Intshayelelo
I-Diethyl chloromalonate (ekwaziwa njenge-DPC). Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-diethyl chloromalonate:
1. Indalo:
- Imbonakalo: I-Diethyl chloromalonate lulwelo olungenambala.
- Ukunyibilika: Inyibilika kuninzi lwezinyibilikisi zendalo, ezinje ngealkoholi, iiether, kunye neehydrocarbons ezinevumba elimnandi, kodwa zinyibilika kancinane emanzini.
- Uzinzo: Uzinzile ekukhanyeni nasebushushu, kodwa unokuvelisa igesi eyityhefu yehydrogen chloride kumaqondo obushushu aphezulu okanye amadangatye avulekileyo.
2. Ukusetyenziswa:
- Njenge-solvent: I-Diethyl chloromalonate ingasetyenziswa njenge-solvent, ngakumbi kwi-organic synthesis ukuze inyibilike kwaye iphendule i-organic compounds.
- I-Chemical synthesis: Yinto esetyenziswa ngokuqhelekileyo ukudibanisa i-esters, i-amides, kunye nezinye izinto eziphilayo.
3. Indlela:
- I-Diethyl chloromalonate inokufumaneka ngokusabela kwe-diethyl malonate kunye ne-hydrogen chloride. Iimeko zokusabela ziqhelekileyo kwiqondo lokushisa, igesi ye-hydrogen chloride ifakwe kwi-diethyl malonate, kwaye i-catalyst yongezwa ukukhuthaza ukusabela.
-Ireaction equation: CH3CH2COOCH2CH3 + HCl → ClCH2COOCH2CH3 + H2O
4. Ulwazi ngoKhuseleko:
I-Diethyl chloromalonate inevumba elibi kwaye inokubangela ukucaphuka eluswini, emehlweni, nakwindlela yokuphefumla.
- Lulwelo olunokutsha olufuna ukugcinwa kwindawo epholileyo, nengena umoya kwaye kude nemithombo yomlilo kunye namadangatye avulekileyo.
- Izixhobo ezifanelekileyo zokuzikhusela ezinje ngeeglavu, iiglasi, kunye nempahla yokukhusela kufuneka zinxitywe ngexesha lokuphatha.
