Abstract
Hydrolysis of cyanopyridine may be reduced by use of picoline as a predominately non-aqueous quench fluid. The picoline quench fluid may also be a reactant in the manufacture of cyanopyridine.
Claims6
A method of quenching gaseous reaction mixtures, comprising the step of:
- supplying a reaction mixture that contains predominately 2-cyanopyridine;
- providing a quench fluid that contains predominately 2-picoline, and not more than 20% water;
- and
- contacting the reaction mixture with said predominately non-aqueous quench fluid.
