摘要： A continuous process for preparing (meth)acrylates of C10-alcohol mixtures by reaction of glacial (meth)acrylic acid with an isomer mixture of C10-alcohols composed of 2-propylheptanol as the main isomer and at least one of the C10-alcohols 2-propyl-4-methylhexanol, 2-propyl-5-methylhexanol, 2-isopropylheptanol, 2-isopropyl-4-methylhexanol, 2-isopropyl-5-methylhexanol and/or 2-propyl-4,4-dimethylpentanol, and the use of a diester of dicarboxylic acids which have been esterified with N-oxyl-containing compounds as polymerization inhibitors in such a process.

摘要： In a process for preparing (meth)acrylic esters (E) of polyalkoxy-containing alcohols which comprises reacting polyalkoxy-containing alcohols (P) of formula (I) where R1 is hydrogen, a hydroxyl group or a straight-chain or branched, saturated or unsaturated alcohol of 1 to 30 carbon atoms, R2 and R3 are each independently H or methyl, and m and n are each independently an integer between 0 and 100, with the proviso that m and n cannot both be 0, with a (meth)acrylic anhydride (A) in the presence of at least one basic catalyst (K) having a pKB value of not more than 7.0 and of at least one sterically hindered polymerization inhibitor, the reaction mixture is quenched with a C1-C6 alkanol after the reaction has ended.

摘要： A process for recharging the reaction tubes of a tube bundle reactor with a new fixed catalyst bed, in which a heterogeneously catalyzed partial gas phase oxidation of an organic compound had been performed beforehand in a preceding fixed catalyst bed comprising Mo-comprising multielement oxide active compositions to form a steam-comprising product gas mixture, in which, before the recharge, solid deposit which had been deposited on the tube inner walls and comprises molybdenum oxide and/or molybdenum oxide hydrate is brushed away with the aid of a brush.
