반응 단계
126 g of α-ethylacrolein, 300 g of a 30% strength aqueous solution of formaldehyde, 1 g of hydroquinone and 350 g of 1,4-dioxane were combined at 25° C to give a solution. After about 2 hours, 120 g of this solution, which had a pH value of 2-3, were hydrogenated as in Example 1. Analysis of the hydrogenated product gave 55.9% of 2-ethyl-2-methylpropane-1,3-diol and 34% of methylbutanol, relative to the α-ethylacrolein employed.
