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
