Taw qhia
Heptanal. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm heptanaldehyde:
Zoo:
1. Cov tsos mob: Heptanal yog cov kua tsis muaj xim nrog cov ntxhiab tsw tshwj xeeb.
2. Ceev: Heptanal muaj qhov ceev dua, txog 0.82 g / cm³.
4. Solubility: Heptanal yog soluble hauv cawv thiab ether solvents, tab sis yuav luag insoluble hauv dej.
Siv:
1. Heptanaldehyde yog ib qho tseem ceeb nyob rau hauv nruab nrab compound, uas yuav siv tau nyob rau hauv zus tau tej cov biodiesel, ketones, acids thiab lwm yam tebchaw.
2. Heptanaldehyde feem ntau siv rau hauv kev tsim cov tshuaj tsw qab hluavtaws, resins, yas, thiab lwm yam.
3. Heptanaldehyde kuj tseem siv tau los ua cov tshuaj reagent thiab tuaj yeem siv rau hauv cov organic synthesis, surfactant thiab lwm yam.
Txoj kev:
Muaj ob txoj hauv kev tseem ceeb rau kev npaj ntawm heptanaldehyde:
1. Heptane oxidation: Heptanaldehyde tuaj yeem npaj los ntawm oxidation cov tshuaj tiv thaiv ntawm heptane thiab oxygen ntawm qhov kub thiab txias.
2. Etherification ntawm vinyl cawv: Heptanal kuj tau los ntawm etherification ntawm 1,6-hexadiene nrog vinyl cawv.
Cov ntaub ntawv kev nyab xeeb:
1. Heptanaldehyde muaj ntxhiab tsw thiab muaj qhov ua rau khaus ntawm lub qhov muag thiab ua pa, yog li nws yuav tsum tau ceev kom deb ntawm qhov muag, qhov ncauj thiab qhov ntswg.
2. Heptanaldehyde yog khaus rau ntawm daim tawv nqaij, yog li nws yuav tsum tau yaug nrog dej tam sim ntawd tom qab kev sib cuag.
3. Heptanaldehyde vapor tuaj yeem ua rau mob taub hau, kiv taub hau thiab lwm yam tsos mob tsis xis nyob, thiab yuav tsum tau siv rau hauv qhov chaw muaj cua zoo.
4. Heptanaldehyde yog cov kua hluav taws xob, yog li tsis txhob sib cuag nrog cov nplaim taws qhib thiab kub kub.
