Development of vegetable oil and recycling method having high dissolubility of plastic waste

为提高菜籽油中不饱和聚酯废渣的溶出率，研究了催化剂和添加方法。在KOH等6种催化剂的作用下，进行了UP在植物油中的溶解实验。无催化剂的溶解速率为1.6wt%/min。另一方面，在催化剂的作用下，溶解速率提高到3.6wt%/min。用傅里叶红外光谱法对催化剂溶解的植物油进行了分析。没有观察到加催化剂和不加催化剂对溶解油的影响。以植物油溶解UP为回收原料，生产柴油。此外，在UP溶解过程中，通过冷却挥发物质来收集原料。

The catalysts and the addition methods into rapeseed oil were developed to increase dissolution rate of UP (unsaturated polyester) waste. The dissolution experiments of UP were carried out in vegetable oil added six kinds of catalysts including KOH. The dissolution rate was 1.6wt%/min without catalyst. On the other hand, the dissolution rate was increased to 3.6wt%/min with catalyst. The vegetable oil dissolved UP using catalyst was analyzed by FTIR measurement. The difference of dissolution oil with or without catalyst was not observed. Diesel oil was produced from the vegetable oil dissolved UP as recycling method. Furthermore, the raw material had been collected by cooling of volatilization substance during the dissolution of UP.
