  • Method for making bisphenoxide salts
    Patent number: 4410735
    Abstract: A process is provided for making bisphenoxide salts by the flash evaporation of water from an aqueous mixture of a bisphenol and an alkali metal hydroxide. Improved control over the stoichiometry of the bisphenol and the alkali metal hydroxide in the aqueous mixture is achieved by monitoring bisphenol content in the aqueous bisphenoxide salt mixture. An extractive organic solvent for the bisphenol is used with an aliquot of the bisphenoxide salt mixture. The stoichiometric balance in the aqueous bisphenoxide salt mixture is determined by measuring the absorbance value of the bisphenol in the organic solvent phase, and comparing it to a known curve obtained by plotting known bisphenol absorbance values and equivalents of alkali metal hydroxide.

  • Chlorination of phthalic anhydride
    Patent number: 4297283
    Abstract: An aromatic compound of the class of phthalic anhydride and ortho-phthalonitrile can be monochlorinated, predominantly in the 4-position, by a vapor phase reaction involving passing chlorine and the aromatic compound through a heated zone maintained at a temperature above 350.degree. C.
