摘要
Abstract
A new type of parallel synthesizer was introduced,and its performance characteristics were described in detail.The hydroxyl value was determined by reactor-parallel synthesizer through acetic anhydride method and phthalic anhydride method.The results were compared with the results obtained by GB/T 7383,and the F test and t test were used to test the precision and accuracy.The results showed that there was no significant difference between this method and GB/T 7383 method.What's more,therewas also no significant difference between the results of acetic anhydride method and phthalic anhydride method,using parallel synthesizer to determine the hydroxyl value.So the accuracy and precision of the results obtained by parallel synthesizer could meet the experimental requirements.关键词
