The ionic liquid was used four times without any dramatic decrease in ester yield. And the methyl ester was checked by 1H NMR. © 2014 Trans Tech Publications, Switzerland. publisher: Trans Tech Publications Ltd date: 2014 type: Article type: PeerReviewed identifier: Ullah, Z. and Bustam, M.A. and Man, Z.
