Abstract
A method for determination of vinyl benzoate in ester exchange reaction between vinyl acetate and benzoic acid was studied. With ethylene glycol monobutyl ether acetate as internal standard, Gas chro-matographic analysis was made by using FFAP capillary column and programming temperature. The results showed that good separation effect was obtained. The linearity was good for vinyl benzoate. The linear equation was y=6. 01l 6x + 0. 103 6 and the linear correlation coefficient was 0. 995 9. The relative standard deviation was 0. 66% and the average recovery ranged between 98. 99% -101. 30%. The analysis method provd simple, accurate and reproduible.关键词
