Selelekela

Diethyl chloromalonate (e tsejoang hape e le DPC). Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea diethyl chloromalonate:

 

1. Tlhaho:

- Ponahalo: Diethyl chloromalonate ke mokelikeli o se nang 'mala.

- Sollubility: E qhibiliha ka har'a metsoako e mengata ea tlhaho, joalo ka joala, li-ethers le li-hydrocarbon tse nkhang hamonate, empa e qhibiliha hanyane metsing.

- Botsitso: E batla e tsitsitse ho khanya le mocheso, empa e ka hlahisa khase e chefo ea hydrogen chloride mocheso o phahameng kapa malakabe a bulehileng.

 

2. Tšebeliso:

- Joalo ka sehlapi: Diethyl chloromalonate e ka sebelisoa joalo ka sehlapi, haholo ho organic synthesis ho qhaqha le ho etsa metsoako ea lintho tse phelang.

- Kemiso ea lik'hemik'hale: Ke sesebelisoa se sebelisoang hangata bakeng sa ho kopanya li-esters, li-amides le metsoako e meng ea manyolo.

 

3. Mokhoa:

- Diethyl chloromalonate e ka fumanoa ka karabelo ea diethyl malonate ka hydrogen chloride. Maemo a karabelo hangata a mocheso oa kamore, khase ea hydrogen chloride e kenngoa ho diethyl malonate, 'me ho eketsoa motsoako ho khothaletsa karabelo.

- Rection equation: CH3CH2COOCH2CH3 + HCl → ClCH2COOCH2CH3 + H2O

 

4. Litaba tsa Polokeho:

- Diethyl chloromalonate e na le monko o hlabang 'me e ka baka ho teneha letlalong, mahlo le tsela ea ho hema.

- Ke mokelikeli o tukang o hlokang ho bolokoa sebakeng se phodileng, se nang le moea o pholileng le hole le mehloli ea mollo le malakabe a bulehileng.

- Thepa e nepahetseng ea ts'ireletso ea motho joalo ka liatlana, likhalase le liaparo tsa ts'ireletso li lokela ho apesoa nakong ea ho ts'oaroa.
