Taw qhia
3-Ethylpyridine yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 3-ethylpyridine:
Zoo:
Cov tsos mob: tsis muaj xim tsis muaj kua.
Ceev: approx. 0.89 g / cm³
Solubility: soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether.
Siv:
Raws li cov kuab tshuaj: nrog nws cov khoom zoo solubility, 3-ethylpyridine feem ntau yog siv los ua cov kuab tshuaj hauv cov organic synthesis thiab ua cov kuab tshuaj thiab reagent hauv cov organic synthesis.
Acid-base indicator: 3-ethylpyridine tuaj yeem siv los ua cov kua qaub-puag qhia thiab ua lub luag haujlwm hauv kev hloov xim hauv acid-base titration.
Txoj kev:
3-Ethylpyridine tuaj yeem tsim los ntawm ethylated pyridine. Ib txoj hauv kev yog los ua pyridine nrog ethylsulfonyl chloride los tsim 3-ethylpyridine.
Cov ntaub ntawv kev nyab xeeb:
Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cuag ntawm daim tawv nqaij thiab qhov muag thaum lub sijhawm ua haujlwm ntawm 3-ethylpyridine, thiab xyuas kom meej tias nws tau ua haujlwm hauv qhov chaw muaj cua zoo kom tsis txhob nqus nws cov vapors.
Yog tias koj ntsib teeb meem nrog 3-ethylpyridine, koj yuav tsum tam sim ntawd yaug nrog dej kom ntau thiab nrhiav kev kho mob sai.
3-Ethylpyridine yuav tsum tau muab cia rau hauv lub thawv airtight, kom deb ntawm qhov kub thiab txias.
