L. oil extracted by switchable solvent
Shanjin Zeng, Chuandong Tao, Richard Parnas, 等. Jatropha curcas L. oil extracted by switchable solvent N, N-dimethylcyclohexylamine for biodiesel production[J]. 中国化学工程学报(英文版), 2016,24(11):1640-1646.DOI: 10.1016/j.cjche.2016.04.023.
which is a renewable and environmentally friendly fuel
has been studied widely to help remedy increasing environmental problems. One of the key processes of biodiesel production is oil extraction fromoilseed materials. Switchable solvents can reversibly change from molecular to ionic solvents under atmospheric CO
2
and can be used for oil extraction. N
N-dimethylcyclohexylamine (DMCHA)
a switchable solvent
was used to extract oil from Jatropha curcas L. oil seeds to produce biodiesel. The appropriate extraction conditions were:1:2 ratio of seedmass to DMCHA volume
0.3-1mmparticle size
200 r·min
-1
agitation speed
60min extraction time
and 30℃ extraction temperature. The extraction ratio was about 83%. This solvent extracted the oil more efficiently than hexane
and ismuch less volatile. By bubbling CO
2
under 1 atmand 25℃ for 5 h
the oilwas separated
and DMCHA was recovered after releasing CO
2
by bubbling N
2
under 1 atmand 60℃ for 2 h. The residual solvent content in oil was about 1.7%. Selectivity of DMCHA was evaluated by detecting the protein and sugar content in oil. Using the oil with residual solvent to conduct transesterification process
t
he oil conversion ratio was approximately 99.5%.
