| titleOfInvention | Method for preparing phenolic chemicals through thermo-chemical conversion of industrial lignin |
| abstract | The invention provides a method for preparing phenolic chemicals through the thermo-chemical conversion of industrial lignin. The method is as follows: under the common functions of solid acid catalyst and hydrogen supply solvent, industrial lignin performs atmospheric thermo-chemical conversion in high boiling point organic reaction medium to prepare homogeneous low molecular weight organic matter with rich phenolic compounds such as phenol, methoxyphenol, dimethoxyphenol and 2-methoxy-4-methylphenol, and the organic reaction medium is recycled through the technologies such as vacuum distillation. The method has simple process, good stability and low production cost; and the yield of the prepared phenolic compounds is more than 54%. The method plays an important role in the high-valued comprehensive utilization of the renewable resource, namely ndustrial lignin; and the converted phenolic chemicals can be used to synthesize phenolic resin, prepare high efficiency cement water-reducing agent and further separate, purify and prepare bio-chemicals. Particularly, by adopting the method, the lignin in papermaking black liquid and preparation residue of biological fuel ethanol prepared from cellulose can be converted to phenolic chemicals; and the method has wide application prospect. |
