Abstract
A soybean oil based hydraulic fluid of which the soybean oil is less than 85% by weight and the fatty acid profile of the hydraulic fluid includes about 0.12% C24:0. The base oil is hydrogenated to produce maximum possible stability of the soybean oil, and is winterized to remove crystallized fats and improve the pour point of the base oil without the necessity of heating the oil. The base oil is then combined with a hydrocarbon based additive package containing materials specifically designed for mobile equipment application including friction and anti-chatter materials, needed for wet clutches and brakes.
Claims10
A process for producing a soybean-based hydraulic fluid comprising:
- partially hydrogenizing crude soybean oil to stabilize the oil;
- winterizing the stabilized soybean oil to remove crystallized fats;
- and combining the soybean oil with a chemical lubricant additive to produce a hydraulic fluid having a kinematic viscosity in the range of 40-51 cSt @ 40.degree. C.
The process of claim for producing a soybean oil based hydraulic fluid in which the soybean oil is less than 85% by weight.
