    Abstract: PURPOSE:To economically produce a colorless HXO polymer capable of readily carrying out treatment in air and separation of a catalyst after reaction and having high polymerization degree, by heating cyclohexene oxide in the presence of tetraboric acid or anhydrous boric acid. CONSTITUTION:Cyclohexene oxide is heated in the presence of tetraboric acid and/or anhydrous boric acid. The boric acid is added at an amount of >=0.1wt.%, preferably 5-20wt.% based on the raw material. The reaction temperature is 130-200 deg.C.

    Abstract: PURPOSE:To effectively separate a specific isomer from an isomeric mixture of the titled compounds nuclear substituted by chlorine and fluorine atoms, by using faujasite based zeolite as an adsorbent in separating the above- mentioned mixture with an adsorbent. CONSTITUTION:An isomeric mixture of aromatic halogen compounds nuclear substituted by chlorine and fluorine atoms is separated with an adsorbent. In the process, faujasite based zeolite, preferably zeolite X or zeolite Y is used as an adsorbent to selectively adsorb the aimed isomer. Thereby the aimed isomer 3-chloro-4-fluorobenzotrifluoride useful as an intermediate for agricultural chemicals and medicines is extremely readily and economically separated from the above-mentioned isomeric mixture thereof, particularly isomeric mixture of monochloromonofluorobenzotrifluorides in ultrahigh purity.

    Abstract: PURPOSE:To obtain the titled compound useful as an intermediate for pharmaceuticals and agricultural chemicals or a raw material for plastics, in high selectivity and yield, by the thermal reaction of hydroquinone with cyclohexene in an organic solvent in the presence of phosphoric acid as a catalyst. CONSTITUTION:The objective compound can be produced by reacting hydroquinone with cyclohexene in an organic solvent in the presence of phosphoric acid as a catalyst under heating, preferably at 120-180 deg.C, especially at 140-160 deg.C. The phosphoric acid used as the above catalyst is usually preferably a 70-90% aqueous solution of orthophosphoric acid (50.7-65.1% in terms of P2O5) and its amount is most preferably 50-200% based on hydroquinone. The organic solvent is an aromatic hydrocarbon or an aromatic hydrocarbon derivative having a boiling point of >=160 deg.C and preferably having proper solubility of hydroquinone, e.g. mesitylene or propylbenzene. The amount of the solvent is 1-5pts.wt. per 1pt.wt. of hydroquinone.

    Abstract: PURPOSE:To economically obtain the titled compound used as an intermediate for medicine and agricultural chemical, polyester monomer or antioxidant, by heating inexpensive and readily available chlorohexylhydroquinone used as a starting raw material in the presence of a specific catalyst. CONSTITUTION:Cyclohexyl hydroquinone used as a starting raw material compound is heated and reacted in the presence of a catalyst carrying a platinum group metal treated with a divalent sulfur compound normally at 250-500 deg.C, preferably 300-400 deg.C to provide the aimed compound. The platinum group metal used as the above-mentioned catalyst is platinum, ruthenium, etc. and a metal oxide such as silicon dioxide or alumina is used as a support carrying the platinum group metal. The catalyst is produced by carrying the above- mentioned platinum group metal and caustic alkali on the metal oxide and treating the composite with the divalent sulfur compound. An addition amount of the sulfur compound to the catalyst is preferably 0.01-1%.
