The present invention can involve a method of synthesizing α-amino-ε-caprolactam. The method can comprise heating a salt of L-lysine in a solvent comprising an alcohol under Super Critical Fluid conditions. The methods can comprise heating a salt of L-lysine in a solvent comprising an alcohol and deaminating the reaction product. In various embodiments, the invention can include methods of converting biomass into nylon 6. The methods can comprise heating L-lysine in a solvent comprising an alcohol to produce α-amino-ε-caprolactam, deaminating to produce ε-caprolactam and polymerizing into nylon 6, wherein the L-lysine is derived from biomass. In other embodiments, the present invention can include methods of making nylon 6. The methods can comprise synthesizing ε-caprolactam and then polymerizing, wherein the ε-caprolactam is derived from L-lysine.
