Chemical modification of castor oil fatty acids (

Plants oils have been increasingly gaining acceptance in world markets, due to their great potential as raw material to replace conventional mineral oils for formulation of lubricants. In this study, samples of new potential bio-based lubricant molecules were synthesized from castor oil fatty acids....

In this study, samples of new potential bio-based lubricant molecules were synthesized from castor oil fatty acids. The synthesis occurred in three steps: esterification with 2-ethyl-1-hexanol, epoxidation and opening of oxirane rings with different nucleophilic agents: 1-butanol (BIOBUT) and water (BIOWAT). The main objective was to study the influence of hydroxyl groups and branching level on physicochemical properties and thermal degradation of samples. The products obtained in each step were characterized by 1H NMR and their physicochemical properties. The results indicated that the less polar samples (BIOBUT) exhibited a better low-temperature performance (PP −48 °C). Furthermore, BIOBUT has superior oxidation stability (IP 4.22 h) compared to BIOWAT (IP 3.27 h). However, the BIOWAT showed a higher viscosity values (> 470 mm2/s at 40 °C). Thermogravimetric analyses have indicated that BIOWAT shows better thermal stability. Finally, the activation energy determined for the first thermal event for BIOWAT (151 kJ.mol−1) was higher than BIOBUT.

In this study, samples of new potential bio-based lubricant molecules were synthesized from castor oil fatty acids. The synthesis occurred in three steps: esterification with 2-ethyl-1-hexanol, epoxidation and opening of oxirane rings with different nucleophilic agents: 1-butanol (BIOBUT) and water (BIOWAT). The main objective was to study the influence of hydroxyl groups and branching level on physicochemical properties and thermal degradation of samples. The products obtained in each step were characterized by 1H NMR and their physicochemical properties. The results indicated that the less polar samples (BIOBUT) exhibited a better low-temperature performance (PP −48 °C). Furthermore, BIOBUT has superior oxidation stability (IP 4.22 h) compared to BIOWAT (IP 3.27 h). However, the BIOWAT showed a higher viscosity values (> 470 mm2/s at 40 °C). Thermogravimetric analyses have indicated that BIOWAT shows better thermal stability. Finally, the activation energy determined for the first thermal event for BIOWAT (151 kJ.mol−1) was higher than BIOBUT.

abstract	Plants oils have been increasingly gaining acceptance in world markets, due to their great potential as raw material to replace conventional mineral oils for formulation of lubricants. In this study, samples of new potential bio-based lubricant molecules were synthesized from castor oil fatty acids. The synthesis occurred in three steps: esterification with 2-ethyl-1-hexanol, epoxidation and opening of oxirane rings with different nucleophilic agents: 1-butanol (BIOBUT) and water (BIOWAT). The main objective was to study the influence of hydroxyl groups and branching level on physicochemical properties and thermal degradation of samples. The products obtained in each step were characterized by 1H NMR and their physicochemical properties. The results indicated that the less polar samples (BIOBUT) exhibited a better low-temperature performance (PP −48 °C). Furthermore, BIOBUT has superior oxidation stability (IP 4.22 h) compared to BIOWAT (IP 3.27 h). However, the BIOWAT showed a higher viscosity values (> 470 mm2/s at 40 °C). Thermogravimetric analyses have indicated that BIOWAT shows better thermal stability. Finally, the activation energy determined for the first thermal event for BIOWAT (151 kJ.mol−1) was higher than BIOBUT.
