Disclosed in the present invention is the use of a subgroup VI element to prepare a catalyst for the production of organic chemicals from lignin with the involvement of solvent molecules. The catalytic reaction use a catalyst composed of a molybdenum or tungsten compound as the active phase, with mixing a kind of lignin, a catalyst, and a reactive solvent. An inert or reductive gas such as H2, N2 or Ar is used to purge or fill the reaction vessel. The temperature is above 200 °C, the reaction time is sufficient. The liquid product is separated and analyzed. The present invention describes a catalytic process with a very high product yield, up to 90% if calculated accounting the parts from lignin of the product molecules, or up to over 100% if calculated as the mass products. The product includes aromatic compounds, esters, alcohols, monophenols and benzyl alcohols in different ratios according to the catalyst composition, the solvent and the other reaction conditions.
