摘要

Invention patent: b "process for the production of phenols, aldeu00ecdos, esters and / or ketones from lignin and / or acid sulfu00c8nico lignin" d .Process for the production of phenols, aldehydes, esters and / or ketones from lignin and / or lignin sulphonic acid.In the basic products containing lignin and / or lignin sulphonic acid are heated, from which the desired substance evaporates.The process is characterized by the fact that the base products are heated, while that of the fixed components of the base products are obtained products usable under the effect of heat.It is necessary to the fulfilment of certain conditions for the formation of the desired substance, which, for the production of products usable from the fixed components of basic products,Despite the unusual are harmless.
