• PROCESS FOR PREPARING POLYALCOHOLS FROM FORMALDEHYDE HAVING A LOW FORMIC ACID CONTENT

  The invention relates to a process for preparing polymethylol compounds of the formula (I) (HOCH 2 ) 2 —C—R 2 (I) where the radicals R 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 22 carbon atoms, by condensation of aldehydes having from 2 to 24 carbon atoms with formaldehyde in an aldol reaction using tertiary amines as catalyst to form alkanals of the formula (II) where the radicals R each independently have one of the abovementioned meanings, and subsequent hydrogenation of the latter. The particular inventive feature of this process is that the aldol reaction is carried out using an aqueous formaldehyde solution having a formic acid content of <150 ppm and preferably <100 ppm. In this way of carrying out the process, the formation of by-products can advantageously be prevented in a targeted manner and the yield of the desired polymethylol compound can thereby be increased.

  该发明涉及一种制备多羟甲基化合物的方法，其化学式为(I)(HOCH2)2—C—R2(I)，其中基团R分别独立地为另一个甲醇基团或具有1至22个碳原子的烷基基团或具有6至22个碳原子的芳香基或芳基烷基基团，通过将具有2至24个碳原子的醛与甲醛在醛缩反应中使用三级胺作为催化剂进行缩合，形成化学式(II)的脂醛，其中基团R各自独立地具有上述含义之一，并随后对其进行氢化。该方法的特殊创新特点在于，在使用含有甲醛的水溶液进行醛缩反应时，其甲酸含量小于150 ppm，最好小于100 ppm。通过采用这种方法进行处理，可以有针对性地防止副产物的形成，并从而增加所需多羟甲基化合物的产率。
