Nhanganyaya

Diethyl chloromalonate (inozivikanwawo seDPC). Inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza diethyl chloromalonate:

 

1. Zvisikwa:

-Kuonekwa: Diethyl chloromalonate imvura isina ruvara.

- Solubility: Inonyungudika mune zvakawanda organic zvinonyungudutsa, zvakaita sedoro, ether, uye anonhuwirira hydrocarbons, asi zvishoma kunyungudika mumvura.

- Kugadzikana: Yakagadzikana kuchiedza nekupisa, asi inogona kuburitsa muchetura hydrogen chloride gasi pakupisa kwakanyanya kana mirazvo yakavhurika.

 

2. Kushandisa:

- Sezvinonyungudutsa: Diethyl chloromalonate inogona kushandiswa sechinhu chinonyungudutsa, kunyanya mune organic synthesis kunyungudutsa uye kuita organic komisheni.

-Kemikari synthesis: Inowanzo shandiswa reagent yekubatanidza esters, amides, uye mamwe organic komisheni.

 

3. Nzira:

- Diethyl chloromalonate inogona kuwanikwa nekuita kwediethyl malonate ine hydrogen chloride. Mamiriro ekuita anowanzo pane tembiricha yekamuri, hydrogen chloride gasi inounzwa mudiethyl malonate, uye catalyst inowedzerwa kukurudzira maitiro.

- Reaction equation: CH3CH2COOCH2CH3 + HCl → ClCH2COOCH2CH3 + H2O

 

4. Ruzivo Rwekuchengetedza:

- Diethyl chloromalonate ine kunhuhwirira kwakanyanya uye inogona kukonzera kutsamwa paganda, maziso, uye nzira yekufema.

-Imvura inobvira moto inoda kuchengetwa munzvimbo inotonhorera, ine mhepo inofefetera uye kure nenzvimbo dzemoto nemirazvo yakavhurika.

- Midziyo yekuzvidzivirira yakafanira senge magirovhosi, magirazi uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa panguva yekubata.
