Dissolution and regeneration of lignocellulosic materials with ionic liquids BMIMCl and ([BMIM] [MeSO4]) and determination some of mechanical and physical properties
In this study two imidazole-based Ionic liquids, 1- butyl -3 - methyl -1 - Imidazolium chloride (BMIMCl) and 1- butyl -3 - Methyl Imidazolium Methyl sulfate ([BMIM][MeSo4]), were used to dissolve wood flour, cellulose and CMP pulp. The overall evaluation indicates the inability of ([BMIM][MeSo4]) in...

| description | In this study two imidazole-based Ionic liquids, 1- butyl -3 - methyl -1 - Imidazolium
chloride (BMIMCl) and 1- butyl -3 - Methyl Imidazolium Methyl sulfate
([BMIM][MeSo4]), were used to dissolve wood flour, cellulose and CMP pulp. The
overall evaluation indicates the inability of ([BMIM][MeSo4]) in full dissolution of
lignocellulosic materials and sample treatment with this solvent was lead to water
soluble degradation products. However, dissolution trials using BMIMCl was able to
dissolve Lignocellulosics. Density, clarity, water absorption and thickness swelling of
regenerated cellulose films were significantly higher than that of CMP and wood
flour, and CMP, higher than wood flour. Also, cellulose film have the lowest water
vapor permeability compared to wood flour and CMP. Tensile strength, Young's
modulus and strain at breaking point of cellulose film were significantly higher than
the CMP and wood flour samples. |
