BIOMASS-DERIVED METHYL METHACRYLATE AND CORRESPONDING MANUFACTURING METHOD, USES AND POLYMERS |
摘要 |
The invention relates to methyl methacrylate characterized in that at least one portion of the carbons thereof is biologically sourced and, more specifically, in that it contains between 0.2×10−10 and 1.2×10−10 wt.-% of 14C in relation to total carbon weight according to the ASTM D6866 standard. The preparation method comprises the use of acetone cyanohydrin as a raw material, said acetone cyanohydrin being obtained by condensing cyanohydric acid on acetone, and the methyl methacrylate is prepared using a process involving the addition of methanol. According to the invention, at least one from among the acetone, cyanohydric acid and methanol is obtained by means of a reaction or series of reactions involving the biomass. |
