摘要： 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.

摘要： Clear, high-density fluids suitable for use as well completion, packing, and perforation media comprise aqueous solutions of zinc bromide and calcium bromide having densities lying in the range of about 14.5 up to about 18.0 pounds per gallon and measured pH's lying in the range of about 3.5 up to about 6.0. Optionally, such fluids may also comprise calcium chloride and/or a soluble film-forming amine-based corrosion inhibitor. Such fluids under conditions of ordinary use exhibit low corrosion rates and have crystallization points lying well below the range of temperatures under which they are used.
