    摘要： The present invention provides an epoxy compound which is 2,2′,7,7′-tetraglycidyloxy-1,1′-binaphthalene. Also, the present invention provides a method for producing [1,1′-binaphthalene]-2,2′,7,7′-tetraol, the method including a step of bringing a crude product produced by dimerization reaction of naphthalene-2,7-diol or a naphthalene-2,7-diol derivative into contact with an aromatic solvent; a step of separating [1,1′-binaphthalene]-2,2′,7,7′-tetraol dissolved in the aromatic solvent from insoluble substances; and a step of removing the solvent from a solution of [1,1′-binaphthalene]-2,2′,7,7′-tetraol. The present invention also provides a method for producing an epoxy compound, the method including reacting [1,1′-binaphthalene]-2,2′,7,7′-tetraol or [1,1′-binaphthalene]-2,2′,7,7′-tetraol monohydrate with epihalohydrin.

    摘要： A vertical reactor system having a plurality of substantially vertically aligned reaction compartments one on top of the other, the reactant materials (and catalyst and solvent, if desired), flowable from a first top compartment through intermediate compartments, if any, to a bottom compartment from which a desired product of a reaction of the reactant materials is withdrawn, the compartments having inlets for the addition of additional reactants, catalysts, or solvents and outlets for withdrawing by-products, vapors, and water from any compartment, and processes for producing products using such a system. In one embodiment the product is a liquid epoxy resin. Stirring impellers may be provided in any compartment. A liquid seal may be provided on a shaft for the impellers and, in one embodiment the seals in each compartment may be elevated above the liquid in the compartments.
