2,3-di(prop-2-enoyloxy)propyl prop-2-enoate

Conditions: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Propoxylated glycerol triacrylate (GPTA—OTA 480, 5.08 g) was added to N-methylaniline (6.42 g—an equivalent amount required to react with the three acrylate groups, had the reactant been glycerol triacrylate) in glacial acetic acid (10 ml). The reaction mixture was heated at 100° C. for 2 hours and then the acetic acid removed by vacuum distillation. A portion of the residue (11 g) was then subjected to steam distillation to remove the excess N-methylaniline and the product extracted with dichloromethane (25 ml). The extract was dried over anhydrous magnesium sulphate, filtered and the dichloromethane removed by distillation in vacuo to leave a pale brown-coloured oil (6.46 g). to react with the three acrylate groups the acetic acid removed by vacuum distillation A portion of the residue (11 g) was then subjected to steam distillation to remove the excess N-methylaniline the product extracted with dichloromethane (25 ml) The extract was dried over anhydrous magnesium sulphate filtered the dichloromethane removed by distillation in vacuo
