Some empirical equations for oxypolymerization of linseed oil

In this study, oxypolymerization of linseed oil was investigated. The reaction was carried out at 80, 120 and 200°C with the airflow of 2 and 5 L/min. Changes in viscosity, density, refractive index, iodine and peroxide values were determined during reaction and some empirical equations were obtained. Additionally, a kinetic investigation was achieved and, the reaction order and the rate constant were determined for each reaction. Change in the reaction order with the temperature could be explained with different reaction mechanism for each temperature. Rheological behavior of the final product was investigated using Bingham, Power-law and Casson equations. It was found that the sample behaved as non-Newtonian fluid at high temperature.
