Abstract: Continuous gas phase partial oxidn. of an organic cpd. (I) with heterogeneous catalyst in an oxidn. reactor uses a charge gas mixt. contg. (I) O2 and an inert diluent gas (II), which consists partly of combustible gases (IIA). The novelty is that the (IIA) fraction of (II) in the prod. gas stream leaving the oxidn. reactor is not recycled to partial oxidn. but used in another chemical reaction.

Abstract: In continuous gas phase oxidn. of C3H6 to acrolein (I) and/or acrylic acid (II) with heterogeneous catalyst in an oxidn. reactor, the charge gas mixt. (III) contains only inert diluent gas(es) (IIIA) in addn. to C3H6 and O2 and (pt. of) (IIIA) is sepd. from the prodn. gas mixt. and recycled to the oxidn. reactor. The novelty is that (IIIA) consists of over 85 vol. % 1-5C satd. hydrocarbon(s).
