Latest Patents

One of Jetten's latest patents is focused on the recovery of caprolactam from caprolactam-containing distillation residue. This process involves distilling the residue under reduced pressure to obtain a caprolactam-containing distillate. The distillate is then hydrogenated in an aqueous medium to produce a hydrogenation product, from which caprolactam is recovered. Another significant patent is for the purification of 2-pyrrolidone. In this process, impure liquid pyrrolidone obtained from succinonitrile is treated with a strong base and fractionally distilled to yield polymerization-grade purified 2-pyrrolidone. The residue from this distillation is mixed with water and an acid to extract purified 2-pyrrolidone, which can be recycled for further synthesis.
