Taw qhia
cis, cis-1,3-cyclooctadiene (cis, cis-1,3-cyclooctadiene) yog cov organic compound nrog cov tshuaj formula C8H12. Nws muaj ob qhov sib txuas ob daim ntawv cog lus thiab muaj yim-ntiv nplhaib qauv.
cis, cis-1,3-cyclooctadiene yog cov kua xim tsis muaj xim nrog cov tshuaj tsw qab tshwj xeeb. Nws tuaj yeem yaj hauv cov kuab tshuaj organic xws li ethanol, tetrahydrofuran thiab dimethylformamide.
hauv chemistry, cis, cis-1,3-cyclooctadiene feem ntau yog siv los ua ligands ntawm kev sib koom ua ke los koom rau hauv kev sib txuas ntawm cov hlau hloov pauv xws li platinum thiab molybdenum. Nws tseem tuaj yeem ua raws li lub hauv paus catalyst nyob rau hauv hydrogenation ntawm unsaturated compounds. Tsis tas li ntawd, cis, cis-1,3-cyclooctadiene kuj tseem siv tau los ua cov khoom nruab nrab ntawm cov dyes thiab cov tshuaj tsw qab.
cis, cis-1,3-cyclooctadiene feem ntau muaj ob txoj kev npaj: ib qho yog los ntawm cov tshuaj tiv thaiv photochemical, uas yog, 1,5-cycloheptadiene raug ultraviolet lub teeb, thiab cis, cis-1,3-cyclooctadiene yog tsim los ntawm cov tshuaj tiv thaiv. Lwm txoj kev yog los ntawm cov hlau catalysis, piv txwv li los ntawm cov tshuaj tiv thaiv nrog cov hlau catalyst xws li palladium, platinum, thiab lwm yam.
Hais txog cov ntaub ntawv kev nyab xeeb ntawm cis, cis-1,3-cyclooctadiene, nws yog cov kua nplaum uas muaj cov yam ntxwv ntawm cov nplaim taws hauv daim ntawv ntawm cov pa lossis roj. Thaum siv thiab khaws cia, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog cov nplaim taws, qhov kub thiab txias thiab oxygen. Tib lub sijhawm, kev sib cuag nrog daim tawv nqaij, qhov muag thiab ua pa ntawm cis, cis-1 thiab 3-cyclooctadiene tuaj yeem ua rau khaus thiab puas. Yog li ntawd, cov hnab looj tes tiv thaiv thiab looj tsom iav yuav tsum hnav thaum siv, thiab yuav tsum tau tswj xyuas qhov chaw ua haujlwm zoo.
