摘要：
The Weida Chemical Company, Ltd. under the support of Xiamen University has developed a new technology for manufacturing unsaturated polyester from PTA wastes. PTA wastes are oxidation sludge discharged in the process of PTA production, including PTA, meta-phthalic acid, ben-zoic acid and methylbenzoic acid that are components with definite value. It is difficult to recover these compounds, be-
