Abstract: A DESCRIPTION IS GIVEN OF A PROCESS FOR PREPARING METHYL FORMATE (16) BY REACTING EXCESS METHANOL (3) WITH CARBON MONOXIDE UNDER SUPERATMOSPHERIC PRESSURE AND AT ELEVATED TEMPERATURE IN THE PRESENCE OF ALKALI METAL METHOXIDE OR ALKALINE EARTH METAL METHOXIDE AS CATALYST IN A PRESSURE-RATED REACTOR (1), IN WHICH THE USE OF AT LEAST TWO REACTOR ELEMENTS, PREFERABLY OPERATED IN COUNTERCURRENT, AT ABOUT 100°C AND A PRESSURE OF ABOUT 10 MPA (100 BAR) IN COMBINATION WITH A SOLIDS-FREE DESALTING OF THE REACTION PRODUCT MAKES POSSIBLE VERY ECONOMICAL, LARGELY TROUBLE-FREE PRODUCTION OF METHYL FORMATE (16) IN ANY DESIRED QUALITY AND WITH A VERY GOOD PRODUCTION CAPACITY. FURTHERMORE, THE PROCESS FOR SOLIDS-FREE DESALTING ARID APPARATUSES (19) FOR CARRYING OUT THIS PROCESS ARE DESCRIBED.(SOLE

Abstract: Acrylic and methacrylic acid can be synthesized by catalytic gas phase oxidation of 3-4C alkanes, alkenes, alcohols and/or aldehydes. This process for the production of acrylic acid or methacrylic acid comprises: (A) production of a gaseous product mixture comprising the reaction mixture arising from the (B) condensation of the gaseous product mixture (C) crystallization of acrylic acid or methacrylic acid from the resulting solution. (D) separation of the crystals from the mother liquor and (E) recycling of at least a portion of the mother liquor from (D) to (B).
