A process for producing an oligomer comprising contacting a dialkyl carbonate and a dihydroxy compound in a reaction zone in the presence of an oligomerization catalyst under oligomerization conditions to form the oligomer wherein the molar ratio of dihydroxy compound to dialkyl carbonate in the reaction zone is at least 2:1.
一种生产寡聚体的方法,包括在寡聚化催化剂的存在下,在反应区内将二元酸酯和二羟基化合物接触,以在寡聚化条件下形成寡聚体,其中反应区内二羟基化合物与二元酸酯的摩尔比至少为2:1。
