The invention relates to a method for producing phenols, aldehydes, esters and/or ketones with the utilization of lignin and/or lignin sulphonic acid in which the starting materials containing lignin or the lignin sulphonic acid are heated. The desired substance is evaporated from said starting materials, while acceptable products are produced from the solid components of the starting materials by means of heat action. In addition, the originated boundary conditions which stimulate the desired substance are adhered to. Said boundary conditions are abnormal but innocuous for producing the acceptable products from the solid components of the starting materials.
L'invention concerne un procédé pour produire des phénols, des aldéhydes, des esters et/ou des cétones à l'aide de lignine et/ou d'acide sulfonique de lignine, dans lequel les matériaux de départ contenant la lignine ou l'acide sulfonique de lignine sont chauffés. La substance désirée est évaporée à partir de ces matériaux de départ, tandis que des produits valorisables sont fabriqués à partir des constituants solides des matériaux de départ sous l'action de la chaleur. A cet effet, sont respectées des conditions marginales favorisant la formation de la substance souhaitée, lesquelles sont anormales mais inoffensives pour la fabrication des produits valorisables issus des constituants solides des matériaux de départ.
