Abstract: THE PRESENT INVENTION RELATES TO A METHOD FOR RECOVERING COMPONENTS FROM A LOW BOILER MIXTURE, WHICH ARISES IN THE DISTILLATION OF HYDROGENATION EFFLUENTS FROM THE PRODUCTION OF POLYMETHYLOLS, BY MULTI-STAGE DISTILLATION OF THE LOW BOILER MIXTURE, WHICH CONTAINS A TERTIARY AMINE, WATER, METHANOL, POLYMETHYLOL OF THE FORMULA (I), METHYLOLALKANAL OF THE FORMULA (II), ALCOHOL OF THE FORMULA (III), AND AN ALKANAL HAVING A METHYLENE GROUP IN THE ?-POSITION WITH RESPECT TO THE CARBONYL GROUP, AND IN WHICH R STANDS FOR ANOTHER METHYLOL GROUP OR AN ALKYL GROUP HAVING 1 TO 22 C ATOMS OR AN ARYL OR ARALKYL GROUP HAVING 6 TO 22 C ATOMS INDEPENDENTLY OF EACH OTHER IN EACH CASE, WHEREIN IN A FIRST DISTILLATION STAGE, THE LOW BOILER MIXTURE IS SEPARATED INTO A HIGHER BOILING, PREDOMINATELY WATER-RICH FRACTION AND INTO A LOWER BOILING AQUEOUS, ORGANIC FRACTION CONTAINING THE TERTIARY AMINE, AND IN THE SECOND DISTILLATION STAGE, THE AQUEOUS, ORGANIC FRACTION FROM THE FIRST DISTILLATION STAGE IS SEPARATED INTO A FRACTION PREDOMINANTLY CONTAINING AMINE AND ANOTHER AMINE-DEPLETED FRACTION, CHARACTERIZED IN THAT THE TERTIARY AMINE IS TRIMETHYLAMINE OR TRIETHYLAMINE AND THE SUMP TEMPERATURE IN THE SECOND DISTILLATION STAGE IS 110°C AND MORE.

Abstract: THE PRESENT INVENTION RELATES TO A PROCESS FOR PURIFYING CRUDE POLYMETHYLOL WHICH COMPRISES POLYMETHYLOL OF THE FORMULA (I) IN WHICH EACH R IS INDEPENDENTLY A FURTHER METHYLOL GROUP OR AN ALKYL GROUP HAVING 1 TO 22 CARBON ATOMS OR AN ARYL OR ARALKYL GROUP HAVING 6 TO 22 CARBON ATOMS, AND ALSO HYDROXY ACID OF THE FORMULA (IV) IN WHICH EACH R IS INDEPENDENTLY AS DEFINED ABOVE, WHICH COMPRISES PERFORMING THE PURIFICATION IN A DISTILLATION COLUMN, THE BOTTOM OF THE DISTILLATION COLUMN BEING CONNECTED TO AN EVAPORATOR WITH A SHORT RESIDENCE TIME. THE PRESENT INVENTION FURTHER RELATES TO A COMPOSITION COMPRISING POLYMETHYLOL AND 1 TO 10 000 PPM BY WEIGHT OF AN ESTER OF POLYMETHYLOL AND OF A HYDROXY ACID AND TO THE USE THEREOF.

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
