  Acetalization of Heptanal over Al-SBA-1 molecular sieve

  摘要：

  Al-SBA-1 (Si/Al = 40 80 and 120) and Al Mg-SBA-1 (Si/(Al + Mg)= 40 and 80) molecular sieves were synthesized and characterized Acetalization of n-heptanal with methanol was studied under autogenous pressure between 80 and 150 C Since protonation of n-heptanal was fast addition of methanol to the same formed hemiacetal slowly whereas conversion of hemiacetal to acetal was fast The catalysts exhibited nearly similar conversion irrespective of their difference in acidity and all of them showed more than 80% conversion either at 80 or 100 C Hence It is evident that the difference in acidity is not so Important in differentiating the activity of the catalysts The large pore size and hydrophilic and hydrophobic properties are suggested to be the main factors that control acetalization (C) 2010 Elsevier BV All rights reserved
