摘要： Solutions of hydroquinone are stabilized against deterioration in color and odor with age by the addition to the solution of small amounts of citric acid. Up to about 1 percent citric acid by weight of the solution may be used, although it is preferred that this amount be between 0.005 percent and 0.05 percent.

摘要： GRANULAR PENTACHLOROPHENOL SUCH AS THAT USED FOR PRESERVING WOOD SLOWLY SUBLIMES DURING STORAGE TO FORM A FINELY CRYSTALLINE DUST WHICH IS HIGHLY IRRITATING TO SKIN AND MUCOUS MEMBRANES AND WHICH ADVERSELY AFFECTS THE APPEARANCE OF THE PRODUCT. SUCH SUBLIMATION AND VAPORIZATION OF RESIDUAL ACID FROM THE PRODUCT ARE ESSENTIALLY AVOIDED BY ADDING TO THE MOLTEN PENTACHLOROPHENOL PRIOR TO THE GRANULATING STEP A SMALL AMOUNT OF AN AMINE OF LOW VOLATILITY. ALKANOLAMINES SUCH AS DIETHANOLAMINE AND TRIETHANOLAMINE ARE PARTICULARLY SUITABLE FOR THE PURPOSE.

摘要： A method for reducing pollutant discharge in phenol acetone production, comprising at least one of the following steps: (A) collecting phenolic wastewater generated by a phenol-acetone plant, adjusting the pH value to acidic, and performing extraction and recovery on the phenols in wastewater using cumene as an extracting agent; (B) reducing the acetone content in the wastewater from a column bottom by means of optimizing the process of an acetone refining column; (C) treating the wastewater from the column bottom of the acetone refining column by using a permselective membrane, and recovering alkali; (D) neutralizing the wastewater obtained from step (C), mixing the neutralized wastewater with a condensation liquid at the top of a cumene oxidation column, and carrying out a detoxification treatment; (E) carrying out an oil separation treatment on total discharged wastewater from the phenol-acetone plant, and recovering organic matters comprising hydrocarbons; and (F) carrying out a biological treatment, a coagulation sedimentation treatment and a reinforced degradation treatment on the wastewater after undergoing the oil separation treatment. The method has at least one of characteristics of being capable of recovering resources, increasing product yield, reducing pollutant discharge, having low cost in wastewater treatment, and having stable quality for water output.
