5-CYANO-1-PENTYNE (CAS# 14918-21-9)
imvelo
I-acetylene nitrile iye yakhiqizwa. Iwuketshezi olungenambala olunephunga elimnandi. Okulandelayo ezinye zezakhiwo eziyinhloko ze-acetylenic nitriles:
1. Ukunyibilika: I-Nitrile inokuncibilika okuphansi emanzini, kodwa ingancibilika kwezinye izincibilikisi eziphilayo ezifana notshwala, ama-ether, ama-ketone, ama-hydrocarbon ane-chlorine, njll.
2. Ukuzinza: I-Nitrile izinzile uma kuqhathaniswa nezinga lokushisa legumbi, kodwa ithola ukusabela kwe-polymerization lapho ishiswa. Ingasabela ngezinto ezinamaqembu asebenzayo, njengama-alcohols, ama-acids, njll., ukwenza izinhlanganisela ezahlukene.
3. Ubuthi: I-Nitrile inobuthi obuthile futhi ingacasula isikhumba nolwelwesi lwamafinyila. Ukuchayeka isikhathi eside noma ukudla ngokweqile kwe-acetylenic nitriles kungadala izingozi ezithile zempilo.
4. Ukusabela kwamakhemikhali: I-acetylene nitrile ingabhekana nokusabela kokwengezwa, ukusabela kwe-hydrogenation, ukusabela kokwengezwa kwama-electron, njll. Okuvame ukusetshenziselwa ukuhlanganiswa okubalulekile kwezinto eziphilayo njengama-ketone, ama-ester, njll.
imininingwane yezokuphepha
I-Nitrile (eyaziwa nangokuthi i-acetylene wax) iyikhemikhali. Okulandelayo ulwazi lokuphepha mayelana ne-acetylene nitrile:
1. Ubuthi: I-Nitrile iyikhemikhali enobuthi engangena emzimbeni womuntu ngokuhogela, ukuthinta isikhumba, nangokuyidla. Iyacasula futhi idle, futhi ingase ibangele ukulimala esikhumbeni, emehlweni, ohlelweni lokuphefumula, kanye nesistimu yokugaya ukudla.
2. Ukuthintana kwesikhumba: I-Nitrile ingabangela ukucasuka kwesikhumba kanye nokungezwani komzimba.
3. Ukuthintana kwamehlo: Ukuchayeka ku-acetylene kungase kubangele ukucasuka okukhulu kwamehlo nokulimala. Uma kwenzeka ukuthintana, geza ngokushesha amehlo ngamanzi amaningi okungenani imizuzu eyi-15 futhi ufune usizo lwezokwelapha ngokushesha.
4. Imiphumela yesistimu yokuphefumula: Ukuhogela umhwamuko we-acetylene kungase kubangele ukucasuka kokuphefumula, umphimbo obuhlungu, ukukhwehlela, ukuphefumula kanzima, nokuqina kwesifuba.
5. Izinyathelo zosizo lokuqala: Uma kwenzeka uhogela umoya, uthinta isikhumba, noma uthintana neso nge-acetylene nitrile, kufanele kuthathwe izinyathelo zosizo lokuqala ngokushesha futhi kufuneke ukunakekelwa kwezokwelapha ngokushesha.
6. Ukugcina Nokuphatha: I-Nitrile kufanele igcinwe endaweni emnyama, evalekile, futhi engenawo umoya. Kufanele igcinwe ngokuhlukana nama-oxidants nama-acids aqinile. Lapho uphatha i-acetylene nitrile, izinto zokuzivikela ezinjengamagilavu, izibuko, nezingubo zokuzivikela kufanele zigqokwe.
