Lubricant basestocks from vegetable oils
Oil Chemical Research. USDA l-ARS-NCAUR. 1815 N. U;liuersity Street, Peoria, IL 61604, USA Accepted 8 October 1999 Compared to the lubricants made of petroleum, vegetable-based lubricants are much more biodegradable but inferior in many other technical characteristics. The basestock typically contributes to more than 80% of lubricant and must meet performance criteria in such aspects as cleanli...
متن کاملReactive Applications of Cyclic Alkylene Carbonates
The synthesis and use of cyclic alkylene carbonates as reactive intermediates first appeared in the literature more than 50 years ago. However, the range of their usefulness in industrial applications has only been fully realized in the past decade. In this article, numerous reactive applications of the cyclic alkylene carbonates, specifically the five-membered cyclics, are discussed. In additi...
متن کاملConvenient preparation of fatty ester cyclic carbonates
The cyclic carbonate moiety finds many industrial applications because of its unique chemistry and properties. Phosgene, a highly toxic and corrosive reagent, has been utilized in the past to prepare low yields of fatty ester compounds (1) that contain a five-membered cyclic carbonate group. Herein, we show (CH3)4N HCO3, tetramethylammonium hydrogen carbonate (TMAHC), to react efficiently with ...
متن کاملAn Investigation on Vegetable Oils as Potential Insulating Liquid
While choosing insulating oil, characteristic features such as thermal cooling, endurance, efficiency and being environment-friendly should be considered. Mineral oils are referred as petroleum-based oil. In this study, vegetable oils investigated as an alternative insulating liquid to mineral oil. Dissipation factor, breakdown voltage, relative dielectric constant and resistivity changes with ...
متن کاملVegetable oils as protectants against nematode infections.
In this experiment, 0, 0.125, 0.25, 0.5, and 1.0 ml of each oil dissolved in 1 ml of 95 % ethanol was added to 1 kg of soil containing 370 P. penetrans per kg, and incorporated by shaking. After 10 days at 22 ± 3 C, a four-week-old tomato (Lycopersicon esculentum Mill cv. Bonny Best) seedling was planted in each of six 5-cm-diam plastic pots containing 100 g of treated or untreated infested soi...
