Abstract: A PROCESS FOR PREPARING ACRYLIC ACID AND/OR ACRYLATES, WHICH COMPRISES STAGE A WITH OR WITHOUT STAGES B AND C:A: COOLING A GASEOUS REACTION MIXTURE WHICH COMPRISES ACRYLIC ACID AND IS OBTAINED IN THE GAS-PHASE OXIDATION TO PREPARE ACRYLIC ACID, USING AN INERT HIGH-BOILING SOLVENT, TO GIVE A GASEOUS MIXTURE COMPRISING ACRYLIC ACID;B: SEPARATING THE GASEOUS MIXTURE COMPRISING ACRYLIC ACID TO GIVE A LOW-BOILING FRACTION, A CRUDE ACRYLIC ACID, AND A BOTTOM PRODUCT,ANDC: ESTERIFYING THE CRUDE ACRYLIC ACID OBTAINED IN STAGE B BY MEANS OF ONE OR MORE ALKANOLS TO GIVE AN ESTERIFICATION MIXTURE COMPRISING ONE OR MORE ACRYLATES AND ONE OR MORE ACETIC ESTERS.

Abstract: Water-soluble or self-dispersing resin tanning agents are prepared by heating from 5 to 30% by weight of melamine, from 15 to 45% by weight of urea, from 20 to 35% by weight (calculated as anhydrous material) of formaldehyde and from 15 to 55% by weight of sodium bisulfite or of a corresponding amount of some other salt of sulfurous acid for from two to twelve hours in aqueous solution at 40 DEG -120 DEG C. and a pH of from 5 to 9.

Abstract: 2-Hydroxy-2,5-dihydrofuran-5-one (I) is prepd by oxidn of furan or furfuran with O2 or a gas contg O2 in a solvent at 70 degrees C while irradiating with light, the novelty residing in the fact that the solvent is distilled from the reaction mixt at 70 degrees C and (I) is isolated from the residue by crystn. Prior art processes using EtOH as solvent gave the 2-ethoxy deriv, which had then be saponified. Opt. substd. (I) e.g. mucochloric acid are inters for herbicidal pyridazones.

Abstract: A fungicidal composition which is a synergistic mixture of 2-(methoxycarbamoyl)-benzimidazole and an N-substituted phthalimide having a combined fungicidal action greater than the sum of actions of the individual components. The composition is especially useful in preventing fungus growth on seeds and plants.
