MMA is produced by the method of acetone-cyanhydrin mainly in our country. The synthetic route is complex, the technical line is long, and the yield is low with high cost after many steps. Hydrocyanic acid is used as raw material, the treatment of numerous waste acid is difficult . Furthermore, concentrated sulfuric acid consumed in this method corrodes equipments and pollutes the environment seriously.

我国MMA的生产以丙酮腈醇法占主导地位，合成路线复杂，生产工艺长，多步反应后产率低，成本高，其采用有剧毒的氢氰酸为原料，产生大量难于处理的废酸，所消耗的浓硫酸对设备腐蚀性大，对环境污染严重，因此开发新的MMA工艺路线很有必要。

There is a growing need in sulphuric acid plants to increase capacity of existing mist eliminator instal- lations without significant vessel modifications for minimizing overall cost.

越来越多的硫酸装置要求在不过多改动壳体的情况下提高除雾器的处理能力，以降低总费用。

Add 0.1% Dimethyl Sulfate to cell suspensions to methylate free G residues.

调整浓度后的细胞悬液中加入0.1％的硫酸二甲酯(DimethylSulsate，DMS)，进行甲基化处理。

After removing the catalyzer by dense muriatic acid, carbon nanotubes are reacted with mix acid (vitriol:nitric acid=3:1 vol./vol.). By comparing the surface image of gained carbon nanotubes under the different condition, the best mix acid oxidation temperature is fixed on 140°C and the reaction time is 30min. The soluble carbon nanotubes were prepared by decorating of octadecylamine on the surface of nanotubes. Three processes of grafting were investigated in this research.
