대표청구항▼
1. A method of making a lignomethylol or a lignosulphonate methylol, the method comprising contacting a lignin or a lignosulphonate with formaldehyde or paraformaldehyde or glyoxal under conditions sufficient to produce the lignomethylol or the lignosulphonate methylol, wherein the lignomethylol has
1. A method of making a lignomethylol or a lignosulphonate methylol, the method comprising contacting a lignin or a lignosulphonate with formaldehyde or paraformaldehyde or glyoxal under conditions sufficient to produce the lignomethylol or the lignosulphonate methylol, wherein the lignomethylol has a formula of: 2. The method of claim 1, further comprising epoxidizing the lignomethylol or the lignosulphonate methylol under basic pH conditions to produce a lignomethylol epoxy or a lignosulphonate methylol epoxy. 3. The method of claim 1, further comprising contacting the lignomethylol or the lignosulphonate methylol with ammonia or an amino compound to produce a water soluble aminolignin derivative. 4. The method of claim 3, wherein the aminolignin derivative has a formula of Formula I, wherein each R1 is independently selected from the group consisting of NH2, —NHCH2CH2NH2, diethylenetriamine, triethylenetetraamine, tetraethylenepentaamine, hydroxylamine, hydrazine, monoethanoloamine, diethanolamine, and triethanolamine. 5. The method of claim 3, wherein the amino compound is a monoethanolamine, a monoalkylamine, dialkylamine, trialkyl amine, ethylene diamine, diethylenetriamine, tetraethylene pentamine, mono ethanol amine, diethanolamine, triethanolamine, isophorone diamine, hydroxylamine, or hydrazine. 6. The method of claim 3, further comprising drying the water soluble aminolignin derivative. 7. The method of claim 3, further comprising contacting the amino lignin with ethanolamine, a hydroxycarboxylic acid salt, a polyhydroxycarboxylic acid, an isocyanate terminated polyalkylene oxide, an epichlorohydrine, a hydroxycarboxylic acid salt, or a polyhydroxylic acid salt to produce a surfactant. 8. The method of claim 3, further comprising contacting the aminolignin with epichlorohydrine at a temperature of about 0-10° C. to produce a ligno aminoepoxy resin. 9. The method of claim 8, wherein the ligno aminoepoxy resin has a formula of: 10. The method of claim 8, further comprising contacting the ligno amino resin with phosgene, carbon monoxide, or carbon dioxide to produce a lignoisocyanate derivatives. 11. The method of claim 1, wherein the method does not comprise a volatile organic compound. 12. A method of curing an ligno amino epoxy resin, the method comprising contacting a ligno aminoepoxyresin with a water soluble aminolignin according to their epoxy equivalent weight for a sufficient time at room temperature until the resin is cured. 13. A composition comprising a compound having a formula of wherein each R1 is independently selected from the group consisting of NH2, NH2CH2CH2NH2, diethylenetriamine, triethylenetetraamine, tetraethylenepentaamine, hydroxylamine, hydrazine, monoethanoloamine, diethanolamine, and triethanolamine. 14. The composition of claim 13, wherein the compound has a formula of 15. The composition of claim 13, wherein the compound has a formula of Formula I, wherein each R1 is independently selected from the group consisting of NH2, NH2CH2CH2NH2, diethylenetriamine, triethylenetetraamine, tetraethylenepentaamine, hydroxylamine, hydrazine, monoethanoloamine, diethanolamine, and triethanolamine. 16. The composition of claim 13, wherein the composition compound has a formula of wherein R1 is independently selected from the group consisting of NH2, NH2CH2CH2NH2, diethylenetriamine, triethylenetetraamine, tetraethylenepentaamine, hydroxylamine, hydrazine, monoethanoloamine, diethanolamine, and triethanolamine. 17. The method of claim 12, wherein the ligno aminoepoxyresin has a formula of:
