Abstract
Pyridine was determined by catalytic reduction over Raney nickel and subsequent azotometry of secondary amines. Catalytic reduction of pyridine was completed merely by shaking it with Raney nickel W-6 in a test tube, omitting the general procedure of introducing hydrogen. Thus, pyridine, isonicotinic acid, N-hydroxymethyl-isonicotinamide, and 2-benzyl-aminopyridine was determined with an accuracy within 1.3%.
