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

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: A process for greatly improving the color index of polyhydric alcohols, especially trimethylolpropane, by hydrogenation comprises using, in the hydrogenation, an alcohol which has already been purified by distillation. The catalysts used are those conventionally employed in hydrogenations, preferably copper, nickel, palladium or ruthenium catalysts.

Abstract: A process is provided for increasing the yield in the preparation of polyhydric alcohols obtained from methylolated alkanals by hydrogenation, wherein derivatives of these alcohols are decomposed by adding 5 ppm to 1% by weight, preferably 100 to 1000 ppm, of a suitable acid to an anhydrous mixture containing these derivatives, heating the mixture to temperatures of 100 to 300° C. and then separating off the polyhydric alcohol by distillation. This process makes it possible simply and efficiently to decompose compounds which boil above the polyhydric alcohol and are unwanted by-products of its synthesis.

Abstract: La invencion se refiere a un metodo para llevar a cabo la destilacion pura de trimetilolpropano que proviene de la hidrogenacion de 2,2-dimetilolbutanal a traves de las siguientes etapas: (a) reaccion de n-butiraldehido con formaldehido en presencia de cantidades cataliticas de una amina terciaria e hidrogenacion de la mezcla que se obtiene de tal manera que se forme una mezcla que contiene trimetilopropano; (b) separacion de agua metanol, trialquilamina y/o formato de trialquilamonio mediante destilacion; (c) calentamiento del residuo obtenido en (b), en vacio, a una temperatura en la cual TMP es volatil y a la cual compuestos que hierven a temperaturas mayores que la temperatura de ebullicion de TMP son disociados mientras se separa por destilacion TMP asi como compuestos que son menos volatiles que TMP; (d) destilacion del destilado obtenido en (c) mientras se separan los compuestos -menos volatiles y obtencion de TMP puro; (e) realizacion de la destilacion facultativa del TMP obtenido en (d) con el objeto de obtener TMP que tiene un indice de color alfa bajo. La invencion se refiere tambien al metodo en el cual formato de trialquilamonio es separado por destilacion mientras se conserva, a partir de mezclas brutas que consisten de alcoholes polivalentes, principalmente trimetilolpropano.
