    摘要： A method to manufacture a mixture of aliphatic hydroxyesters, especially from isobutyric aldehyde, is characterized by that the isobutyric aldehyde condensation reaction is carried out in the presence of a mixture of sodium hydroxide and sodium isobutyrate as catalyst in a weight ratio of 3:1, first at 58-60% conversions of isobutyric aldehyde to 2,2,4-trimethyl-1,3-pentanediol isobutyrate at temperatures in the range 58-62°C during 8-12 minutes and then at 68-72% conversions of isobutyric aldehyde to 2,2,4-trimethyl-1,3-pentanediol isobutyrate at temperatures in the range 88-92°C during 3-7 minutes whereupon, from a mixture of 3-hydroxy-2,2,4-trimethylpentyl isobutyrate and 3-hydroxy-2,2-dimethyl-1-(1-methylethyl)propyl isobutyrate, an aqueous solution of the catalyst is separated by allowing to stand and elution from the organic phase of the mixture after the condensation reaction while the process of distillation of the remaining portion of the mixture after the condensation reaction is carried out in four steps.
