  • Patent number: 5463102
    Abstract: Organic carbonates containing at least one aromatic ester group can be obtained in a continuous manner from carbonates containing at least one aliphatic ester group and a phenolic compound in the presence of a transesterification catalyst known per se by carrying out the reaction in at least two stirred containers connected one behind the other in such a way that, in each case, the phenolic compound is metered in liquid form into the first stirred container and the carbonate containing at least one aliphatic ester group is metered in liquid form into one or more of the stirred containers. The carbonate containing at least one aromatic ester group is removed in liquid form from the last stirred container. Volatile reaction products, for example alcohol which has been cleaved out or a dialkyl carbonate are removed in gaseous form from one or more stirred containers.

  • Patent number: 5463082
    Abstract: Stoichiometric and catalytic chemical transformations may be carried out in solution using novel fluorous multiphase systems (FMS). The term "fluorous" is defined as a carbon-fluorine bond rich organic molecule. The FMS consists of a fluorous phase containing a fluorous solvent, typically a fluorocarbon or a fluorohydrocarbon and a reagent or a catalyst containing a sufficient number of fluorous moieties to render it preferentially soluble in the fluorous solvent without impairing the ability of the catalyst or reagent to be effective in the reaction and while maintaining the reaction in a liquid or fluid phase. The nonfluorous solvent may be any suitable organic or nonorganic solvent(s) with limited or no solubility in the fluorous solvent that is effective for dissolving the reactant(s) and most desirably, for separating the resulting product(s). Typically, such solvents have a Hildebrand solubility parameter of at least about 18.0 MPa1/2.

  • Patent number: 5461166
    Abstract: Disclosed are a conductive thienyl derivative monomolecular film covalently bonded to a substrate surface and method of manufacturing the same, and a silicon compound comprising 3-thienyl groups (thiophene derivative) used for forming the conductive monomolecular film and a method of manufacturing the same. A monomolecular ultrathin film comprising 3-thienyl groups and silicon groups is formed in the invention. The silicon compound used for forming the film is provided by reacting .omega.-(3-thienyl)-1-alkene compound to a monosilane derivative compound, in which three out of four hydrogen atoms of monosilane are replaced with halogen or alkoxy groups, in the presence of a transition metal catalyst. A substrate is dipped and held in a nonaqueous solution of the above-noted compound, thus chemically bonding the monomolecular film to the substrate surface. Furthermore, a thienyl derivative ultrathin film is formed by the electrolytic or catalytic polymerization of the monomolecular film.
