Soybean oil was metathesized with the standard homogenous metathesis catalyst, which consisted of tungsten hexachloride (WCl 6 ) and tetramethyl tin (Me 4 Sn) in chlorobenzene as solvent. The reactions were terminated at different time intervals. Soybean oil was mixed with metathesized soybean oil in the presence of cobalt‐drier to evaluate drying properties. Five weight percentage (% w) of metathesized oil was found to be all that was needed to decrease the drying time of soybean oil from 312 to 182 min. Drying times for heat‐polymerized soybean oil with Gardner‐Holdt viscosity of Z 1 –Z 2 and Z 3 –Z 4 were 71 and 75 min, respectively. In both cases, 5% weight metathesized soybean oil in the blend gave the best results for reducing drying time to 67 and 69 min, respectively.
