摘要

Abstract

Preparation of biodiesel from waste oils containing 72% of free fatty acids catalyzed by a novel Brønsted acidic ionic liquid 1-sulfobutyl-3-methylimidazolium hydrosulfate ([BHSO

MIM

]

[HSO

]

) was systematically investigated. The optimum molar ratio of methanol to waste oils

catalyst amount

reaction temperature and reaction time were 8/1

10% (based on the mass of waste oils)

140℃ and 6 h

respectively

under which the obtained yield of biodiesel reached 94.9%. Also

[BHSO

MIM

]

[HSO

]

as a catalyst still retained around 97% of its original catalytic activity after successive re-use of 5 batches (6 h per batch)

showing the excellent operational stability. Moreover

the acidic IL[BHSO

MIM

]

[HSO

]

was able to efficiently catalyze conversions of waste oils with different amounts of FFAs (free fatty acids) into biodiesel

and showed tremendous application potential. Therefore

an efficient and environmentally friendly catalyst is provided for the synthesis of biodiesel from waste oils with high acid value.
