Claims
- 1. A method of production of an ether compound expressed by the formula (II): ##STR20## or by the formula (III): ##STR21## wherein R.sup.1 and R.sup.2 are a hydrocarbon group or a hydrocarbon group containing ether oxygens in the main chain, in the side chain or in the both of them, respectively, and may be the same or different from each other and R.sup.3, R.sup.4 and R.sup.5 are a hydrogen atom, a hydrocarbon group or a hydrocarbon group containing either oxygens in the main chain, in the side chain or in the both of them, respectively, and may be the same or different from each other, which comprises bringing an acetal compound or a ketal compound, expressed by the formula (I): ##STR22## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are the same as those in the formulae (II) and (III), into the reaction at a temperature of 10.degree.-250.degree. C. with hydrogen at a pressure of 1.degree.-200 kg/cm.sup.2 in the presence of a solid acid catalyst having hydrogenating ability.
- 2. A method of production of an ether compound as claimed in claim 1, wherein the acetal compound or the ketal compound expressed by the formula (I) is a compound expressed by the formula (IV): ##STR23## wherein R.sup.6 and R.sup.7 are a hydrocarbon group having 1 to 20 carbon atoms or a hydrocarbon group containing ether oxygens, respectively, and may be the same or different from each other, R.sup.6 may be the same or different between the constituting units and n is an integer of 1 to 500, and the ether compound obtained is a compound expressed by the formula (V): ##STR24## or by the formula (VI): ##STR25## wherein R.sup.6, R.sup.7 and n are the same as those in the formula (IV).
- 3. A method of production of an ether compound as claimed in claim 1, wherein the acetal compound or the ketal compound expressed by the formula (I) is a compound expressed by the formula (VII):
- R.sup.8 CH(OR.sup.9).sub.2 (VII),
- wherein R.sup.8 and R.sup.9 are a hydrocarbon group having 1 to 20 carbon atoms, respectively, and may the same or different from each other, and the ether compound obtained is a compound expressed by the formula (VIII):
- R.sup.8 CH.sub.2 OR.sup.9 (VIII),
- wherein R.sup.8 and R.sup.9 are the same as those in the formula (VII).
