Thepa: Ke mokelikeli o se nang 'mala o nang le monko o khethehileng o hlabang.

- 2-Butyn-1-ol e qhibiliha ka metsing le metsoako e mengata ea tlhaho e kang ethanol le ether.

- Ke motsoako oa joala o nang le lihlopha tse sebetsang tsa alkyne tse nang le lik'hemik'hale tse ling tsa joala le alkynes.

 

Sebelisa:

- 2-butyn-1-ol e sebelisoa haholo ho organic synthesis joalo ka karabelo ea lipakeng kapa reagent. E ka sebelisoa e le sesebelisoa sa ho qala, solvent, kapa catalyst bakeng sa motsoako oa metsoako ea manyolo.

- E ka boela ea sebelisoa ho lokiseng metsoako e meng e tšoanang e kang ethers, ketones, le etherketones.

 

Mokhoa:

- 2-Butyno-1-ol e ka lokisoa ke karabelo ea joala ea hydrogenated acetone le chloroform.

- Mokhoa o mong o tloaelehileng oa ho itokisa ke ho kopanya ethyl mercaptan le acetone ka pel'a amino catalyst, ebe o fumana 2-butyn-1-ol ka ho eketsa mercury chloride.
