Study of Ln_2O_3/X-13 Sieve as Catalyst for Esterification AITranslate
Abstract AITranslate
Ln2O3/X-13 sieve sorption (Ln= Nd,Sm,Tm,Lu, Dy ),prepared by immersioncalcination method,with 0.83% ~0. 93% RE oxides, has been proved to be quite effective as catalyst for esterification of aromatic phthalic acid or aliphatic acid with primary 2-ethylhexyl alcohol. For example. the conversion percentage of catalyst-bearing DOP is ~10% and 8% higher than that of catalyst-free DOP and X-13. And the conversion percentage of catalystbearing lOP is ~7% and ~4 % higher respectively than that of catalyst-free lOP and X-13. Furthermore, Ln2O3/X-13 sieve sorption contains ~25% less rare earth than Ln2O3/Al2O3 type esterification catalyst and esterification temperature is ~ 10℃ lower. It can be seen from the above that Ln2O3/X-13 sieve sorption is a very good esterification catalyst.
