Verfahren zur Herstellung eines Vanadium, Antimon und Zinn enthaltenden Katalysators

摘要

Disclosed is a method of making a catalyst containing vanadium antimony and tin in the oxide state which comprises making an aqueous slurry of a mixture of source batch materials comprising compounds of the elements to be included in the final catalyst followed by drying and heat calcining the mixture to an active catalyst, using as the source batch material for tin a stannous salt of a C1 to C18 acyclic, monocarboxylic acid containing no ethylenic or acetylenic carbon-to-carbon unsaturation.
