Optimization of Preparing Conditions of Oil in Water Natural Rosin Emulsion by Response Surface Method
摘要
Abstract
Oil in water(O/W)natural rosin emulsion was prepared by the method of normal pressure phase inversion emulsification with natural rosin as raw material and ONIST APS-350 as emulsifter.The influences of emulsifier dosage, initial emulsification temperature,oil-water ratio(the mass ratio of rosin and water)and stirring speed on the particle size distribution of O/W natural rosin emulsion were investigated,and then the response surface method(RSM)was used to simulate and optimize the process parameters.The results showed that the optimum parameters were determined as follows: stirring speed 500 r/min, emulsifier dosage 9.95%,temperature 112℃, and oil-water ratio 10:31.Under these conditions, the average particle size of emulsion was 131.1nm,the emulsion was not stratified by centrifugal force and not stratified for 3 months.The results of TEM showed that the particles had core-shell structure,and the particle size was consistent with the experimental value.关键词
