用中纯度对苯二甲酸生产PET工业化试验

INDUSTRIALIZED EXPERIMENT TO PRODUCE PET BY MEDIUM PURITY TEREPHTHALIC ACID

以中纯度对苯二甲酸为原料,在直接酯化连续缩聚装置上生产 PET.工业应用试验结果表明:把工艺参数作适当的调整,用中纯度对苯二甲酸就能生产出符合企业标准的涤纶树脂.经用户使用,没有发现异常.

Medium purity terephthalic acid was used as raw material to produce PET on direct esterification-con-tinuous polycondensation equipments.Through industrialized application,the result of this experimentshowed that the medium purity terephthalic acid could produce polyester resin accorded with the enterprisestandard by adjusting the process parameters properly.And no abnormal had been found in the applicationsof users.
