Taw qhia
(E)-2-heptenal yog cov organic compound. Cov hauv qab no yog cov lus qhia luv luv rau cov khoom, kev siv, kev npaj, thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw:
Zoo:
(E)-2-heptenal yog cov kua tsis muaj xim uas muaj ntxhiab tsw. Cov tshuaj muaj zog polarity thiab soluble nyob rau hauv ethanol thiab ether solvents.
Siv:
(E)-2-heptenal muaj qee yam kev siv nyiaj hauv kev lag luam tshuaj. Nws yog tsuas yog siv los ua ib qho nruab nrab hauv kev sib txuas ntawm cov tshuaj tsw qab thiab lwm cov tebchaw.
Txoj kev:
Kev npaj ntawm (E)-2-heptenal feem ntau yog tau los ntawm oxidation ntawm heptene. Ib txoj hauv kev yog kom dhau cov pa oxygen mus rau hauv kev daws ntawm heptene's acetic acid acyl oxidizer los tsim (E)-2-heptenal thiab acetic acid. Cov txheej txheem kho tom qab muaj xws li distillation, purification, thiab tshem tawm cov impurities.
Cov ntaub ntawv kev nyab xeeb:
(E)-2-heptenal yog ib qho ua rau khaus khaus thiab yuav tsum tau saib xyuas rau nws qhov kev sib cuag thiab nqus pa. Lub sij hawm ntev los yog qhov tseem ceeb yuav ua rau muaj kev cuam tshuam rau ntawm daim tawv nqaij, qhov muag, thiab ua pa. Thaum siv (E)-2-heptenal, kev ceev faj tsim nyog xws li hnab looj tes tiv thaiv thiab tsom iav yuav tsum tau ua kom muaj cua zoo. Thaum khaws cia thiab tuav cov khoom sib xyaw no, yuav tsum tau ua raws li cov kev coj ua muaj kev nyab xeeb, thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog cov khoom siv hluav taws xob thaum muaj hluav taws kub lossis tawg.
