Taw qhia
Trans-2,4-heptadienal yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
Trans-2,4-heptadienal yog cov xim tsis muaj xim rau lub teeb daj nrog cov ntxhiab tsw. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether thiab insoluble hauv dej.
Kev Siv: Nws kuj tseem siv tau los ua cov kuab tshuaj thiab nruab nrab hauv cov chaw kuaj tshuaj.
Txoj kev:
Trans-2,4-heptadienal feem ntau yog npaj los ntawm oxidation ntawm heptenic acid. Heptenic acid yog thawj zaug oxidized rau heptadienoic acid, thiab tom qab ntawd nkag mus rau decarboxylation cov tshuaj tiv thaiv kom tau txais trans-trans-2,4-heptadienal.
Cov ntaub ntawv kev nyab xeeb:
Trans-2,4-heptadienal yog cov kua ua kua thiab yuav tsum tau ceev kom deb ntawm hluav taws thiab kub kub. Yuav tsum tau ntsuas kev nyab xeeb, xws li hnav looj tsom iav, hnab looj tes thiab khaub ncaws tiv thaiv, yuav tsum tau ua thaum ua haujlwm. Tsis txhob nqus nws cov vapors thiab xyuas kom meej tias qhov chaw ua haujlwm yog qhov cua zoo. Yog tias nws nkag mus rau ntawm daim tawv nqaij, yaug tam sim ntawd nrog dej ntau thiab nrhiav kev kho mob. Yog tias nqos tau, mus ntsib kws kho mob tam sim ntawd.
