The purpose of using the antirust grease is not only inhibited rust but also reduced mechanical friction. For applying antirust grease onto chains, heating is a common process, but the antirust grease degradation is always occurring during the manufacturing process. This process decreases the properties of lubrication and antirust. The damage proportion, protection ability, and life cycle for chains are influenced without measuring and changing timely. In this study, the antirust grease degradation is affected by operating temperature and operating time. Therefore, a simple and quick electrochemical sensor is expected for quality and degradation detection. This study can be divided into three parts. First, FT-IR has been used to analysis the function group changes of antirust grease after heating. The observation through the adhesion capacity of oil viscosity. Second, the degradation proportion of antirust grease was detected by electrochemical methods. The different proportion of micro to nano sized catalyst was modified onto glassy carbon electrode for this research. Third, the waste grease conversion is carried out to fuel material. This process can achieve the goal of resources recycling. The DPV result shows that the glassy carbon electrode which is modified with 75 % Cu2O/carbon ink/SPEEK to have a good result. During usage time of antirust grease increase, the oxide peaks of DPV decreased at 0 v. FTIR results confirmed that acid catalysis and SrO catalyst can be transesterification successfully. The antirust grease transesterification was catalyzed by 0.05 g SrO and 0.05 ml 5 % H2SO4 had a peak of esters group at 1750 cm-1.
