Okwu mmalite
Valeric anhydride bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke valeric anhydride:
Ogo:
- Valeric anhydride bụ mmiri na-enweghị agba, nke nwere isi na-esi ísì ụtọ.
- Ọ na-eji mmiri emeghachi omume iji mepụta ngwakọta nke valeric acid na valeric anhydride.
Jiri:
A na-ejikarị Valeric anhydride mee ihe dị ka reagent na etiti na njikọ organic.
- Enwere ike iji ya kwadebe ogige ndị nwere otu ọrụ dị iche iche, dị ka ethyl acetate, anhydrides, na amides.
- A pụkwara iji Valeric anhydride mee ihe na njikọ nke pesticides na fragrances.
Usoro:
Valeric anhydride na-emekarị site na mmeghachi omume nke valeric acid na anhydride (dịka acetic anhydride).
- Enwere ike ime ọnọdụ mmeghachi omume na okpomọkụ ụlọ ma ọ bụ kpoo ọkụ n'okpuru nchebe nke gas inert.
Ozi nchekwa:
- Valeric anhydride na-akpasu iwe ma na-emebi emebi, na-ezere ịkpọtụrụ akpụkpọ ahụ na anya, ma hụ na ị na-arụ ọrụ na mpaghara ikuku dị mma.
- N'oge njikwa na nchekwa, zere kọntaktị na oxidants ma ọ bụ acid siri ike na ntọala iji zere mmeghachi omume dị ize ndụ.
- Soro usoro njikwa mma maka kemịkalụ wee kwadebe onwe gị ngwa nchebe kwesịrị ekwesị dị ka uwe ụlọ nyocha, ugogbe nchekwa, wdg.
