SELECTIVE ALDOLIZATION OF ACETONE IN DIACETONEALCOOL BY A SOLID BASIC CATALYST

摘要

The aldolisation is characterized in that the solid basic catalyst has the following general formula (II): ## STR1 ## with 0.20 = x = 0, 33, n having a value of less than 1, this catalyst having a defined crystalline structure, analogous to that of hydrotalcite or Meixnerite. BR/ Process for the preparation of catalyst (II). / P
