ABSTRACT:
The present invention discloses an improved method for the in situ end point determination of the oxyethylation of phenols. In the present invention, the oxyethylation reactions occur in the presence of catalysts and at temperatures in excess of 100.degree. C. The reaction end point is monitored by continuous measurements of the electrical conductivity of the reaction mixture and the reaction is terminated when a preselected rate of change of conductance is attained.
The method of the present invention may be used with complex phenolic systems wherein alkali metal hydroxides, quarternary ammonium salts, or alkali metal alkoxides are used as oxyethylation catalysts.
