Taw qhia
1-octyne-3-ol (1-octyne-3-ol) yog cov organic compound. Hauv qab no yog cov lus piav qhia ntxaws txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
1-Octynyl-3-ol yog cov kua tsis muaj xim uas muaj ntxhiab tsw. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, chloroform, thiab dimethylformamide.
Siv:
1-Octyn-3-ol muaj ntau yam kev siv hauv cov organic synthesis. Nws tseem tuaj yeem siv los npaj cov khoom siv hluav taws xob zoo-sensitized solar cells nrog rau cov catalysts rau lwm cov organic synthesis cov tshuaj tiv thaiv.
Txoj kev:
1-Octyn-3-ol tuaj yeem ua ke los ntawm ntau txoj hauv kev. Ib txoj hauv kev yog los ua 1-bromooctane nrog acetylene los tsim 1-octyne-3-bromo. Tom qab ntawd, los ntawm kev ua ntawm sodium hydroxide, 1-octyno-3-bromide hloov mus rau 1-octyno-3-ol.
Cov ntaub ntawv kev nyab xeeb:
1-Octynyl-3-ol yog ib qho ua rau khaus khaus thiab yuav tsum tau ua nrog hnab looj tes thiab tsom iav kom tsis txhob sib cuag nrog daim tawv nqaij lossis qhov muag. Cov vapor kuj ua rau cov kab mob ua pa thiab yuav tsum tau ua kom cua zoo thaum ua haujlwm. Nws kuj yog combustible thiab yuav tsum tsis txhob los rau hauv kev sib cuag nrog hluav taws. Thaum siv los yog khaws cia, muab tso rau hauv ib lub thawv airtight thiab kom deb ntawm tshav kub thiab nplaim taws.
