摘要
Delignification of biomass consisting of lignin containing plant is done by utilizing an amino compound in and aqueous solution at ambient temperature up to 150 degree C. to produce and aqueous solution of amino salt of lignin and an amino-lignin-cellulose which is not soluble in water. The aqueous solution of amino salt of lignin is then filtered off of the amino-lignin-cellulose. The aqueous solution of amino salt of lignin or the amino salt of lignin with the amino-lignin-cellulose may be reacted with an aldehyde to produce an amino-lignin-aldehyde resin or an amino-lignin-cellulose aldehyde resin which may be of the thermoplastic or thermosetting type. The thermoplastic resins are fire resistant, hard, strong, not water soluble and may be used to make exterior fiberboard, OAS boards, plywood, molded products, etc. These urea salts of lignin may also be utilized as long acting fertilizer, to produce plastics and other products.;The amino-lignin-cellulose may be hydrolyzed by any suitable means such as acid hydrolysis into carbohydrates which can be fermented in alcohol.
