Abstract: The invention concerns the production of 3-pentenic acid esters by carbonylation of alkoxybutenes in the presence of a catalyst and a solvent at high temperature and pressure: at least one C1-C10 alkoxybutene, in which the alkoxy group is in the allyl position relative to the double bond, is converted with carbon monoxide at a temperature in the 60-140 ~C range and a carbon monoxide partial pressure in the 3-30 MPa range, in the presence of a palladium-based catalyst.

Abstract: The invention relates to a method for the preparation of esters of the 3-pentene acid by which alkoxybutenes are carbonylized in the presence of a catalyst and solvent at elevated temperature and pressure. These esters are intermediate compounds for the preparation of adipinic acid, caprolactam and caprolactone. The process occurs by the reaction between at least one C1-C10-alkoxybutene where the alkoxygroup is found in allyl position to the double bond with carbon monoxide at temperatures ranging from 60 to 140 deg.C, partial pressure of the carbon monoxide from 3 to 30 MPa and in the presence of a catalyst based on palladium. 4 claims

Abstract: A process is disclosed for preparing mixtures of mixed-alkylated methylolated 4,5-dihydroxy-imidazolidin-2-ones by reacting methylolated 4,5-dihydroxy-imidazolidin-2-one (DMDHEU) with a monovalent C1-5-alcohol and a polyol selected in the group which comprises ethylene glycol, diethylene glycol, 1,2and 1,3-propylene glycol, 1,2-, 1,3- and 1,4-butylene glycol, glycerin and polyethylene glycols of formula HO(CH2CH2O)nH, in which 3n20. The monovalent C1-5-alcohol and the polyol are used in an amount of 0.1 to 2.0 molar equivalents each, with respect to DMDHEU, and the reaction is carried out at temperatures from 20 ~C to 70 ~C at a pH value from 1 to 2.5, the pH value being set at 4 to 8 after the reaction.
