Taw qhia
Methylbenzaldehyde. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm methylbenzaldehyde:
Zoo:
- Cov tsos mob: Methylbenzaldehyde yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw muaj zog.
- Solubility: Nws yog soluble hauv ntau cov kuab tshuaj organic xws li cawv thiab ethers.
- Cov tshuaj tiv thaiv tshuaj: Methylbenzaldehyde yog ib hom aldehyde uas muaj cov tshuaj tiv thaiv aldehyde, xws li reacting nrog mercaptan los tsim mercaptan formaldehyde.
Siv:
- Fragrances: Methylbenzaldehyde, raws li ib qho ntawm cov khoom xyaw ntawm perfumes thiab fragrances, muaj cov yam ntxwv aromatic thiab haum rau cov khoom xws li perfumes, flavors, soaps, thiab lwm yam.
Txoj kev:
Methylbenzaldehyde tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm benzaldehyde nrog methanol:
C6H5CHO + H3OH → CH3C6H4CHO + H2O
Cov ntaub ntawv kev nyab xeeb:
- Methylbenzaldehyde yog tshuaj lom rau tib neeg thiab tuaj yeem ua rau khaus tawv nqaij, qhov muag, thiab ua pa. Yuav tsum tau ceev faj kom tsim nyog thaum tuav, xws li hnav hnab looj tes, qhov ncauj qhov ntswg, thiab tsom iav.
- Nws yog cov kua dej uas muaj hluav taws kub thiab yuav tsum tau muab cia rau hauv lub thawv airtight, kom deb ntawm qhov hluav taws kub thiab cua sov.
- Ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam thaum siv thiab khaws cia, thiab xyuas kom cov khoom siv thiab ntsuas los teb cov xwm txheej kub ntxhov.
- Hauv kev pov tseg pov tseg, nws yuav tsum tau kho kom zoo thiab pov tseg raws li cov cai hauv zos kom tsis txhob muaj kuab paug rau ib puag ncig.
