Abstract: A new class of oleochemical based polyol esters of general formula 1 are prepared by esterification of different polyols having 5-6 carbon atoms and 2-4 hydroxyl groups with 10-undecenoic acid or/and undecanoic acid with a hydroxyl value of ?1.0 mg KOH/g. Wherein R1, R2, R3 is selected from a group consisting of CH3—, CH3CH2—, —CH2OCOR4 wherein R4 is selected from CH2?CH—(CH2)8— or CH3—(CH2)9—, individually or in combination thereof. The resulting esters were characterized for lubricant properties like viscosity, viscosity index, pour point, flash point and copper corrosion tests. The properties indicate their potential as promising lubricant base stocks for automotive lubricants, metal working oil, hydraulic oil and other industrial applications. Vegetable oils provide most of the desirable lubricant properties such as good boundary lubrication, high viscosity index, high flash point and low volatility.

Abstract: 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 anti foaming agent, a pour point depressant, a corrosion inhibitor and a detergent-dispersant additive. The product of this invention has utility as industrial and automotive gear oil GL 4 grade. The compositions are significantly biodegradable, eco-friendly, reduce use of petroleum, have lower cost than synthetic oil, are miscible in mineral & synthetic fluids and safe to use due to higher flash point.

Abstract: The present invention discloses an improved process for the production of desired recombinant peptides from bacterial cells by using G-CSF as a novel fusion partner for their high level expression in these cells. The invention further provides an expression system comprising the fusion protein wherein the G-CSF is operatively linked to the peptide of interest via an enzymatic or chemical cleavage site which can be used to separate the fusion partner from the said peptide.
