Participants

Reaction Steps

A solution of 120 g. of acrylamide and 114 g. of 3-diallylaminoallylidenemalononitrile (A) in 500 cc. of ethanol was refluxed. 3.2 g. of AZBN were added and the solution was refluxed for one hour under stirring. A solution of 104 g. of acrylamide, 800 cc. of ethanol and 3.2 g. of AZBN was added and the solution was refluxed for one hour under stirring. A solution of 88 g. of acrylamide, 400 cc. of ethanol and 2.4 g. of AZBN was added and refluxed for one hour. A solution of 72 g. of acrylamide, 400 cc. of ethanol and 1.6 g. of AZBN was added and the solution was refluxed for one hour. In conclusion a solution of 56 g. of acrylamide, 400 cc. of ethanol and 1.6 g. of AZBN was added and refluxed for 2 hours. The mixture was cooled, filtered, washed with ethanol and then with ethyl ether and vacuum dried at 50° C. 478 g. of a product containing about 9% aminoallylidenemalononitrile units in weight were obtained, the product solution at 6% in water diluted 1:2000 with water had an optical density of 0.76 at 382 nm.
