Steps:

3 Synthesis of diethyl acetal Acrolein
A reaction vessel containing a stirrer, a thermometer and a dropping funnel was charged with 1.36 mol of a 25% sodium sulfite solution, 1.7 mol of a mixture of β-aminopropanal (2), a mass fraction of 55% Of 2-nitrophenol solution (3) 2.3mol, strontium chloride 0 · 56mol, acetonitrile 300ml, control the stirring speed at 180rpm, raise the temperature of the solution to 135 ° C, the reaction 9h, static stratification, remove the oil layer , Washed with sodium bromide solution, the mass fraction of 65% isopropyl alcohol, the mass fraction of 75% triethylamine washing, 1.9kPa vacuum distillation, collecting 90-95 ° C fractions, in the mass fraction of 90% toluene Recrystallization gave 103.43 g of crystalline diethanol acrolein in 83% yield.
