Abstract: In the prodn. of carbonate esters (I) of the formula O=C(-O-R)2 (in which R is an organic radical with at least 2C) by ester interchange of dimethyl carbonate (II) with an alcohol R-OH, the MeOH formed is removed azeotropically with a 5-8C (cyclo)paraffin. The process is economical and does not necessitate the use of special conditions. (I) are intermediates for the prodn. of pharmaceuticals and plant protection agents.

Abstract: Continuous process for preparing carboxylic acids by reacting (cyclic) olefins or (cyclic)alkanols with CO under press. and in the presence of H2SO4 at 0-80 degrees C, then hydrolysing the reaction product with ice-water, is improved when the reaction is carried out in a cyclic system in which the reaction mixt. is continuously recycled to the reaction zone via an external circuit. The acids are used to prepare lubricants, siccatives, esters (solvents) and peroxy esters (polymsn. initiators). Provides better removal of reaction heat with a uniform temp. profile throughout the reaction so less by-product formation. Less acid is needed. Pref. starting materials are 3-20C olefins, 5-12C cycloolefins, 2-20C alkanols or 5-12C cycloalkanols esp. (di)isobutylene, 2-ethyl-hexanol, alpha-methylpentanol or 6-10C olefin fractions.

Abstract: 3-Phenylpropanals and 4-phenylbutanals having the formula: (where R1 is OH, 1-4C alkoxy or acyloxy; R2 is H or, as R1, OH, 1-4C alkoxy or acyloxy; R1 and R2 together may form a methylenedioxy gp.; X is formyl if Y is H and T is formyl if X is H), have odoriferous props and are inters for dyes and plant protective agents. They are prepd. by hydroformylation of olefines having the formula with CO and H2, esp. in 1:4 to 4:1 vol. ratio and =100 molar excess w.r.t. (II), at 50-180 (60-130) degrees C under 20-1500 (150-700) atmos. excess press., in the presence of Ph carbonyl complexes as catalysts, advantageously using 0.5-100 p.p.m. Rh w.r.t. (II), opt. in solvents.
