Taw qhia
Benzyl cawv 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 benzyl cawv:
Zoo:
- Cov tsos mob: Benzyl cawv yog xim tsis muaj xim rau cov kua daj daj.
- Solubility: Nws yog me ntsis soluble hauv dej thiab soluble ntau dua hauv cov kuab tshuaj organic xws li ethanol thiab ethers.
- txheeb ze molecular hnyav: tus txheeb ze molecular hnyav ntawm benzyl cawv yog 122.16.
- Flammability: Benzyl cawv yog flammable thiab yuav tsum tau ceev kom deb ntawm qhov qhib nplaim taws thiab kub kub.
Siv:
- Cov kuab tshuaj: Vim nws zoo solubility, benzyl cawv feem ntau yog siv los ua cov organic hnyav, tshwj xeeb tshaj yog nyob rau hauv cov xim thiab coatings kev lag luam.
Txoj kev:
- Benzyl cawv tuaj yeem npaj tau los ntawm ob txoj hauv kev:
1. Los ntawm alcohololysis: Benzyl cawv tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm sodium benzyl cawv nrog dej.
2. Benzaldehyde hydrogenation: benzaldehyde yog hydrogenated thiab txo kom tau benzyl cawv.
Cov ntaub ntawv kev nyab xeeb:
- Benzyl cawv yog cov organic, thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog lub qhov muag, tawv nqaij, thiab noj.
- Thaum muaj kev sib cuag tsis raug, tam sim ntawd yaug qhov chaw cuam tshuam nrog dej txaus thiab nrhiav kev kho mob.
- Kev nqus tau ntawm benzyl cawv vapor tuaj yeem ua rau kiv taub hau, ua pa nyuaj thiab lwm yam kev cuam tshuam, yog li yuav tsum muaj chaw ua haujlwm zoo.
- Benzyl cawv yog cov khoom siv hluav taws xob thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua, kom deb ntawm cov nplaim taws thiab qhov kub thiab txias.
- Thaum siv benzyl cawv, ua raws li cov txheej txheem kev nyab xeeb thiab kev tiv thaiv tus kheej.
