Design and optimization of preparation of carboxymethyl cellulose with cassava residual by response surface analysis
摘要
Abstract
The preparation of carboxymethyl cellulose with cassava residual in organic solvent was optimized with Design Expert system. The regression equation expressing the relationship between degree of substitution and the main factors of carboxymethylation was established by stepwise analysis. The R- squared in the model of regression equation was 0.9570. It was indicated that the optimum carboxymethylatione conditions were: 32.7℃ alkalize temperature,the ratio of NaOH/CH2ClCOOH was 2.9,78.5％ organic solvent. In these conditions, it was predicted that the highest DS was 0.59,which increased 40％ over per-optimization.关键词
