摘要:研究了氧化铁纳米团簇的载体性质和电子态对二氯丁烯异构化负载体系催化性能的影响.在含有顺磁性状态的 Feiii 和 Feii 离子的活化二氧化硅基质上,Fe 含量为 2.5 Wt.% 的样品表现出最高的活性.当催化剂上的铁含量高达 15 Wt.% 时,硅胶上铁的活性随着磁性有序的 γ-氧化铁纳米簇的出现而增强.在合成条件下或反应物作用过程中形成两种铁态(feiii 和 Feii),有利于催化剂活性的提高.

标题 :Synthesis of high-purity dialkyl 2-vinylcyclopropane-1,1-dicarboxylate
发明人：CLARK JR CLARENCE E; FAYTER JR RICHARD G
权利人:NAT DISTILLERS CHEM CORP
摘要:This invention relates to a two-step synthesis of high purity dialkyl 2-vinyl-cyclopropane-1,1-dicarboxylate in which a mixture of trans- and cis-1,4-dihalobutene-2 is first isomerized to essentially trans-1,4-dihalobutene-2 followed immediately by cyclocondensing the resultant trans-1,4-dihalobutene-2 with a malonic ester in the presence of an alcoholic solution of a metallic alkoxide.
