Microcrystalline cellulose (MCC) was treated by two kinds of ionic liquids (ILs), 1-n-butyl-3-methylimidazolium chloride ([Bmim]Cl) and 1-n-allyl-3-methylimidazolium chloride ([Amim]Cl), in order to dissolve the highly crystalline structure and enhance the hydrolysis rate of MCC. MCC's structural changes were determined in detail using FTIR, CP/MAS 13C NMR, XRD and XPS. MCC was found to have undergone characteristic structural changes after interaction with ILs. The rates of acid hydrolysis were found to be around twice as high for MCC treated with ILs as compared to untreated MCC. The treatment with [Bmim]Cl increased the hydrolysis rate more than the treatment with [Amim]Cl.

  • 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.
