Isingeniso
i-pent-4-ynoic acid, eyaziwa nangokuthi i-pent-4-ynoic acid, ifomula yamakhemikhali C5H6O2. Okulandelayo yisingeniso semvelo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha lwe-pent-4-ynoic acid:
Imvelo:
I-pent-4-ynoic acid iwuketshezi olungenambala olunephunga elimnandi.
-Isisindo sayo samangqamuzana singu-102.1g/mol.
Sebenzisa:
- i-pent-4-ynoic acid iyingxenye ebalulekile ekuhlanganiseni kwamakhemikhali futhi isetshenziselwa ukulungisa ezinye izinhlanganisela.
-Ingasetshenziselwa ukusabela kwe-carbonylation, ukusabela kwe-condensation kanye nokusabela kwe-esterification ku-organic synthesis reaction.
- i-pent-4-ynoic acid ingasetshenziswa futhi ekulungiseleleni izidakamizwa, amakha namadayi.
Indlela Yokulungiselela:
-Ukulungiswa kwe-pent-4-ynoic acid kungafinyelelwa nge-1-chloropentyne ne-acid hydrolysis. Okokuqala, i-1-chloropentyne iphendulwa ngamanzi ukuze inikeze i-aldehyde ehambisanayo noma i-ketone, bese i-aldehyde noma i-ketone iguqulelwa ku-pent-4-ynoic acid ngokusabela kwe-oxidation.
Ulwazi Lokuphepha:
- i-pent-4-ynoic acid iyikhemikhali ecasulayo engabangela ukucasuka nokuvuvukala ekuthintaneni nesikhumba namehlo.
-Gqoka amagilavu okuzivikela, izibuko, nezimpahla zaselabhorethri uma usebenzisa i-pent-4-ynoic acid.
-Uma uthinta isikhumba noma amehlo, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
-Gwema ukuthintana nama-oxidants, ama-asidi aqinile nezisekelo eziqinile ngesikhathi sokugcina futhi usebenzise ukugwema ukusabela okuyingozi.
Sicela uqaphele ukuthi ngaphambi kokusebenzisa noma yiliphi ikhemikhali, kufanele ufunde i-safety data sheet (MSDS) yekhemikhali ngokucophelela futhi ulandele izindlela zokusebenza ezifanele kanye nezinqubo zokusebenza eziphephile.
