    摘要:
    在传统的从水介质中通过再结晶纯化粗甲基丙烯酰胺的过程中,控制水溶性甲基丙烯酰胺溶液的pH值至少在碱性范围内的8以上,然后结晶出甲基丙烯酰胺。作为用于pH控制的碱,已经使用了碱金属和碱土金属的碳酸盐和氢氧化物。待再结晶的甲基丙烯酰胺是通过在水的存在下用氨中和丙酮氰水合物和硫酸中和得到的甲基丙烯酰胺硫酸盐得到的粗甲基丙烯酰胺。

    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 14 C 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.
