Catalysis of Organic..

384 Polyurethane from Natural OilThe reactor was purged with nitrogen and heated to 50 ºC under 20 torr vacuum.The vacuum was broken and 500 ppm of stannous octoate catalyst obtained fromCity Chemical was added. The methanol was stripped under 20 torr vacuum at 195ºC for 4-6 hours yielding a viscous light yellow natural oil polyol with an equivalentweight of 660.Polyurethane foam: Natural oil polyol, water, and surfactants were weighedinto a 1 quart metal cup and premixed for 15 seconds at 1800 rpm using a pin typemixer. The catalyst was added and the mixture stirred an additional 15 seconds at1800 rpm. The polyisocyanate was then added and the mixture stirred at 2400 rpmfor 3 seconds and immediately transferred to a 15” x 15” x 10” wooden box linedwith a polyethylene bag. The buns were allowed to cure overnight before testing.References1. List of leading references: a) J. John, M. Bhattacharya, R. Turner, J. Appl.Polym. Sci., 86, 3097 (2002). b) L. Mahlum, US Pat.
