An environmentally friendly lubricating grease composition as well as several processes for preparing the grease composition is desecribed which comprises (A) a base oil wherein the base oil is a natural oil or synthetic triglyceride of the formula ##STR1## wherein R 1,R 2 and R 3 are aliphatic groups that contain from about 7 to about 23 carbon atoms and (B) a thickener wherein the
Patents; Vegetable oil lubricant is biodegradable and said
Their patent covers a vegetable oil lubricant they say is biodegradable as well as more efficient at lubrication and heat transfer than petroleum-based oils. Their lubricant uses three elements: a
Equipment manufacturers who use these lubricants have observed that product performance declines when so-called “biodegradable” based fluids are used. In addition to the environmentally friendly qualities such as biodegradability, recent regulatory initiatives are directed to using fluids derived from renewable resources (e.g., from agricultural products).
US8557754B2 Composition of biodegradable gear oil
A composition of biodegradable gear oil that mainly contains modified nontauedible vegetable oils. Mono-esters are hydrogenated, epoxidized or aryl alkylated or mixture thereof, and C7 to C12 primary alcohol. In addition to chemically modified non-edible vegetable oils, the composition also contains an additive pack, which comprises at least one: antioxidant, an extreme pressure additive, an
Karanja oil: an alternative feedstock for bio-based lubricants. Researchers at the Institute of Science and Technology for Advanced studies and Research (ISTAR), in the State of Gujarat, India, have successfully modified a non traditional vegetable oil, to produce bio-based lubricants. The study was carried out on chemically modify Karanja oil.
US6117827A Biodegradable lubricant base oil and its
A biodegradable lubricant base oil of satisfactory low-temperature fluidity, oxidative stability and lubricity, and having a low cloud point, is disclosed. The lubricant base oil is manufactured by mixing and subjecting the following simultaneously to an ester-interchange reaction in the presence of an enzymatic catalyst: (A) 30 to 60% by weight of a fat/oil containing 20% by weight or more
The invention relates to a biodegradable functional fluid composition based on vegetable oil. This functional fluid suitable for lubricant, hydraulic and like fluid comprises palm olein and its by-product generated from fractionation of palm oil. The by-product is esterified by a hindered alcohol prior to blend together with palm olein and additive packages.
US Patent for Rolling bearing Patent (Patent # 6,517,250
Typical bearing lubes include grease and oil. Rolling bearings are used as machine parts in various industrial machines. When their working life has expired, these machines are usually burned, dumped into the sea, left in unpopulated areas, or buried in the ground without dismounting the bearings.
the industry to find out more variety of biodegradable lubricants. One of the easily available and commercially good biodegradable lubricants is vegetable oils. The total lubricant consumption in Western Europe was 5,020,000 tons/year in 2002, of which 50000 tons per year were based on vegetable oils. In the US around 8,250,000
