The diphenyl disulfide (DPDS) effect in monosulfidic and disulfidic crosslinks under microwave heating was investigated. Digeranyl monosulfide and disulfide was synthesized and was tested as models using Reaction Stage Modeling (RSM). Geranyl bromide was slowly added, and the solution was stirred overnight at room temperature. Ethanol was evaporated under reduced pressure. A liquid-liquid extraction with 150 mL water and 50 mL diethyl ether was performed in order to concentrate the NaBr formed during the reaction in the aqueous phase and the desired product in the organic phase. Two different HPLC-UV methods were used to characterize samples. the UV detector was set at 254 nm and the mobile phase was acetonitrile:water, with a flow of 1 mL/min and an injection volume of 2μL. It was observed that RSM in combination with HPLC techniques appear to be an effective tool to study the devulcanization effect on the different crosslink compounds.
