Ubwino:
- 2,4-Dichloropyrimidine ndi kristalo wopanda mtundu wokhala ndi fungo loyipa.
- Imakhala ndi kusungunuka kochepa m'madzi komanso kusungunuka kwakukulu mu zosungunulira za organic.
Gwiritsani ntchito:
- 2,4-Dichloropyrimidine ndi mankhwala omwe amagwiritsidwa ntchito kwambiri pothana ndi udzu mu mbewu.
Njira:
- 2,4-Dichloropyrimidine ikhoza kukonzedwa pochita pyrimidine ndi mpweya wa chlorine. Sungunulani pyrimidines mu ferrous chloride ndi kutentha kwa kutentha koyenera. Kenako, chlorination reaction ikuchitika poyambitsa mpweya wa chlorine mumayendedwe. Zomwe zimapangidwira zimapezedwa kudzera muzitsulo za crystallization ndi kuyeretsa.
Zambiri Zachitetezo:
- 2,4-Dichloropyrimidine ndi chinthu chokwiyitsa chomwe chingathe kuwononga maso, khungu, ndi kupuma.
- Mukamagwiritsa ntchito 2,4-dichloropyrimidine, valani magolovesi oteteza, magalasi, ndi masks kuti mukhale ndi mpweya wabwino.
- Mukangokumana ndi 2,4-dichloropyrimidine, sambani malo omwe akhudzidwa ndi madzi ambiri ndikupita kuchipatala mwachangu.
- Posunga ndikugwira, kukhudzana ndi okosijeni ndi ma asidi amphamvu kuyenera kupewedwa kuti mupewe zoopsa.
