Taw qhia

Nerolidol, lub npe tshawb fawb 1,3,7-trimethylhexylbenzene (4-O-methyl) hexanone, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm nerolidol:

 

Zoo:

Nerolidol yog ib yam khoom uas muaj dawb crystalline hmoov nyob rau hauv tsos. Nws muaj lub aroma ntawm txiv kab ntxwv thiab kuj tau txais nws lub npe. Nws muaj qhov sib txheeb molecular hnyav li ntawm 262.35 g / mol thiab qhov ceev ntawm 1.008 g / cm³. Nerolil yuav luag insoluble hauv dej ntawm chav tsev kub, tab sis nws tuaj yeem soluble hauv cov kuab tshuaj organic xws li cawv thiab ethers.

 

Siv: Nws lub cim txiv kab ntxwv aroma ua rau nws yog ib qho ntawm cov khoom tseem ceeb hauv ntau yam khoom.

 

Txoj kev:

Nerolidol feem ntau yog npaj los ntawm cov txheej txheem tshuaj hluavtaws. Ib txoj kev npaj siv feem ntau yog los ua ke nerolidol los ntawm reacting hexanone thiab methanol nrog hydrochloric acid ua catalyst. Txoj kev npaj tshwj xeeb yuav tsum tau ua nyob rau hauv ib lub chaw kuaj tshuaj los yog tshuaj chemical plant.
