5-CYANO-1-PENTYNE (CAS# 14918-21-9)
indalo
I-acetylene nitrile iye yaveliswa. Lulwelo olungenambala nevumba elinukayo. Ezi zilandelayo zezinye zeempawu eziphambili ze-acetylenic nitriles:
1. Ukunyibilika: I-Nitrile ine-solubility ephantsi emanzini, kodwa inokunyibilika kwezinye izinyibilikisi ze-organic ezifana ne-alcohol, i-ethers, i-ketones, i-hydrocarbons e-chlorinated, njl.
2. Uzinzo: I-Nitrile izinzile kwiqondo lobushushu begumbi, kodwa ifumana i-polymerization reaction xa ishushu. Iyakwazi ukusabela ngezinto ezinamaqela asebenzayo, afana ne-alcohols, i-acids, njl., ukwenza iikhompawundi ezahlukeneyo.
3. Ubutyhefu: I-Nitrile inetyhefu ethile kwaye inokucaphukisa ulusu kunye ne-mucous membranes. Ukuvezwa kwexesha elide okanye ukuthathwa ngokugqithisileyo kwe-acetylenic nitriles kunokubangela iingozi ezithile zempilo.
4. Iimpendulo zeMichiza: I-acetylene nitrile inokungena kwiimpendulo zokongezwa, i-hydrogenation reactions, i-electron add reactions, njl. Ngokuqhelekileyo isetyenziselwa ukudibanisa i-organic compounds ebalulekileyo njenge-ketones, i-esters, njl.
ulwazi lokhuseleko
I-Nitrile (ekwabizwa ngokuba yi-acetylene wax) yikhemikhali. Oku kulandelayo lulwazi lokhuseleko malunga ne-acetylene nitrile:
1. Ubutyhefu: I-Nitrile yikhemikhali eyityhefu enokungena emzimbeni womntu ngokuphefumla, ukudibana nolusu, kunye nokungeniswa. Iyacaphukisa kwaye iyatshisa, kwaye inokubangela umonakalo esikhumbeni, emehlweni, kwisixokelelwano sokuphefumla, kunye nenkqubo yokwetyisa.
2. Uqhagamshelwano lwesikhumba: I-Nitrile inokubangela ukucaphuka kwesikhumba kunye nokuchasana nomzimba.
3. Ukudibana kwamehlo: Ukuvezwa kwi-acetylene kunokubangela ukucaphuka kwamehlo kunye nomonakalo. Ukuba unxibelelwano luyenzeka, hlambulula ngokukhawuleza amehlo ngamanzi amaninzi ubuncinane imizuzu eyi-15 kwaye ufune unyango ngokukhawuleza.
4. Iziphumo zenkqubo yokuphefumla: Ukuphefumla umphunga we-acetylene kunokubangela ukucaphuka kokuphefumla, umqala obuhlungu, ukukhohlela, ukuphefumla nzima, kunye nokuqina kwesifuba.
5. Amanyathelo oncedo lokuqala: Xa kwenzeka ukuphefumla, ukudibana kwesikhumba, okanye ukudibana kwamehlo ne-acetylene nitrile, amanyathelo oncedo lokuqala kufuneka athathwe ngokukhawuleza kwaye unyango kufuneka lufunwe ngokukhawuleza.
6 Ukugcinwa Nokuyiphatha: I-Nitrile ifanele igcinwe kwindawo emnyama, evaliweyo nengenamoya. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants kunye ne-acids eqinile. Xa uphethe i-acetylene nitrile, izixhobo zokuzikhusela ezifana neeglavu, iiglasi, kunye nempahla yokukhusela kufuneka zinxitywe.
