Okwu mmalite
2,3-dimethyl-2-butene (DMB) bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke ọdịdị ya, ojiji ya, ụzọ mmepụta ya na ozi nchekwa:
Ogo:
Ọdịdị: DMB bụ mmiri mmiri na-enweghị agba.
Solubility: Ọ na-agbaze n'ọtụtụ ihe mgbaze organic dị ka ethanol, ethers, na hydrocarbons.
Njupụta: Njupụta ya dị ihe dịka 0.68 g/cm³.
Nsi: DMB adịchaghị egbu egbu, mana oke ikpughe nwere ike ịkpasu iwe anya na mgbakasị anụ ahụ.
Jiri:
Ngwakọta kemịkalụ: A na-ejikarị DMB eme ihe na njikọ organic dị ka ihe mgbaze, etiti, ma ọ bụ ihe mkpali.
Ụlọ ọrụ mmanụ ala: A na-ejikwa DMB dị ka kemịkalụ ngwa dị mkpa na nhazi mmanụ ala jute na usoro petrochemical.
Usoro:
A na-akwadokarị DMB site na alkylation nke methylbenzene na propylene. Usoro ndị a kapịrị ọnụ gụnyere imeghachi omume methylbenzene na propylene na okpomọkụ na nrụgide kwesịrị ekwesị n'ihu ihe na-eme ka ọ na-emepụta DMB.
Ozi nchekwa:
Dị ka ihe mgbaze organic, DMB na-agbanwe agbanwe. N'oge a na-eji ya eme ihe, ọ dị mkpa ịnọgide na-enwe ezigbo ikuku ma zere ikpughe oke.
Nwere ike ịkpasu iwe mgbe ị na-akpakọrịta akpụkpọ na anya. Ekwesịrị izere kọntaktị ogologo oge, iku ume, ma ọ bụ ilo.
Mgbe ị na-echekwa ma na-ejikwa DMB, mmeghachi omume nwere oxidants siri ike na acid siri ike kwesịrị izere.
Ọ bụrụ na ị na-akpakọrịta na ihe a, ozugbo kpochaa ebe akpụkpọ ahụ ma ọ bụ anya na-emerụ emerụ na mmiri buru ibu ma chọọ nlekọta ahụike.
