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: PF 61684Method for producing poiymethylots Abstract5 The present invention a process for recovering eornponcnfs from a low hollermixture which is obtained in the distillation of hydrogenation effluents from the prepara tion of polymethylots, by MbItistage distigation of the tow bler Modure corn-tertiary amine, water, me.thanol, pcitymethylol of the formula 0)10 methybtstkana.l of the formula Ohl(HOC H2) -- CHOR/15tthefoHC—OH20 and an alkanal with a methylene group M the a position to the carbonyl “cup,and in whir:1-k itrach R is independently a further methyloi group or an alkyl group having Ito 22 carbon atoms or an aryl or aralkyl group hawing 6 to 22 carbon Wan%a first disttlation stage invohil eporating the >ow bailer mixture into a higher-b predornioarWy water-rich fraction and into a lower-boiling aqueous organic traction compristng the tertiary amine,and the .wiond disttitation stage invcMng separatlng the aqueous oruanic fraction from the first dist:gat-ion stage into a predominantly amine-containing fraction and a further arnirdepletted fraction,iivherein the tartan/ amine is frimeihyarnine or thethyiantine, and the bottom tempema tore in the second distillation stage is tificC and mom.
