Abstract
The present invention relates to a method for synthesizing bio-based pyridine and picolines, said method including at least the following steps: a first step involving subjecting a glycerol filler, created from the methanolysis of vegetable oils or animal fats, to a dehydration reaction leading to acrolein; a second step involving partial condensation of the effluent from the first step so as to separate a water-rich flow as well as an acrolein-rich flow; and a third step involving reacting the acrolein from the preceding step with acetaldehyde in the presence of ammonia so as to obtain, by means of a condensation reaction, the bio-based pyridine and picolines.
