Intshayelelo
I-Ethyl ethynyl carbinol(Ethyl ethynyl carbinol) yi-organic compound kunye ne-chemical formula C6H10O. Ifunyenwe ngokudibanisa iqela le-hydroxyl (iqela le-OH) kwipentyne. Iimpawu zayo zomzimba zezi zilandelayo:
I-Ethyl ethynyl carbinol lulwelo olungenambala nevumba elirhabaxa. Iyanyibilika emanzini kunye nezinyibilikisi ezininzi eziphilayo ezifana ne-alcohol, ii-ethers kunye neester. Inoxinano olusezantsi, ikhaphukhaphu kunamanzi, kwaye inendawo yokubila ephezulu.
I-Ethyl ethynyl carbinol inosetyenziso oluthile kwi-organic synthesis. Ingasetyenziselwa njengento yokuqala kunye nephakathi kwi-organic synthesis, kwaye isetyenziswa rhoqo ekulungiseleleni i-carbonyl-containing compounds. Ingathatha inxaxheba kwi-alkyd esterification, i-olefin Ukongeza, i-saturated hydrocarbon carbonylation reaction. Ukongeza, i-1-pentin-3-ol ingasetyenziselwa ukuhlanganiswa kwedayi kunye neziyobisi.
Indlela yokulungiselela i-Ethyl ethynyl carbinol inokuqhutywa ngamanyathelo alandelayo: okokuqala, i-pentyne kunye ne-sodium hydroxide (NaOH) isabela kwi-ethanol ukuvelisa i-1-pentin-3-ol ityuwa ye-sodium; ke, 1-pentyn-3-ol isodiyam ityuwa iguqulelwa Ethyl ethynyl carbinol ityuwa reaction acidification.
Xa usebenzisa kunye nokuphatha i-Ethyl ethynyl carbinol, kufuneka unikele ingqalelo kule ngcaciso yokhuseleko ilandelayo: Iyacaphukisa kwaye inokubangela ukucaphuka kunye nokwenzakala kwesikhumba kunye namehlo, ngoko kufuneka unxibe izixhobo ezifanelekileyo zokukhusela zomntu, ezifana neeglavu kunye nezibuko. Ukongezelela, iyatsha kwaye kufuneka igwenywe ekudibaneni nomlilo ovulekileyo okanye imithombo yokushisa ephezulu, kwaye igcinwe ngokufanelekileyo. Nakuphi na ukuphatha okunye okanye ukugcinwa okuhambelana nekhompawundi kufuneka kuqhutywe ngokuhambelana neenkqubo zokusebenza ezikhuselekileyo.
