  • Patent number: 5037968
    Abstract: Keto compounds in which to the carbon atom in the neighboring position to the keto compounds there is bonded at least one strongly electron attracting substituent and/or in which there is conjugating with the carbon-oxygen-double bond of the keto group a .pi.-electron system have the ability of interacting selectively with the anions of oxa acids yielding adducts, chelates or complexes.Provided that in the corresponding keto compounds the keto group is a part of a chromophore, then the shifting of the absorption in the visible range or the ultraviolet range of the wave lengths is observed, compared with the corresponding absorption of the free keto compound.The corresponding keto compounds are used for the determination of the anions of the oxa acids and they e.g. can be the ion sensitive component of a corresponding ions sensitive part for the determination of said anions. Several of said keto compounds can be also used as color indicator for the anions of the oxa acids.

  • Patent number: 4749784
    Abstract: The specification describes a new group of alkanol substituted disazo compounds that are useful in dyeing polyamide textile fibers in orange hues. The new compounds are compatible with several acid blue dyes and several acid red dyes that are commercially important as dyes for nylon. The new compounds are particularly well suited for use as the "yellow" component in trichromatic systems for dying polyamide carpeting and other textiles. The new compounds are relatively inexpensive to make and have outstanding application and fastness properties. Other aspects of the specification are concerned with a method of making the new compounds and with a method of dyeing polyamides with said compounds and to the novel dyed polyamides resulting from the use of the new group of compounds as dyes.
