empa-3-yn-2-one (CAS # 1423-60-5) kenyelletso

3-butyne-2-ngoe. Se latelang ke selelekela sa sebopeho sa eona, sepheo, mokhoa oa tlhahiso, le tlhaiso-leseling ea polokeho:

tlhaho:
-Ponahalo: 3-Butyn-2-one ke mokelikeli o se nang 'mala ho isa ho o mosehla o khanyang.
-Monko: E na le monko o monate o tšoanang le oa joala le litholoana.
-Solubility: Ho qhibiliha ka har'a metsoako e mengata ea tlhaho e kang joala le ethers.

Morero:
-3-butyne-2-one e sebelisoa haholo tšimong ea organic synthesis. E ka sebelisoa e le thepa e tala, e thusang, le solvent bakeng sa karabelo ea lik'hemik'hale, 'me e ka nka karolo liketsong tse fapaneng tsa organic synthesis, joalo ka nucleophilic substitution reactions le coupling reactions.

Mokhoa oa tlhahiso:
-Mokhoa o mong oa ho lokisa 3-butyne-2-one ke ka karabelo ea acetone ka joala ba propargyl. Taba ea pele, acetone e arajoa ka sodium hydroxide e feteletseng ho fumana sodium acetate, eo ka nako eo e arabeloang ka joala ba propargyl ka pokellong ea oksijene ho hlahisa 3-butyne-2-one.
-Ho na le mekhoa e meng e fapaneng ea ho hlahisa 3-butyne-2-one, e kang ho arola le ho hloekisa lihlahisoa tsa tlhaho tse amanang le tsona, ho sebelisa mekhoa ea lik'hemik'hale tsa lik'hemik'hale, joalo-joalo.

Lintlha tsa ts'ireletso:
-3-Butyn-2-one e halefisa mahlo, letlalo, le tsamaiso ea ho hema, 'me e lokela ho hlatsuoa hang-hang ka metsi ha e kopana.
- Qoba ho kopana le li-oxidants tse matla, li-acid tse matla, le metheo e matla ho thibela liketso tse kotsi.
-Ha u sebelisa 3-butyne-2-one, li-gloves tse sireletsang lik'hemik'hale, likhalase le mask a sireletsang li lokela ho apesoa ho netefatsa maemo a matle a moea.

Tsena ke matseno a mantlha mabapi le thepa, ts'ebeliso, mekhoa ea ho lokisa, le tlhaiso-leseling ea polokeho ea 3-butyne-2-one. Ha u sebelisa le ho sebetsana le komporo ena, ka kopo etsa bonnete ba hore u latela mekhoa ea ts'ebetso ea ts'ireletso 'me u shebane le tlhaiso-leseling e nepahetseng ea polokeho le Blue Book of Chemical Substances.
