  • Patent number: 8420837
    Abstract: A stabilized nano-Fe6-iron-crown ether complex is formed by preparing a solution of an iron salt and an olygomer crown compound in dialkylamine or diethylamine. Sodium tetrahydroboron (NaBH4) and dialkylamine or ethylendiamine are added at a temperature of 0-10° C. The mixture is heated to room temperature and boiled, thereby converting the formed iron (II)-borhydride complex (Fe(BH4)2) to a crown ether—iron-hydride complex [CWFe06]·(2H)6. At higher temperature this last complex is converted to the Fe06-crown nanocomposite complex.

  • Patent number: 4363765
    Abstract: A particular process is provided for the recovery of rhodium values from liquid compositions. The process comprises contacting a solubilized rhodium complex with water, a crown ether and an alkaline cesium salt in the liquid phase such that a solid comprising rhodium is formed. The process is applied with particular advantage to the recovery of solubilized rhodium values derived from processes for the production of polyhydric alcohols such as ethylene glycol, and monohydric alcohols such as methanol, by the reaction of carbon monoxide and hydrogen in the presence of rhodium carbonyl complex catalysts in a homogeneous liquid medium. The invention also concerns cesium/crown ether salts of anionic rhodium complexes.
