Özet:

 Caprolactam is most commonly used in the production of Nylon 6 in industry and is generally produced from cyclohexanone by the Beckmann rearrangement. Orthophosphoric acid is generally used in fertilizer production and is produced through two processes: wet and dry. In this study, detailed characterization of CL-PA was carried out by synthesizing CL-PA ionic liquid from orthophosphoric acid PA and caprolactam CL. FTIR, Raman and UV-Vis spectroscopic analyses reveal that a bond is formed between CL and PA. The thermal behavior of CL-PA ionic liquid was inspected by TGA and DSC. It has been observed that the decomposition temperature of CL-PA ionic liquid is different from that of the starting materials CL and PA. It was disclosed by DSC analysis that CL-PA ionic liquid only has a glass transition temperature. The room-temperature CL-PA ionic liquid synthesized from solid CL with melting point of 70.34  and 85 wt. PA did not show any melting or freezing point and the glass transition temperature was found to be 27 . It was revealed that CL-PA ionic liquid was more thermally stable than CL which alone almost completely evaporated at about 197 . As a result of FTIR analysis of CL-PA ionic liquid and its constituents, it was demonstrated that NH peaks of CL disappeared in the CL-PA spectrum and the peak of CO group shifted to a lower frequency i.e., 1604 cm1. In the Raman analysis of CL-PA and its constituents, it was observed that the asymmetric CO bending vibration and CO stretching vibration of CL disappeared in the CL-PA spectrum. In the UV spectrum, it was observed that the maximum absorbance of CL-PA ionic liquid varied with respect to that of CL.
