Taw qhia

Myrcene yog cov kua uas tsis muaj xim rau yellowish nrog ib qho tshwj xeeb aroma uas feem ntau pom nyob rau hauv nplooj thiab txiv hmab txiv ntoo ntawm laurel ntoo. Cov hauv qab no yog kev qhia txog qee yam ntawm cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm myrcene:

 

Zoo:

- Nws muaj qhov tshwj xeeb ntuj aroma zoo ib yam li cov nplooj laurel.

- Myrcene yog soluble hauv ntau cov kuab tshuaj organic xws li cawv, ethers, thiab hydrocarbon solvents.

 

Siv:

 

Txoj kev:

- Cov kev npaj tseem ceeb muaj xws li distillation, extraction thiab tshuaj synthesis.

- Distillation extraction yog rho tawm ntawm myrcene los ntawm distilling dej vapor, uas muaj peev xwm rho tawm cov compound ntawm nplooj los yog txiv hmab txiv ntoo ntawm laurel ntoo.

- Txoj cai lij choj ntawm cov tshuaj synthesis yog kev npaj ntawm myrcene los ntawm kev sib txuas thiab hloov lwm cov organic sib txuas, xws li acrylic acid lossis acetone.

 

Cov ntaub ntawv kev nyab xeeb:

- Myrcene yog ib yam khoom ntuj tsim thiab feem ntau suav hais tias muaj kev nyab xeeb, tab sis kev raug ntau dhau tuaj yeem ua rau tawv nqaij rhiab heev lossis khaus khaus.

- Kev saib xyuas yuav tsum tau ua kom tsis txhob raug ncua ntev ntawm cov tshuaj myrcene siab thiab tsis txhob nqus los yog noj thaum siv myrcene.

- Ua raws li cov lus qhia ntawm cov khoom lag luam thiab cov txheej txheem ua haujlwm nyab xeeb thiab ua raws li kev ceev faj tsim nyog xws li hnab looj tes thiab cov cuab yeej tiv thaiv ua pa thaum siv myrcene.
