Abstract:

Phosphitylation of hydroxyl groups in biodiesel samples with 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane followed by 31P-NMR analysis provides a rapid quantitative analytical technique for the determination of substitution patterns on partially esterified glycerols. The unique 31P-NMR chemical shift data was established with a series mono and di-substituted fatty acid esters of glycerol and then utilized to characterize an industrial sample of partially processed biodiesel.

  • The goal of the creation of a biobased economy is challenging to agriculture, forestry, academia, government and industry. The extractable resources of the Earth are finite, regardless of the quibble over when they will be depleted. The economic, political and social demands for biobased chemicals, materials and energy are expected to radically transform the materials industries, particularly the plastics industry as well as the biofuel industry. These changes will be based on the principles of sustainability, eco-efficiency, industrial ecology, and green chemistry and engineering. In keeping with the growth of knowledge in this field, there is a strong need for a forum to share original research related to biobased materials and bioenergy. The Journal of Biobased Materials and Bioenergy (JBMB) has been created as an international peer-reviewed periodical to fulfill the need for communication in these research areas. This journal will encompass related research activities in all fields of science, engineering and the life sciences.
