Okwu mmalite
pent-4-ynoic acid, nke a makwaara dị ka pent-4-ynoic acid, usoro kemịkalụ C5H6O2. Ihe na-esonụ bụ mmalite nke ọdịdị, ojiji, nhazi na ozi nchekwa nke pent-4-ynoic acid:
Ọdịdị:
- pent-4-ynoic acid bụ mmiri mmiri na-enweghị agba nke nwere isi ísì.
Obere ihe dị n'ime ya bụ 102.1g / mol.
Jiri:
- pent-4-ynoic acid bụ etiti dị mkpa na njikọ kemịkalụ ma jiri ya dozie ogige ndị ọzọ.
- Enwere ike iji ya mee ihe maka mmeghachi omume carbonylation, mmeghachi omume condensation na mmeghachi omume esterification na mmeghachi omume njikọ organic.
- pent-4-ynoic acid nwekwara ike iji na nkwadebe nke ọgwụ, fragrances na agba.
Ụzọ nkwadebe:
Enwere ike nweta nkwadebe nke pent-4-ynoic acid site na 1-chloropentyne na acid hydrolysis. Nke mbụ, 1-chloropentyne na-emeghachi omume na mmiri iji nye aldehyde ma ọ bụ ketone kwekọrọ, mgbe ahụ, aldehyde ma ọ bụ ketone na-agbanwe na pent-4-ynoic acid site na mmeghachi omume oxidation.
Ozi nchekwa:
- pent-4-ynoic acid bụ kemịkalụ na-akpasu iwe nke nwere ike ime ka mgbakasị ahụ na mbufụt na kọntaktị na akpụkpọ ahụ na anya.
- Yiri gloves nchebe, iko, na uwe ụlọ nyocha mgbe ị na-eji pent-4-ynoic acid.
-Ọ bụrụ na ị na-akpakọrịta na akpụkpọ ahụ ma ọ bụ anya, jiri mmiri buru ibu sachaa ozugbo wee chọọ nlekọta ahụike.
- Zere kọntaktị na oxidants, acid siri ike na ntọala siri ike n'oge nchekwa na iji zere mmeghachi omume dị ize ndụ.
Biko mara na tupu iji kemịkal ọ bụla, ị ga-agụrịrị akwụkwọ nchekwa data (MSDS) nke kemịkalụ nke ọma wee soro usoro arụ ọrụ ziri ezi yana usoro arụ ọrụ adịghị mma.
