use | for organic synthesis. |
production method | add precooled acrolein dropwise to precooled anhydrous ethanol-hydrogen chloride saturated solution for reaction. The reactants are divided into two layers, separated from the lower acetal, neutralized with powdered sodium bicarbonate, and filtered. The filtrate is washed with ice water, dried, distilled under reduced pressure, and the fraction at 58-62 ℃(1.07kPa) is collected to obtain the product. The yield is 34%. |
