“…Based on the best of our knowledge, there is no report about the application of the cited substance in motor oil and hydraulic fluid formulation. In continue of our interest in lubricants (Ashrafi et al, 2013;Semnani and Shakoori Langeroodi, 2013;Shakoori Langeroodi and Semnani, 2013), in this paper we reports the results of combination of HAB with mineral base oils SN-100, SN-150, and SN-650, as well as synthetic base oil PIB.…”

Heavy alkyl benzene (HAB) is a byproduct in the process of linear alkyl benzene (LAB) production. It is used as heat transfer oil and lubricating greases. In this article the potential of the usage of HAB in the formulation of gasoline and diesel engine oils as well as hydraulic fluid is indicated. With the aim of passing 5W30, 5W40, 10W40, and 15W40 standards, different engine oils have been formulated. The formulations contain various amounts of HAB as minor component, and miscellaneous quantities of solvent neutral 100 (SN-100), SN-150, and SN-650 as major component. The measurement of typical properties of obtained oils indicates that some of them do have the intended criteria. Test field of the recent oils designate that they have good performance. In the next step, different blends of HAB as major component and polyisobutene (PIB) as minor component have successfully been employed in the formulation of several ISO grade hydraulic fluids. The achieved materials do have suitable air release and demulsibility.

Solvent neutral 100 (SN-100), SN-150, SN-500, and SN-650 base oils have been investigated by electrochemical impedance spectroscopy (EIS). The investigation has been followed in the frequency range of 100 kHz to 1 mHz. The results indicate that in all cases upon decrease of frequency, the impedance (Z) will be raised up. Also obtained data designates that at each applied frequency, Z values vary in the order: SN-100 < SN-150 < SN-500 < SN-650. In all cases, plots of phase angle versus log of frequency are nearly peak shaped. Based on the composition of base oils, the possible reasons for the different observations has been discussed. The equivalent circuit consists of a parallel constant phase element and polarized resistance (R ct ), in series with solution resistance (R s ). Linear correlation has been observed between R ct and viscosity at 40 or 100 • C, as well as log R ct and viscosity index or specific gravity.

“…In this paper chemical modification by initial epoxidation of sunflower oil, followed by acetylation of epoxidized intermediate has been followed. This research is in continuing of our research on lubricants [24][25][26][27][28][29]. Economic considerations involve chemical modifications to be directed toward catalyst which could be applied at ambient temperature.…”

ABSTRACT. Lubrication properties of sunflower oil have been modified by epoxidation in the first step and acetylation of the obtained epoxide in the second step. Epoxidation has been followed in dichloromethane solution in the presence of hydrogen peroxide and acetic acid as oxidizing agent and sulfuric acid as catalyst. The reaction has been monitored and optimized by measurement of iodine value, epoxy content, and recording the FTIR spectrum at different experimental conditions. Acetylation has been performed by enduring the optimized conditions of epoxidation reaction, in the presence of boron trioxide as catalyst and at elevated temperature. The recent reaction has been monitored and optimized by measurement of hydroxyl value, epoxy content, and recording the FTIR spectrum at different experimental conditions. The final product of both,epoxidation and acetylation reactions has been confirmed by FTIR and NMR data. Relative to sunflower oil, pour point and oxidation stability of the modified oil has considerably been improved. The modified oil has successfully been employed in the formulation of industrial gear oil. The investigation on the possibility of the additive application of the modified oil, as well as its miscibility with additives was considered.
