Abstract: A process for preparing acrylic acid or methacrylic acid comprises(a) preparing a gaseous product mixture having essentially the composition of a reaction mixture of the catalytic gas phase oxidation of C3-/C4-alkanes, -alkenes, -alkanols and/or -alkanals and/or precursors thereof to form acrylic acid or methacrylic acid, characterized by(b) condensing said product mixture,(c) crystallizing acrylic acid or methacrylic acid from the solution obtained in step (b), and(d) removing the resulting crystals from the mother liquor.

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: A PROCESS FOR PREPARING ACRYLIC ACID OR METHACRYLIC ACID COMPRISES PREPARING A GASEOUS PRODUCT MIXTURE HAVING ESSENTIALLY THE COMPOSITION OF A REACTION MIXTURE OF THE CATALYTIC GAS PHASE OXIDATION OFC3-/C4- ALKANES,- ALKENES, -ALKANOLS AND/OR -ALKANALS AND/OR PRECURSORS THEREOF TO FORM ARCYLIC ACID METHACRYLIC ACID. ISOLATION OF ACRYLIC ACID OR METHACRYLIC ACID FROM THE GASEOUS PRODUCT MIXTURE IS ACHIEVED BY THE PROCESS CONTAINING FOLLOWING STEPS :(A) CONDENSING SAID GASEOUS PRODUCT MIXTURE, (B) CRYSTALLIZING ACRYLIC ACID OR METHACRYLIC ACID FROM THE SOLUTION OBTAINED IN STEP (A), (C) REMOVING THE RESULTING CRYSTALS FROM THE MOTHER LIQUOR, AND (D) RECYCLING AT LEAST A PORTION OF SAID MOTHER LIQUOR FROM STEP (C) INTO STEP (A).
