B-NICOTYRINE Chemical Properties,Usage,Production
Description
The occurrence of this alkaloid in the cigar type of tobacco has been reported by Wenusch and subsequently confirmed by Spath and Kesztler. It forms a colour_x0002_less oil when pure and yields crystalline salts and derivatives, e.g. the p1atinichloride, m.p. 158°C; picrate, m.p. 170-1 °c and the methiodide, m.p. 2l1-3°e. It may also be prepared from nicotine by oxidation with silver oxide, silver acetate or potassium ferricyanide. With Zn and HCI, the base is reduced to nicotine and 4:5-dihydronicotyrine, b.p. 244-6°C, yielding a dipicrate, m.p. l64°e. In the presence of prepared Pt02, the latter may be further reduced to dihydrometanicotine, the dipicrate of which has m.p. 161-2°C. Nicotyrine may be converted directly into nicotine in one operation by controlled hydrogenation in the presence on Pd-e
Chemical Properties
Clear Light Red-Brown Oil
Uses
Nicotryrine is an alkaloid derived from the dehydrogenation of nicotine and its analog, nornicotine. An alkaloid occurring in cigaret smoke.
Definition
ChEBI: Nicotyrine is a member of pyridines.
