OPTIMIZING THE ESTERIFICATION PROCESS OF RSO MODIFIED WATER BORNE ALKYD RESIN USING RESPONSE SURFACE METHODOLOGY (RSM)
Publication Date : 15/03/2018
The optimization of esterification process of self-emulsifying method of rubber seed oil (RSO) modified water borne alkyd resin was investigated. Response surface methodology (RSM) analysis using design matrix of FFA linked with CCRD in coded notation for RSO modified water borne alkyd resin synthesis was used to optimize important process parameters comprising the reaction temperature, catalyst ratio, reaction time, oil ratio, viscosity, molecular weight of the resin coupled with their interaction on the oil sample. The optimum conditions (reaction temperature of 260 0C, reaction time of 180 mins, oil ratio of 0.43, catalyst ratio 0.1, stirring rate of 500rpm) were determined by the results of statistical screening analysis under which the experiment was performed. The results obtained revealed that the maximum responses of 89.66% fractional conversion, viscosity of 293.197Cp, average molecular weight of RSO water borne alkyd MW(av) of 5481 were determined based on economic consideration. Hence, the experimental value of 0.89 was in accordance with the predicted modal value of 0.89.
