  • Thermostable hydroxystyrylaza compounds
    Patent number: 4600767
    Abstract: Thermostable hydroxystyrylaza compounds are prepared by reacting methylated pyridines and/or pyrazines with one or more monohydroxy aromatic aldehydes having the ortho and para positions to the hydroxy group block with groups inert to condensation reactions. These compounds are useful to make unsaturated derivatives which can cure into high temperature resistant polymers and/or laminates without giving off condensation products.

  • Operation and regeneration of permselective ion-exchange membranes in brine electrolysis cells
    Patent number: 4381230
    Abstract: Methods of membrane regeneration of permselective ion-exchange membranes of a brine electrolysis cell are greatly improved when the cells are fed brine which contains little or no carbon dioxide, carbonate anions or bicarbonate anions during normal electrolysis and when the methods of membrane regeneration are those wherein at least one liquid solution contacts the membrane and the pH of that solution is below that of the pH of the electrolyte in contact with the membrane during normal electrolysis.
