Reaction Steps

55.4 g (0.2 mol) of ethyl 2-cyano-3,3-diphenylacrylate (Uvinul 3035), 100 ml of 3,3,5-trimethylcyclohexanol and 4 g of Na2CO3 were reacted with one another at 181-184° C. with distillative removal of the ethanol formed, assisted by a stream of nitrogen. After about 5 h, the reaction mixture was filtered hot in order to remove the Na2CO3. After the filtrate had been cooled, the precipitate which had formed was filtered off, washed with cyclohexane and dried, giving 29 g (39%) of 3,3,5-trimethylcyclohexyl 2-cyano-3,3-diphenylacrylate [λmax=301 nm, E11=344] as a colorless solid.
