Taw qhia

4-Pentyny-1-ol, tseem hu ua hexynyl cawv. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 4-pentynyn-1-ol:

 

Zoo:

4-Pentoyn-1-ol yog cov kua uas tsis muaj xim rau daj daj nrog cov ntxhiab tsw. Nws yog ib qho tsis ruaj khov uas zoo li polymerize los yog ua rau nws tus kheej.

 

Siv:

4-Pentyne-1-ol muaj cov khoom ntawm alkyne thiab tuaj yeem siv rau hauv kev sib txuas ntawm lwm cov organic tebchaw. Nws feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis thiab tuaj yeem siv los npaj ethers, esters, aldehydes thiab lwm cov tebchaw.

 

Txoj kev:

Muaj ntau txoj hauv kev los npaj 4-pentyn-1-ol. Ib txoj hauv kev yog los ua 1,2-dibromoethane nrog sodium ethanol los tsim pentynylethanol, thiab tom qab ntawd npaj 4-pentyn-1-ol los ntawm cov tshuaj tiv thaiv hydrogenation.

 

Cov ntaub ntawv kev nyab xeeb:

4-Pentoyn-1-ol tsis ruaj khov thiab ua rau nws tus kheej tshwm sim, thiab yuav tsum tau ua tib zoo saib xyuas thaum tuav. Nws yog flammable thiab yooj yim rau explosive sib tov thaum raug qhib nplaim taws los yog kub kub. Kev sib cuag nrog daim tawv nqaij lossis qhov muag yuav ua rau mob thiab khaus khaus, thiab kev tiv thaiv tus kheej xws li hnab looj tes thiab tsom iav yuav tsum tau noj thaum ua li ntawd. Ua haujlwm nyob rau hauv qhov chaw uas muaj cua zoo thiab nyob deb ntawm hluav taws. Yog nqus tau los yog nqus tau, nrhiav kev kho mob tam sim ntawd. Thov ua raws li cov txheej txheem kev nyab xeeb rau kev siv kom raug.
