烯丙醇无规聚醚的制备方法
摘要：
一种烯丙醇无规聚醚的制备方法，属聚醚的合成技术领域，先用KOH或NaOH，CH3ONa或它们的混合物为催化剂，烯丙醇为起始剂，与环氧丙烷或环氧丙烷和环氧乙烷的混合物反应制得分子量为150～1000的烯丙醇低聚物；再以含有Co，Zn，Pb等金属离子的多金属氰化物(MMC)为催化剂，烯丙醇低聚物为起始剂，与环氧丙烷或环氧丙烷和环氧乙烷的混合物反应制得烯丙醇无规聚醚。本发明采用KOH或NaOH、CH3ONa或它们的混合物催化剂与含有Co、Zn、Pb等金属离子的多金属氰化物(MMC)催化剂相结合，工艺合理，有效提高了烯丙醇无规聚醚的双键转化率和分子量，还使得反应周期缩短、产品质量好、经济实效。
摘要（英）：

The process of preparing random polyallyl alcohol ether belongs to the field of polyether synthesis technology. The process includes the first preparation of allyl alcohol oligomer of molecular weight150-1000 through the reaction of allyl alcohol as initial material and epoxy propane or its mixture with epoxy ethane in the presence of catalyst of KOH, NaOH, CH3ONa or their mixture; and the subsequent reaction of the allyl alcohol oligomer and epoxy propane or its mixture with epoxy ethane in the presence of catalyst of multimetallic cyanide of Co, Zn, Pb, etc to prepare random polyallyl alcohol ether. The present invention has reasonable technological process, effectively raised double bond conversion rate and molecular weight of the random polyallyl alcohol ether, shortened reaction period and high product quality.
