brown.

(b) Distillation range. When 100 ml are

distilled in the manner described for

pyridine bases, not more than 5.0 ml

should distill below 90 °C.

(c) Pyrrol reaction. Prepare a 1.0 per-

cent solution of bone oil in 95 percent

alcohol. Prepare a second solution con-

taining 0.025 percent bone oil by dilut-

ing 2.50 ml of the first solution to 100

ml with 95 percent alcohol. Dip a splin-

ter of pine, previously moistened with

concentrated hydrochloric acid, into 10

ml of the 0.025 percent bone oil solu-

rates into a flocculent precipitate on

standing several minutes. Add 5.0 ml of

the 0.025 percent bone oil solution to

5.0 ml of a 2.0 percent alcoholic solu-

tion of mercuric chloride. A faint tur-

bidity appears after several minutes.

is formed that is not dissolved by hy-

drochloric acid when several drops of a

1 N barium chloride solution are added

to 10 ml of a solution of the alkaloid.
