| Abstract: | Microwave assisted extraction for N,N-dimethylformamide from polyurethane synthetic leather was investigated. Factors such as extraction time,power of microwave and material-liquid ratio on DMF re-moval rate were evaluated. The result showed that extraction time of 15 min,microwave power of 700 W, extraction temperature of 80 ℃ and material-liquid ratio of 55： 1. Under the optimal conditions,the con-tent of DMF was 23 mg / kg,the removal rate of N,N-dimethylformamide was 98. 8% . |
