaze: Diethyl chloromalonate nwere ike iji dị ka ihe mgbaze, karịsịa na organic synthesis ka igbari na meghachi omume organic ogige.
- Ngwakọta kemịkalụ: Ọ bụ reagent a na-ejikarị eme ihe maka njikọ nke esters, amides na ogige ndị ọzọ.
3. Usoro:
- Enwere ike nweta Diethyl chloromalonate site na mmeghachi omume nke diethyl malonate na hydrogen chloride. Ọnọdụ mmeghachi omume na-adịkarị n'ime ụlọ okpomọkụ, hydrogen chloride gas na-abanye n'ime diethyl malonate, na-agbakwunye ihe na-akpali akpali iji kwalite mmeghachi omume ahụ.
- Ndekọ mmeghachi omume: CH3CH2COOCH2CH3 + HCl → ClCH2COOCH2CH3 + H2O
4. Ozi nchekwa:
- Diethyl chloromalonate nwere isi na-esighi ike ma nwee ike ịkpasu akpụkpọ ahụ, anya, na akụkụ iku ume.
- Ọ bụ mmiri mmiri na-ere ọkụ nke kwesịrị ịchekwa ya n'ebe dị jụụ, nke ikuku na-ekpo ọkụ ma pụọ na isi ọkụ na ọkụ na-emeghe.
-Ekwesịrị iyi akụrụngwa nchekwa kwesịrị ekwesị dị ka uwe, enyo na uwe nchebe n'oge ejikwa ya.
