Abstract: Production of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate and 2,2,4-trimethyl-1,3-pentanediol diisobutyrate comprises reaction of isobutyraldehyde in the presence of an aqueous alkalimetal hydroxide, separation of the aqueous phase and reaction of at least a portion of the mixture with isobutyric acid under conditions of esterification to form 2,2,4-trimethyl-1,3-pentanediol diisobutyrate. Production of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate and 2,2,4-trimethyl-1,3-pentanediol diisobutyrate comprises: (A) reaction of isobutyraldehyde in the presence of an aqueous alkalimetal hydroxide as a basic catalyst, to give an organic phase comprising a mixture of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate and 2,2,4-trimethyl-1,3-pentanediol, and an aqueous phase comprising the alkalimetal hydroxide and alkalimetal isobutyrate; (B) separation of the aqueous phase; (C) optional removal of a portion of the resulting mixture from the process and/or separation of the mixture into its components followed by optional removal of the separated 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate; (D) reaction of at least a portion of the mixture from step (B) with isobutyric acid under conditions of esterification to form 2,2,4-trimethyl-1,3-pentanediol diisobutyrate; and (E) optional recovery of the product.

Abstract: Alcohols are prepared by the catalytic hydrogenation of the corresponding carbonyl compounds at elevated temperatures and at superatmospheric pressure in the liquid phase by a process in which the catalyst used contains copper on an SiO2-containing carrier in the presence or absence of one or more of the elements magnesium, barium, zinc and chromium.

Abstract: Hydroformylation of 2-8C olefins comprises: (a) catalytically reacting an olefin containing saturated hydrocarbon (SHC) with CO and H2; (b) separating off a stream of unreacted olefin and SHC and contacting it with an olefin-selective membrane to give an olefin-enriched permeate and an olefin-depleted retentate; and (c) recycling at least part of the permeate back to the reaction zone.

Abstract: Formaldehyde is removed by distillation from reaction solutions containing a methlolated alkanal which was obtained from the reaction of formaldehyde with an alkanal which has at least one acidic hydrogen atom alpha to the carbonyl function or from the reaction of a 2-alkylacrolein or acrolein with water and formaldehyde, by a process in which this reaction was carried out in the presence of catalytic amounts of organic amine. The process permits the improved removal of formaldehyde from the reaction mixture and furthermore facilitates the hydrogenation of the alkanals thus obtained to give polyols.

Abstract: The invention relates to a method, whereby the colour number of polyhydric alcohols, in particular, trihydroxymethylpropane, can be significantly improved by hydrogenation. The method is characterized in that an alcohol is used in the hydrogenation, which has been previously purified by distillation. The conventional catalysts for hydrogenation are used as catalysts, preferably copper, nickel, palladium or ruthenium.

Abstract: Catalysts containing copper as an active component ,and used in the hydrogenation of methylol-aldehydes to methylol-alcohols, are regenerated in an oxygen-containing medium and activated prior to re-use in a hydrogen-containing medium. An Independent claim is included for use of the catalyst regeneration process is in the hydrogenation of hydroxypivalaldehyde, 2,2-dimethylolbutanal, 2,2-dimethylolpropionaldehyde, 3-hydroxypropionaldehyde and/or trimethylolacetaldehyde.
