Abstract

PURPOSE: To obtain the titled compound which is a raw material for agricultural chemicals, dyes, medicines, etc. in independent steps in a short time, by reacting a specific pyridine compound in the vapor phase with chlorine and anhydrous hydrogen fluoride in the presence a catalyst consisting of a fluoride of Co or Mn and a diluting agent.
CONSTITUTION: A pyridine compound expressed by formula I (X1 and Y1 are H or Cl), e.g. β-picoline or 2-chloro-β-picoline, in the vapor phase is reacted with chlorine and anhydrous hydrogen fluoride in the presence of a catalyst consisting of a fluoride of Co or Mn, e.g. CoF2 or MnF3, and a diluting agent, e.g. carbon tetrachloride or nitrogen, to give a chloro-β-trifluoromethylpyridine expressed by formula II (X2 and Y2 are H or Cl; however at least one is Cl). The amounts of the catalyst and the diluting agent are 0.001W3mol and 2W15mol based on one mole raw material respectively. The reaction temperature is 350W600°C.
