Abstract:A new method was developed for the preparation of procaine by catalytic hydrogenation in the presence of Raney-Ni. The optical condition was temperature 130 ℃, hydrogen pressure 3.0 MPa, reaction time 7 h. The conversion rate is 95%. The yield of procaine is 83.5%. The purity is up to 98%. The product was determined by UV, IR, and diazotization titration for qualitative and quantitative analysis respectively. |
Key words:catalytic hydrogenation; p-nitrobenzoic acid-2-(diethylamino)ethyl ester; procaine; Raney-Ni |
