Title
Basic ionic liquid immobilized oxides as heterogeneous catalyst for biodiesel synthesis from waste cooking oil
Abstract

•The functionalized basic ionic liquid [Bmim]OH was synthesized.•IL could be grafted onto oxides surface by immobilization for transesterification.•The FAME yield catalyzed by IL/Mg-Al-La was 98.7% at 338 K in 6 h.•IL immobilized oxides exhibited high activity as heterogeneous catalyst.•IL/Mg-Al-La catalyst exhibited accepted activity after 6 recycles.

The basic ionic liquid (IL) [Bmin]OH was synthesized and immobilized onto oxide surface to obtain IL/Mg-Al and IL/Mg-Al-La catalysts. The catalysts were characterized by FT-IR, XRD, EDS, BET and basic test. The results proved that the IL immobilized oxides exhibited high activity for biodiesel synthesis from waste cooking oil. The high FAME yield of 98.7% could be obtained at 338 K, 12:1 methanol to oil, 3 wt% catalyst amount and 6 h reaction time by IL/Mg-Al-La catalysts.
