Abstract: Process for the catalytic hydrogenation of methylolalkanals of the general formula where R 1 and R 2 are each, independently of one another, a further methylol group or an alkyl group having from 1 to 22 carbon atoms or an aryl or aralkyl group having from 6 to 33 carbon atoms, in the liquid phase by means of hydrogen over a hydrogenation catalyst, wherein hydrogen is used in a molar ratio to methylolalkanal of greater than 1.

Abstract: La invención se relaciona a un proceso para preparar compuestos de polimetilol de la fórmula (I) en la cual R es en cada caso independientemente un grupo metilol o un grupo alquilo adicional que tiene de 1 a 22 átomos de carbono o un grupo arilo o aralquilo que tiene de 6 a 22 átomos de carbono, al condensar aldehídos que tienen de 2 a 24 átomos de carbono en una reacción aldol con formaldehído utilizando aminas terciarias como un catalizador para dar alcanalos de la fórmula (II) en la cual R es en cada caso independiente como se define anteriormente, y la hidrogenación subsiguiente de la misma. Lo que es especial e ingenioso acerca de este proceso es que la reacción aldol se lleva a cabo con una solución acuosa de formaldehído que tiene un contenido de ácido fórmico de

Abstract: PROCESS FOR PREPARING POLYALCOHOLS FROM FORMALDEHYDE WITH A LOW FORMIC ACID CONTENT 5 - II@2 (HOCHA- C (HOCH2)- C - CHO (11) 10 I R2 THE INVENTION RELATES TO A PROCESS FOR PREPARING POLYMETHYLOL COMPOUNDS OF THE FORMULA (1) IN WHICH R IS IN EACH CASE INDEPENDENTLY A FURTHER METHYLOL GROUP OR AN ALKYL GROUP HAVING FROM 1 TO 22 CARBON ATOMS OR AN ARYL OR ARALKYL 15 GROUP HAVING FROM 6 TO 22 CARBON ATOMS, BY CONDENSING ALDEHYDES HAVING FROM 2 TO 24 CARBON ATOMS IN AN A1DOL REACTION WITH FORMALDEHYDE USING TERTIARY AMINES AS A CATALYST TO GIVE ALKANALS OF THE FORMULA (11) IN WHICH R IS IN EACH CASE INDEPENDENTLY AS DEFINED ABOVE, AND THE SUBSEQUENT HYDROGENATION THEREOF. WHAT IS SPECIAL AND INVENTIVE ABOUT THIS PROCESS IS THAT THE ALDOL REACTION IS 20 CARRIED OUT WITH AN AQUEOUS FORMALDEHYDE SOLUTION HAVING A FORMIC ACID CONTENT OF

Abstract: The object of the present invention is a method for producing e-caprolactone in a purity greater than 99% by cyclization of 6-hydroxycaproic acid ester in the liquid phase at 150 to 400°C and 1 to 1020 hPa abs., separation and condensation of the compounds which are volatile under cyclization conditions, characterized in that the remaining sump product of the cyclization is thermally treated in at least one further reactor, volatile compounds are separated and condensed, and e-caprolactone is obtained from the condensate by distillation.
