The present invention provides a process for producing novel lignin derivatives, which comprises using a lignophenol derivative containing a diphenylpropane unit formed by binding a carbon atom at an ortho-position relative to a phenolic hydroxyl group of a phenol derivative to a carbon atom at a benzyl-position of a phenylpropane fundamental unit of lignin, and binding an oxygen atom of the hydroxyl group and a .beta. -positional carbon atom under alkali conditions under which the hydroxyl group can dissociate, to obtain an arylcoumaran derivative containing an arylcoumaran unit in which a coumaran skeleton is bound to an aromatic ring of lignin.
La présente invention porte sur un processus de production de nouveaux dérivés de lignine qui consiste à utiliser un dérivé de lignophénol contenant une unité de diphénylpropane que l'on forme en alliant un atome de carbone en position ortho par rapport au groupe hydroxyle phénolique d'un dérivé phénolé à un atome de carbone en position benzylique d'une unité fondamentale de phénylpropane de la lignine, et en alliant un atome d'oxygène du groupe hydroxyle à un atome de carbone en position bêta dans des conditions alcalines dans lesquelles le groupe hydroxyle peut se dissocier pour obtenir un dérivé d'arylcoumarine contenant une unité d'arylcoumarine dans laquelle un squelette de coumarine est lié à un noyau aromatique de lignine.
