Abstract:
Processes for manufacturing novolacs and resoles from lignin are disclosed. A phenol-aldehyde-lignin dispersion is formed which can then be used to make either a novolac or a resole, depending upon the catalysts used.

Claim (Index 1):
A process comprising:\n a) heating a mixture of a first phenol, lignin, and a first catalyst comprising an acidic compound or a basic compound to a temperature in the range of from 100\u00b0 C. to 200\u00b0 C. to form a dispersion; b) cooling the dispersion to a temperature in the range of 60\u00b0 C. to 99\u00b0 C.; c) adding an aldehyde to the dispersion; d) condensing the dispersion to form a phenol-aldehyde-lignin dispersion having from 1 to 10 weight percent of free aldehyde; e) cooling the phenol-aldehyde-lignin dispersion; f) adding a second phenol to the phenol-aldehyde-lignin dispersion; g) condensing the phenol-aldehyde-lignin dispersion under reflux conditions in the presence of a second catalyst comprising an acidic compound to form a novolac having from 0.01 to 1 weight percent free aldehyde; and h) vacuum distilling the novolac to produce a vacuum distilled novolac having from 0.01 to 10 weight percent free phenol.
