SELECTIVE ALDOLIZATION OF ACETONE TO DIACETONEALCOHOL WITH A SOLID BASIC CATALYST

摘要

selective aldolization of diacetone alcohol acetonea solid base catalyst. the aldolization havecharacterized by the fact that the solid base catalyst atgeneral formula (ii):(mg2 +) 1-x (al3 +) x (oh) 2] + [(oh -) x x x x x x x x x x x x x x x x x x x x x (h2o) n] (ii)with 0.20 ~ x ~ 0.33, n has a value of less than 1.a catalyst having a similar crystal structure defined.the hydrotalcite or the meixnerite. and...process for the preparation of the catalyst (ii).
