TRUJILLO-VERA, Diego Alejandro  and  VELEZ-SALAZAR, Yesid. Study of different routes of renewable synthesis for Caprolactam production. Dyna rev.fac.nac.minas [online]. 2018, vol.85, n.204, pp.231-237. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v85n204.67549.

There are not methods for direct biobased synthesis of caprolactam (CPL), the combination of biotechnological production of renewable raw materials with physical and chemical modifications are emerging and showing promising results. Among these raw materials there are some acids: adipic, glucaric, glutamic, levulinic, succinic, muconic, 2,5-furanicarboxylic, 6-aminocaproic; and other compounds: adiponitrile, lysine, 1,3-butadiene, 1,4-butanediol, Hydroxymethylfurfural, adipic semialdehyde, benzene, phenol and ethanol. There are barriers that have not allowed the viability and commercial development of these processes, such as limitations on the fractionation of lignocellulosic biomass, high-energy requirements for separation of products, low yield, biological inhibition, limited chemical selectivity and low purity of products. Research and development efforts of any of these processes were not identified in Colombia. The route through the lysine is the most promising by involving few reaction stages, by having economic raw materials and because it is carried out under moderate operating conditions.

Keywords : caprolactama; nylon 6; lysine; adipic acid.
