  • Patent number: 5389685
    Abstract: The color-stability of disinfectant formulations comprising bacteriocidal quaternary amine compounds, a non-ionic surfactant, and water is enhanced significantly by adding color-stabilizing amounts of an alkali bicarbonate. An alkali bicarbonate can be used in lieu of the art-accepted EDTA/NaOH builder in quaternary amine-based disinfectant formulations to enhance color stability without sacrificing the bacteriocidal efficacy of the formulations.

  • Patent number: 5382696
    Abstract: A method for selectively preparing dimethylamine and monomethylamine, while the production of trimethylamine is inhibited to a sufficiently low level.

  • Patent number: 5371240
    Abstract: 3-substituted thiophene compounds contaminating the analogous 2-substituted thiophene compounds, e.g. 3-acetylthiophene contaminating 2-acetyl thiophene, are removed by a selective electrophilic substitution process, e.g. bromination, followed by fractional distillation. It has been found that electrophilic substitution as exemplified by bromination is highly selective towards the 3-substituted thiophenes, yielding compounds of significantly higher molecular weights for separation purposes, to give high purity 2-substituted thiophene compounds.
