Supported liquid membranes show great potential in the efficient separation of Me linolenate from its analogs, but there still remain some critical challenges to further this technol. towards larger application because of the slow transmembrane transport and poor stability of liquid membrane. Herein, 1,2-butanediol (1,2-BDO) with good solubility for AgBF4 substitutes for ionic liquid as membrane solvent, and fabric reinforced hollow fiber composite membrane (PR-HFM) with higher mech. strength and interfacial area replaces plate membrane as base support. A new supported liquid membrane has been prepared by coating the 1,2-BDO solution dissolving AgBF4 on the surface of PR-HFM and embedding the solution into the micro-pores of PR-HFM by repeated pull with vacuum and push with N2. The as-prepared liquid membranes exhibit good separation performance and stability. It can be safely and steadily used to treat the feed with fatty acid Me esters (FAMEs) concentration < 150 mg/mL at the velocity of less than 0.22 m/s. Within 24 h continuous operation, Me linolenate (C18-3) can pass steadily through the liquid membrane at the mean permeability > 3.13 x 10-7 m/s, the C18-3 product with the purity > 82%, and the selectivity of C18-3 over C18-2 (SC18-3/C18-2) > 6.63 can be obtained steadily.
Journal of Membrane Science published new progress about Coating materials. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, SDS of cas: 112-63-0.
