| titleOfInvention | Preparation of uv grade synthetic pyridine |
| abstract | A method of preparing UV-grade synthetic pyridine nfrom a pyridine-containing reaction product mixture nwhich also contains at least one other compound which is nUV absorbing to a sufficient extent that said pyridine nmixture is not UV grade, said mixture being obtained nfrom the condensation reaction, over an effective ncatalyst, of one of more aldehydes and/or ketones with none or more amines and/or ammonia, comprises recovering nfrom said mixture a pyridine-water azeotrope effective nto separate pyridine therefrom sufficiently free of UV-nabsorbing compounds to be UV grade. |
