An article from the UMU, published in the leading journal of Green Chemistry (25/01/2017)

An article by researchers at the University of Murcia (UMU), led by the Dean of the Faculty of Chemistry, Pedro Lozano, is the cover of the January issue of Green Chemistry magazine, edited by the Royal Society of Chemistry and leading publication World level in the field of Sustainable Chemistry.

In this study, the UMU research team presents a new method for the selective synthesis and subsequent separation of monoglycerides (substances of high added value for the cosmetic and food industry) through green processes based on the use of enzymes and ionic liquids Sponge type.

The latter are a new type of solvents that never evaporate, which allows their total recovery for later reuse and thus determines the sustainability of their possible applications.

In addition to this selective synthesis procedure based on the enzymatic esterification between glycerine (by-product of the biodiesel industry) and free fatty acids, the article describes for the first time a direct method of separation of various monoglycerides, such as monolaurin and Monoolein, with yields of 100% in the pure product.

This is achieved thanks to the properties of these new sponge-type ionic liquids and the use of simple laboratory techniques that are directly implementable to industrial processes.

The integral recovery and reuse of the enzymes and sponge-type ionic liquids used in the described process is demonstrated in the article, whose selection for the cover of Green Chemistry is a reflection of the scientific development of the UMU in a thematic area of ​​the impact and competitiveness of the Green / Sustainable Chemistry.
