Taw qhia

()-rose oxide, los yog anisole (C6H5OCH3), yog cov organic compound. Cov hauv qab no yog kev qhia txog qee yam khoom, kev siv, txoj kev thiab cov ntaub ntawv kev nyab xeeb txog ()-rose oxide:

 

Xwm:

-Qhov tsos:()-rose oxide yog cov kua tsis muaj xim thiab pob tshab nrog cov tshuaj tsw qab zoo li sawv.

- solubility:()-rose oxide tuaj yeem yaj hauv dej thiab feem ntau cov kuab tshuaj organic, tab sis insoluble hauv aliphatic hydrocarbons.

-Boiling point: ( ) - Lub boiling point ntawm Rose oxide yog hais txog 155 ℃.

- ntom:() - qhov ntom ntawm Rose oxide yog li 0.987 g / cm³.

 

Siv:

-spices: Vim nws cov ntxhiab tsw tshwj xeeb, ( )-rose oxide feem ntau yog siv los ua cov khoom xyaw thiab siv dav hauv cov tshuaj pleev ib ce, naj hoom thiab lwm yam khoom.

-Qhov hnyav:()-rose oxide tuaj yeem siv los ua cov kuab tshuaj organic kom yaj thiab dilute ntau yam tshuaj hauv qee qhov kev lag luam thiab cov chaw sim.

-Chemical synthesis: ( ) -rose oxide kuj siv tau los ua ib qho substrate lossis cov tshuaj tiv thaiv nruab nrab hauv cov organic synthesis.

 

Txoj Kev Npaj:

() - Rose oxide tuaj yeem npaj tau los ntawm kev ua haujlwm benzyl cawv nrog sulfuric acid:

C6H5OH CH3OH → C6H5OCH3 H2SO4

 

Cov ntaub ntawv kev nyab xeeb:

- ( ) - Rose oxide tuaj yeem ua rau hluav taws kub nyhiab los ntawm Flash Point (flash point yog 53 ℃) ntawm qhov kub thiab txias, yog li kev sib cuag nrog nplaim taws thiab lwm qhov hluav taws kub yuav tsum raug zam.

-Vapors ntawm cov khoom tuaj yeem ua rau lub qhov muag, ua pa thiab tawv nqaij. Thaum siv, qhov cua zoo yuav tsum tau ua kom ntseeg tau.

-( ) - Rose oxide yuav tsum tsis txhob muab pov tseg rau hauv cov kua dej los yog mus rau hauv cov av ntau kom tsis txhob muaj kuab paug rau ib puag ncig.

-Thaum siv thiab khaws cia, khaws cia kom deb ntawm oxidants, qhov hluav taws kub thiab qhov chaw kub.
