说明

一般描述

1,4-Dioxane is widely used as a solvent for various organic compounds in industry. It is a non-biodegradable contaminant found in industrial effluents. Oxidative degradation of 1,4-dioxane by using oxygen and ozone has been useful in converting it into biodegradable products, which can be easily removed by conventional methods.[1]
 

应用

1,4-Dioxane has been employed as a solvent in the synthesis of N-(4-(prop-2-ynyloxy)phenyl)acetamide and 3-(4-(prop-2-ynyloxy)phenyl)-3,4-dihydro-2H-benzo[e][1,3]oxazine.[2]
