Taw qhia

2,6-Dimethoxyphenol, tseem hu ua p-methoxy-m-cresol, 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 2,6-dimethoxyphenol:

 

Khoom: Nws yog dawb crystalline khoom nrog ib tug aromatic aromatic saj. Nws yuav luag insoluble hauv dej ntawm chav tsev kub tab sis soluble hauv cov kuab tshuaj organic xws li ethanol thiab methylene chloride.

 

Siv:

 

Txoj kev:

Txoj kev npaj ntawm 2,6-dimethoxyphenol tuaj yeem ua tiav los ntawm methyl etherification ntawm p-cresol. Tshwj xeeb, p-cresol tuaj yeem cuam tshuam nrog methanol thiab rhuab thiab refluxed siv cov kua qaub catalyst (xws li sulfuric acid) los tsim 2,6-dimethoxyphenol.

 

Cov ntaub ntawv kev nyab xeeb:

Kev raug rau 2,6-dimethoxyphenol yuav tsum raug zam kom ntau li ntau tau. Tej zaum nws yuav muaj kev cuam tshuam rau qhov muag, tawv nqaij, thiab ua pa. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes thiab tsom iav yuav tsum hnav thaum siv lossis tuav.
