実験手順

To a solution of 40 parts of o-t-butylphenol, 75 parts of epichlorhydrin, and 40 parts of ethanol boiling under reflux with stirring was added dropwise over 10 minutes a solution of 17.6 parts of potassium hydroxide dissolved in 66 parts of ethanol and the minimum amount of water. The mixture was stirred and refluxed for 105 minutes, cooled, diluted with water, and well extracted with ether, which was then washed with water, dried over magnesium sulphate, and evaporated to an oil. Distillation at 144°/8 mm afforded 43 parts of 3-(2-t-butylphenoxy)-1,2-epoxypropane as a clear oil.
