“…Currently, synthetics account for up to 10% of the total global production of oils used. In some specific areas of application, ester oils have proven to be in a great demand. − They are required as components for metal working, and dielectric and hydraulic fluids. Nontoxic and biodegradable ester oils are commonly used in the textile and food industries.…”

A new two-stage process is elaborated to produce ester oils with dialkyl carbonate structure which show a very good characteristic in view of their use as lubricants. Di-2-ethylhexyl carbonate and di-3,5,5-trimethylhexyl carbonate were synthesized by transesterification of dimethyl carbonate with 2-ethylhexanol and 3,5,5-trimethylhexanol, respectively. Some oxides, hydroxides, and methoxides of sodium, magnesium, calcium, barium, and aluminum were studied as catalysts for this reaction. Calcium methoxide appeared to be the most suitable, due to its high activity and ease of separation from the reaction mixture. The reaction conditions were mild. The synthesis was carried out under atmospheric pressure at temperatures not higher than 120 °C reaching a relatively high yield of 65−70%. The synthesized oils were characterized by high purity (above 98%) and excellent physicochemical properties. They show a low pour point, a good miscibility with hydrocarbon oils, and a high thermal-oxidative stability.

The lubrication performance of adsorbed triblock copolymers polypropylene oxide‐polyethylene oxide‐polypropylene oxide (PPO–PEO–PPO) with phosphate ester films at different temperature on the Si surface was investigated using a pin‐on‐disc tribometer. The results revealed that the molecular architecture of the triblock copolymer and the temperature had a significant influence on the tribological behaviour. The triblock copolymer with a higher weight percentage of PPO exhibited a better lubrication performance both below and above the cloud point. However, when the temperature is above the cloud point, the adsorbed PPO–PEO–PPO film showed worse lubricity than that below the cloud point. The addition of phosphate ester to the triblock copolymer solution resulted in the decrease of the coefficient of friction and the improvement of the anti‐wear property. Moreover, with the added phosphate ester, the tribological performance became insensitive to the temperature.
