Abstract: The present invention relates to a liquid lignin mixture comprising 3-50 wt% methanol, 12-50 wt% ligninand5-85 wt% aqueous alkali solution wherein the concentration of said aqueous alkali solution is 1 to 50 wt% of alkali in water, based on the weight of said alkali solution prior to mixing with the other components of the mixture. The liquid lignin mixture can be used to manufacture lignin-based phenolic resins, which are particularly useful in the manufacture of laminates.

Abstract: The present invention relates to a process for preparing a bonding resin, wherein lignin is provided in the form of an aqueous solution and mixed with one or more of a crosslinker and optionally one or more additives. The bonding resin is useful for example in the manufacture of laminates, mineral wool insulation and wood products such as plywood, oriented strandboard (OSB), laminated veneer lumber (LVL), medium density fiberboards (MDF), high density fiberboards (HDF), parquet flooring, curved plywood, veneered particleboards, veneered MDF or particle boards.

Abstract: The present invention relates to a process for lignin dissolution in which partial methylolation of lignin is carried out during the step of preparing a solution of lignin in an aqueous medium comprising alkali and phenol. The lignin prepared according to the process of the present invention can be used to manufacture lignin-based phenolic resins, which are particularly useful in the manufacture of laminates.
