Latest Patents

Dellinger's latest patents include groundbreaking processes for reclaiming epsilon-caprolactam from nylon 6 carpet. This process involves continuously recovering epsilon-caprolactam from carpets made from nylon 6 face fibers and backing. The carpet is fed into a separator to prepare scrap containing nylon 6 and auxiliary materials. The scrap is then processed in a depolymerizing reactor to produce an epsilon-caprolactam containing distillate, which is subsequently purified. Additionally, he has developed a method for recovering caprolactam from mixed waste. This process involves agitating waste in an acidic solvent that dissolves polycaprolactam without degrading insoluble materials. The solution is then separated and depolymerized to obtain substantially pure caprolactam.
