摘要
以聚脂（ＰＥＴ）生产中的残渣Ｒ－１为原料，以Ｃｏ￣（２＋）、Ｍｎ￣（２＋）、Ｃａ￣（２＋）等为催化剂，在温度为２７０－２９０℃、压力为０．０８ＭＰａ下，热解回收了以ＤＭＴ为主的有用成份“粗ＤＭＴ”。
Taking R-1, the residue of polyester production, as rawmaterials and Co￣(2+), Mn￣(2+), Ca￣(2+) and others as catalysts, a useful material“rough DMT”, with DMT as main composition,was recovered un-der the operating temperature of 270～290℃ and the working pressure of 0. 08 MPa.
