Taw qhia

Alkynycyclohexanol yog ib qho organic compound.

 

Cov khoom ntawm alkynyl cyclohexanol:

- Cov kua dej tsis muaj xim zoo nkauj, soluble hauv dej thiab cov organic solvents.

- Muaj cov ntxhiab tsw ntxhiab tsw ntawm chav tsev kub.

- Alkyne cyclohexanol muaj qhov ua haujlwm siab thiab tuaj yeem ua tiav ntau yam tshuaj lom neeg, xws li cov tshuaj tiv thaiv ntxiv thiab cov tshuaj tiv thaiv oxidation.

 

Kev siv alkynycyclohexanol:

- Ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis, nws yog siv los tsim ntau yam organic tebchaw, xws li aldehydes, ketones, cawv thiab esters.

 

Txoj kev npaj ntawm alkyne cyclohexanol:

Muaj ntau ntau txoj hauv kev los npaj alkynyl cyclohexanol, thiab cov khoom siv feem ntau suav nrog:

- Isobutylene yog siv los ua raw khoom, hydrogenated nyob rau hauv acidic tej yam kev mob los tsim isobutenol, thiab ces los ntawm alkali catalysis, ib tug rearrangement cov tshuaj tiv thaiv tshwm sim kom tau alkyne cyclohexanol.

- Hydrogen pressurized cov tshuaj tiv thaiv: cyclohexene thiab hydrogen react nyob rau hauv lub xub ntiag ntawm ib tug catalyst tsim alkyne cyclohexanol.

 

Cov ntaub ntawv kev nyab xeeb rau alkynocyclohexanol:

- Cyclhexanol ua rau khaus thiab tuaj yeem ua rau khaus thiab liab thaum nws los rau ntawm daim tawv nqaij thiab qhov muag.

- Tej zaum yuav ua rau muaj kev fab tshuaj, tiv thaiv tus kheej thaum siv nws.

- Thaum lub sijhawm ua haujlwm, kev nqus pa ntawm nws cov vapors thiab plua plav yuav tsum zam kom tsis txhob ua rau lub ntsws ua pa.

- Thaum khaws cia, yuav tsum tau muab kaw kom nruj, nyob rau hauv qhov chaw txias, qhuav, deb ntawm hluav taws kub thiab kub.
