    Abstract: Novel rhodium based amorphous metal alloys having the formula RhrAa where: A is B, P, As and mixtures thereof; r is from about 50 to 96 percent; and a is from about 4 to 50 percent. Novel rhodium based amorphous metal alloys are also based on the formula RhrBbDd where: D is Ir, Pd, Ru, Ti, Zr, Nb, Ta, Y, Hf and mixtures thereof; r is from about 50 to 96 percent; b is from about 4 to 50 percent; and d is from about 0 to 60 percent; and r + b + d = 100. Novel process for the generation of halogens from halide-containing solutions can be performed by employing the rhodium based metal alloys of the present invention.

    Abstract: (4856) PREPARATION OF MALEIC ANHYDRIDE FROM FOUR CARBON HYDROCARBONS Catalyst comprising the combined oxides of vanadium and at least one element selected from the group consisting of boron, niobium, tantalum, antimony, tungsten and chromium have been found to be especially effective in the oxidation of n-butane, n-butenes and butadiene, or a mixture thereof with molecular oxygen in the vapor phase to yield maleic anhydride. The catalysts of the present invention may be further promoted with additional elements to enhance activity, stability and selectivity. The reaction with n-butane gives an especially pure product in good yield and selectivity.
