This invention provides novel compositions comprising aryl phosphonic or phosphinic acids substituted with more than one sulfo radical. These novel compounds may be reacted with tetravalent metal ions to provide polymers having an inorganic backbone, which polymers are useful as acid catalysts.
摘要:
Dyes of the formula ##STR1## are disclosed which are useful in dyeings where the phosphonic acid group serves both as a water-solubilizing group and as a group capable of reacting to bond covalently with the fiber to be dyed. Application of the dyes to cellulose results in reactive dyeing by immobilization of the dye as a cellulose phosphonate ester. The dye substituent is a chromophore, e.g. an anthraquinone or azo chromophore, while R may be hydrogen or lower alkyl.
摘要:
Pyro-methyl phosphonic acid (methyl phosphonic acid monoanhydride) is obtained in a high degree of purity and a yield approaching 100% of theory by the pyrolysis of dimethyl hydrogen phosphite in liquid phase. The pyrolysis product is then converted to methyl phosphonic acid by boiling with water. If desired, the resulting aqueous acid solution may be directly converted to a salt, e.g., to monoammonium methyl phosphonate by the addition of one mole of ammonia per mole of methyl phosphonic acid, or water may be evaporated from the aqueous acid solution and crystalline methyl phosphonic acid may thus be recovered.

摘要:
P-Xylylenediphosphonic acid groups connected through the aromatic ring to a variety of chromophores provide a class of novel dyes of the general formula ##STR1## wherein "Dye" represents the chromophore. These dyes may be covalently bonded to fibers and other substrates containing hydroxyl, amino, or thiol groups to form phosphonic acid esters or amides by reaction in the presence of a carbodiimide such as cyanamide or dicyandiamide.
