Abstract
The solution concerns a method of preparation of technical N-butoxymethylacryamide or N-isobutoxymethylacrylamide from solution of relative N-hydroxymethyl derivatives in corresponding alcohol by etherification by the same alcohol. The molar surplus of the alcohol to the initial amide is selected within range of 1 to 2 moles, where a part of the alcohol (0.2 to 1.0 mol) is added to the reactor in the course of etherification at simultaneous removal of azeotropic mixture of alcohol-water. The speed of the removal of the azeotrope and the temperature of the reaction mixture are controlled by gradual reduction of pressure in the reactor so that the temperature of the content of the rector would not exceed 90 degrees C and the temperature of the heating medium would not exceed 115 degrees C. After refining of the obtained crude etherificate by washing and subsequent vacuum distillation of separated organic phase we obtain final product containing more than 85 percent by weight of the main component. The yield of the whole process ranges after recalculation per 100 percent of the product between 80 to 85 percent theory per acryl amide and 75 to 82 percent per formaldehyde introduced in the first reaction stage, which is the production of solutions of N-hydroxyalkyl derivatives in the selected alcohol
