  • Process for the catalytic treatment of wastewater
    Patent number: 5205906
    Abstract: A process is presented for the treatment of wastewater containing non-volatile pollutants and volatile chemically oxidizable organic and inorganic pollutants. The process combines efficient evaporation to concentrate the non-volatile compounds and a catalytic oxidation reaction to convert the volatilized organic and inorganic pollutants. A condensate product may be obtained by treating wastewater according to the inventive process that is of distilled water quality and substantially free of minerals and organics.

  • Melt preparation of 6TA/6IA polymers with phosphorus compound to reduce ammonia formation
    Patent number: 4113708
    Abstract: An improvement in the process for preparing random copolyamides by the melt polymerization of a mixture of hexamethylenediammonium terephthalate and hexamethylenediammonium isophthalate is described. The improvement comprises accomplishing the melt polymerization in the presence of a small amount of a certain phosphorus compound, such as benzene phosphinic acid, whereby ammonia formation during polymerization is reduced.
