Green Chemistry: Rapid Quantitative Analytical Tool for Characterizing the Preparation of Biodiesel

A brand new qualitative method of producing biodiesel has been introduced. “The use of 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane as a phosphitylation reagent for quantitative P NMR analysis of the hydroxyl groups in biodiesel process samples has been fully developed” (Nagy A). This test protocol gives opportunity for quick analysis of biodiesel composites of alcohols, glycerol, aliphatic acids, and mono- and 1,2-disubstituted glycerides. Distinctive chemical shift limits were developed “with model compounds and used to fully characterize the conversion of triglyceride samples to biodiesel for two commercial production processes” (Nagy A).

During the experimental section effects of nuclear magnetic resonance (NMR) and 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane (TMDP) were applied to biodiesel. Obtained results showed that this NMR/TMDP technique is a “promising research tool for the biodiesel industry” (Nagy E). This technique covers quantitative information on the concentration of ethanol, free glycerol, partly hydrolyzed triglycerides, and free aliphatic acids in a quick way. As the spectrographic information received by the TMDP/NMR methodology is linked with the structure of used the phosphitylating agents and the compound agents, it gives spectra good separation even if it is a complex sample, becoming a quick and exact quantitative method. Because of optimized sample treatment and signal purchasing “TMDP/NMR method can handle samples through the whole production line regardless of process step or feedstock used, becoming a novel research tool for process step optimization and for the characterization of biodiesel and its processing components” (Nagy E).

Concerning my point of view, these research must be continued as it will provide world with better, more productive fuel.
