METHOD OF PRODUCING 3,5-DIMETHYLPYRIDINE Russian patent published in 2017 - IPC C07D213/06

Abstract RU 2608734 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 3,5-dimethylpyridine. Method involves reaction of propanol-1, formaldehyde and ammonia in presence of granulated binder-free zeolite Y-BS in Η-form at 250–450 °C and volume rate of supply of raw material (w), equal to 2-7 h^-1, molar ratio of propanol-1: formaldehyde: ammonia is 1.0:0.2–2.0:1.5–5.

EFFECT: use of present method enables to obtain 3,5-lutidine with high volume rate of supply of raw material with high output.
