    摘要: Process for carrying out catalytic multiphase reactions in a tubular reactor, in which at least three reactants are present in three different phases, wherein the process is carried out in at least one tubular reactor, and the catalyst is present in a continuous phase, at least one reactant is present in this continuous phase, and at least two reactants are present dispersed in the continuous phase and the loading factor B of the tubular reactor is equal to or greater than 0.2. In particular, the multiphase reaction is a hydrocarboxylation of at least one olefin to a carboxylic acid.

    摘要: Mixtures of isomeric dialkyl phthalates that have a desired viscosity are prepared by esterifying phthalic acid or phthalic anhydride with a mixture of isomeric alkyl alcohols having a certain carbon number of carbon atoms, where the molar fraction of each alkyl alcohol isomer of the isomeric alcohol mixture is determined, and where the viscosity parameter of each alkyl alcohol isomer of the alcohol mixture, which, upon reacting with phthalic acid or phthalic anhydride, results in a mixed isomer dialkyl phalate ester product having a specific desired viscosity, is determined in accordance with formula (I): ln(η)=Σχi*ln(ηi)   (I) where η=the calculated viscosity of a dialkyl phthalate mixture, χi=the molar fraction of an isomerically pure alcohol (i), and ηi=the viscosity parameter of isomerically pure alcohol (i).
