Abstract

Gels containing molybdenum and iron and optionally other metals, are useful in the production of catalysts or as optical filters. They are produced by conducting essentially a solid - solid reaction between a compound of molybdenum, e.g. ammonium molybdate, and a ferric compound, e.g., ferric nirate, thereby obtaining the same ratio of molybdenum and ferric contents in the gels, as used in the starting materials. Furthermore, the resultant gels are highly homogeneous, and when used as catalysts, the yields of the process are up to plus 99%.
