Abstract: PURPOSE:To obtain the title compound useful as musk perfumes of high quailty in a short time in high yield, by depolymerization and ring closure of a polyester prepared through polycondensation of a dibasic fatty acid and ethylene glycol in the presence of a catalyst of an Al compound having a carbonate radical. CONSTITUTION:CO2 or a substance to generate carbon dioxide, e.g. NaHCO3, is brought into contact with a basic aqueous solution of an Al compound, e.g. Al(OH)3 or aluminum acetate, to give an Al compound having a carbonate radical. A polyester obtained by polycondensation of a dibasic fatty acid of formula I: (n is an integer 6-14) or its ester and ethylene glycol or oxide is subjected to depolymerization and ring closure at a reduced pressure of 10 -1mmHg at 180- 280 deg.c to give a large ring ethylenedioate of furmula II.

Abstract: PURPOSE:To provide a method for producing ethylbenzene in a good yield by the dehydrogenation of a vinylcylcohexene compound. CONSTITUTION:A vinylcylcohexene compound is catalytically reacted in the pressure of a magnesia-containing compound produced by carrying an alkali metal and subsequently treated with oxygen, preferably magnesia, hydrotalcite or its analogous compound, as a catalyst in a solvent-free state at 20-200 deg.C, preferably 40-150 deg.C, to produce ethylbenzene. The amount of the carried alkali metal is preferably 1-15wt.% especially 3-10wt.%, based on the weight of the carrier, and the oxygen treatment is performed by the contact of a mixed gas diluted with an inert gas and having an oxygen concentration of 5-30vol.%, preferably 5-10vol.%, at 25-200 deg.C, preferably 50-150 deg.C. The catalyst is used in an amount of 0.001-1atom, preferably 0.005-0.1atom, as the alkali atom per mole of the raw material.
