Abstract
a -Hydroxy-dialdehydes of the formula <FORM:0928148/IV(a)/1> where R and R1 are as defined below, are prepared by reacting an aldehyde of the formula <FORM:0928148/IV(a)/2> where R represents an unsubstituted or alkyl substituted ethylene group having both its carbon atoms in the ring and R1 represents a hydrogen atom or an alkyl group, with water in the presence of a solid cation exchange resin having functional groups in the hydrogen form and an acidity at least equal to that of an acid of pK 7. The solid cation exchange resin preferably has a porosity such that the fully water-swollen resin has a water content of at least 60% by weight, and the acidic groups are preferably sulphonic, carboxylic, phosphonic, phosphonous or iminodiacetic groups. A list of preferred aldehyde starting materials is given. The a -hydroxydialdehydes may be subsequently converted, for example by hydrogenation, to triols of the formula <FORM:0928148/IV(a)/3> where R and R1 are as defined above, In Examples: (1)-(3), acrolein dimer is hydrolysed to a -hydroxy-adipaldehyde using various types of resin and the product is hydrogenated to 1,2,6-hexanetriol; (4) methacrolein dimer is hydrolysed to 2,5-dimethyl-2-hydroxy-hexanedial. Specifications 725,161 and 789,952 are referred to.
