-
1-(4-aminophenyl)-2-(1-piperidino)-1-propanone hydrochloride,a sort of water-soluble photoinitiator,was synthesized from acetanilide in three steps,i.e.Friedel-Crafts acylation,α-bromination,amination and hydrochlorination,and its structure was analyzed by IR,MS,UV,elemental analysis,1H NMR.During the 3rd step,water acted as solvent and piperidine was dripped in at ambient temperature.After reaction at 40℃ for 2 h,the mixture was treated with 15%(volume fraction) HCl.The yield was 60.7%.The product has good solubility and photoinitiability.In the air with the distance of 20 cm,the curing time of photosensitive prepolymer was 10s only.
