Abstract Petroleum oil pesticides are effective acaricides, insecticides, and herbicides, finding application through foliar and leafless woody plant treatments. However, double or triple carbon-carbon bonds in these oils can induce phytotoxic effects, resulting in leaf burn or injury. Consequently, the identification of unsaturated petroleum oils holds significant importance. Traditional approaches for unsaturation detection, such as ASTM D483 Test Method for Unsulfonated Residue of Petroleum Plant Spray Oils and MT (57) Unsulfonated Residue (UR) of natural oil, rely on the utilization of 98% sulfuric acid reagent. This study introduces innovative optical spectroscopic techniques employing Fourier-transform infrared (FTIR) and Raman Spectroscopy to discern between saturated and unsaturated technical petroleum oil pesticides. Three distinct technical petroleum oil samples sourced from different companies in Egypt (El-Mostakble for Chemicals Co. (S1), Kafr El-Zayate for Pesticides and Chemicals (KZ) (S2), and Misr Petroleum Refining Co (S3)) were subjected to analysis. |
