DRYING PROPERTIES OF METATHESIZED SOYBEAN OIL

Soybean oil was metathesized with the standard homogenous metathesis c atalyst, which consisted of tungsten hexachloride (WCl6) and tetrameth yl tin (Me4Sn) in chlorobenzene as solvent. The reactions were termina ted at different time intervals. Soybean ail was mixed with metathesiz ed soybean oil in the presence of cobalt-drier to evaluate drying prop erties. 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 Ga rdner-Holdt viscosity of Z(1)-Z(2) and Z(3)-Z(4) were 71 and 75 min, r espectively. 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.
