Mawu Oyamba
2-ETHOXY-5-NITROPYRIDINE ndi mankhwala omwe ali ndi mankhwala C8H8N2O3.
Chilengedwe:
2-ETHOXY-5-NITROPYRIDINE ndi kristalo wachikasu wolimba ndi fungo losiyana. Ili ndi malo osungunuka pafupifupi 56-58 madigiri Celsius ndi malo owira pafupifupi 297-298 madigiri Celsius. Ndi insoluble m'madzi pa kutentha kwabwino, koma sungunuka mu zosungunulira za organic monga mowa, ether, etc. Ndi gulu losakhazikika lomwe limawola mosavuta pansi pa kuwala, kutentha ndi kutentha.
Gwiritsani ntchito:
2-ETHOXY-5-NITROPYRIDINE ingagwiritsidwe ntchito ngati yofunika kwambiri pakati pa organic synthesis, yomwe imagwiritsidwa ntchito kwambiri popanga mankhwala, mankhwala, utoto ndi zina. Monga multifunctional pawiri, angagwiritsidwe ntchito popanga mankhwala ena, monga mankhwala, mankhwala ndi utoto.
Njira:
2-ETHOXY-5-NITROPYRIDINE ili ndi njira zambiri zokonzekera, imodzi yomwe imagwiritsidwa ntchito pochita 5-chloropyridine ndi mowa wa ethyl pansi pa zinthu zamchere. Masitepe ophatikizika amafunikira mwatsatanetsatane ntchito yoyesera komanso chidziwitso chamankhwala, chonde chitani momwe kaphatikizidwira m'malo a labotale.
Zambiri Zachitetezo:
2-ETHOXY-5-NITROPYRIDINE ingayambitse kupsa mtima pamene ikukhudzana ndi khungu ndi maso, choncho m'pofunika kuvala zipangizo zoyenera zodzitetezera panthawi yogwira ntchito ndikugwira ntchito. Panthawi imodzimodziyo, chigawochi chimakhala cholimba choyaka moto ndipo chiyenera kusungidwa kutali ndi moto ndi kutentha kwakukulu kuti zisawonongeke mpweya woipa ndi nthunzi. Posunga ndi kusamalira, yang'anani njira zoyenera zotetezera ndikuzisunga m'matumba osindikizidwa. Pakachitika ngozi, chonde tengani njira zoyenera zadzidzidzi nthawi yomweyo ndikupempha thandizo lachipatala.
