Environment-friendly ethylene glycol di-esters (EGDEs) as, biolubricants were produced from different vegetable oils by applying CaO as a heterogeneous base catalyst through transesterification of fatty acid methyl esters (FAMEs) and ethylene glycol (EG). The feedstocks used were sunflower, soybean, jatropha, and waste cooking oils. The molar ratio of FAMEs to EG was 2:1, catalyst dose (1.2% w/w), and temperature 150 degrees C for 2 h reaction time; under vacuum were the transesterification conditions. The produced biolubricants were identified using FTIR technique. The thermal stability of each produced biolubricants was examined using TGA technique. The viscosity indexes of the produced EGDEs were calculated and their values exceeded 140 for waste oil to 311 for Jatropha oil. The rheology characteristics, that define the nature of the produced biolubricants, were determined. This study proved that the production of different biolubricants having suitable chemical and rheological properties fitted to be used as commercialized industrial lubricants.
