Okwu mmalite
3-Pyridine formaldehyde. Ihe na-esonụ bụ mmalite nke akụrụngwa, ojiji, ụzọ nkwadebe na ozi nchekwa nke 3-pyridine formaldehyde:
Ogo:
- Ọdịdị: 3-pyridine formaldehyde bụ mmiri mmiri na-enweghị agba ma ọ bụ kristal ọcha.
- Solubility: Ọ na-agbaze n'ọtụtụ ihe mgbaze organic dị ka ethanol na chloroform.
Jiri:
- Iji sịntetik: 3-pyridine formaldehyde na-ejikarị eme ihe dị ka ihe na-emepụta ihe, ihe dị n'etiti n'ime njikọ organic na ihe eji eme ihe.
Usoro:
- 3-Pyridine formaldehyde nwere ike ịkwado ya site na N-oxidation nke pyridine. Usoro njikọ nke a na-ejikarị eme ihe bụ imeghachi pyridine na onye na-eme ihe na-eme ka ọ na-eme ihe dị ka benzoyl peroxide ma ọ bụ hydrogen peroxide iji mepụta 3-pyridine formaldehyde.
Ozi nchekwa:
- Ekwesịrị iburu n'uche nchekwa nchekwa ndị a mgbe ị na-eji na ịchekwa 3-pyridine formaldehyde:
- Zere kọntaktị na akpụkpọ ahụ ma zere ikuru ume ma ọ bụ itinye ihe mejupụtara ya.
- Yiri gloves kemịkal na anya nchebe mgbe ị na-eji.
- Jiri ya na mpaghara ikuku nke ọma ma zere ọkụ ma ọ bụ okpomọkụ dị elu.
- Mgbe a na-echekwa ya, a ga-edobe ya nke ọma, pụọ na isi ọkụ na ihe ndị na-ere ọkụ.
- Mgbe ị na-eji ma na-ejikwa 3-pyridine formaldehyde, soro usoro nchekwa dị mkpa na usoro nchebe onwe onye.
