i-methyl pent-4-ynoate (CAS# 21565-82-2)

Isingeniso

I-methyl pent-4-ynoate iyinhlanganisela ye-organic enefomula yamakhemikhali C7H10O2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:

Imvelo:

-Ukubukeka: i-methyl pent-4-ynoate iwuketshezi olungenambala;

-I-Solubility: Incibilika kuzincibilikisi eziphilayo njenge-ethanol ne-ether, okunzima ukuyincibilika emanzini;

-Iphuzu elibilayo: iphuzu layo lokubilisa lingaba ngu-142-144 ℃;

-Ukuminyana: Ukuminyana kwayo kucishe kube ngu-0.95-0.97g/cm³.

Sebenzisa:

-I-Chemical synthesis: i-methyl pent-4-ynoate ivame ukusetshenziswa njengendawo ephakathi ku-organic synthesis futhi ingasetshenziselwa ukuhlanganisa amanye ama-organic compounds;

-Imboni yezinongo namakha: Inephunga elimnandi futhi ingasetshenziswa ekulungiseni izinongo zokudla neziqholo.

Indlela:

I-methyl pent-4-ynoate ingalungiswa ngezindlela ezilandelayo:

-Ukusabela kwe-Etherification: i-pent-1-yne ne-methanol i-esterified phambi kwe-catalyst ukukhiqiza i-methyl pent-4-ynoate.

Ulwazi Lokuphepha:

I-methyl pent-4-ynoate idinga ukunaka ulwazi olulandelayo lokuphepha lapho usebenzisa futhi ugcina:

-ubuthi: i-methyl pent-4-ynoate iyinhlanganisela ephilayo, engase ibe nobuthi obuthile emzimbeni womuntu. Uma usebenzisa, gwema ukuthinta isikhumba namehlo, futhi ugweme ukuhogela umhwamuko wayo;

-umlilo: i-methyl pent-4-ynoate iwuketshezi oluvuthayo, kufanele igweme ukuthintana nelangabi elivulekile nokushisa okuphezulu, isitoreji kufanele sigcinwe kude nomlilo.

Sicela uqaphele ukuthi izinqubo ezifanele zaselabhorethri kanye nezinqubo zokuphepha kufanele zilandelwe lapho kusetshenziswa futhi kusingathwa amakhemikhali, futhi ochwepheshe abafanelekile kufanele kukhulunywe nabo ukuze bathole ulwazi oluningiliziwe lwezokuphepha.
