Okwu mmalite
4,5-Dimethylthiazole bụ ngwakọta organic. Nke a bụ ụfọdụ njirimara ya, ojiji ya, ụzọ nrụpụta ya na ozi nchekwa:
Ogo:
- Ọdịdị: mmiri mmiri na-enweghị agba ma ọ bụ kristal siri ike.
Solubility: Soluble n'ọtụtụ ihe mgbaze organic dị ka alcohols, ethers na ketones.
- Nkwụsi ike: Ọ kwụsiri ike na ụlọ okpomọkụ.
Jiri:
-Enwekwara ike iji ya dị ka onye na-eme ngwa ngwa rọba na onye na-eme ihe na-eme ka ọ dịkwuo mma na-arụ ọrụ nke rọba.
Usoro:
- 4,5-Dimethylthiazole nwere ike ịmepụta site na mmeghachi omume nke dimethyl sodium dithiolate na 2-bromoacetone.
- Mmeghachi omume: 2-bromoacetone + dimethyl dithiolate → 4,5-dimethylthiazole + sodium bromide.
Ozi nchekwa:
- 4,5-Dimethylthiazole bụ ngwakọta organic na ekwesịrị iji usoro njikwa kwesịrị ekwesị zere.
- A na-achọkwa mkpuchi mkpuchi, enyo na uwe mgbe a na-eji ya.
- Zere ikuru uzuoku ya ma hụ na ọ na-arụ ọrụ na gburugburu ikuku ikuku.
- Ọ bụrụ na ọ na-efesa n'anya na mberede, were ọtụtụ mmiri sachaa ozugbo wee chọọ nlekọta ahụike ozugbo.
- Chekwaa 4,5-dimethylthiazole n'ebe dị jụụ, kpọrọ nkụ na-adịghị na oxidants na acid siri ike.
