Abstract
The amount oftrans unsaturation in 80 IV hydrogenated soybean oil produced under different reaction conditions of pressure, temperature, catalyst concentration and agitation may be calculated with good accuracy from a polynomial equation. The polynomial equation was developed from data produced by 30 experimental hydrogenations using a nonlinear equation estimation procedure with a digital computer to fit the data. The equation may be used to calculate the anticipated amount oftrans unsaturation from the reaction conditions or select reaction conditions to produce a desired amount oftrans unsaturation.
