Claim Text:
1. A method for producing a composition, the method comprising: preparing a raw material composition containing one or two or more compounds selected from a compound group represented by general formula (I), (in the general formula (I), R a represents 0, 1, or 2, M (a) a trans-1,4-cyclohexylene group (one —CH (b) a 1,4-phenylene group (one —CH═ or two or more nonadjacent —CH═ present in the group may be substituted by —N═), and (c) a 1,4-bicyclo(2.2.2)octylene group, a naphthalene-2,6-diyl group, a decahydronaphthalene-2,6-diyl group, a 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, or a chromane-2,6-diyl group, one or two or more hydrogen atoms contained in the group (a), group (b), or group (c) may be each substituted by a fluorine atom, a trifluoromethyl group, a trifluoromethoxy group, or a chlorine atom, and when a represents 2 and a plurality of M Z (in the general formula (III), M (in the general formula (II), R b represents 1, 2, 3, or 4, A (a) a trans-1,4-cyclohexylene group (one —CH (b) a 1,4-phenylene group (one —CH═ or two or more nonadjacent —CH═ present in the group may be substituted by —N═), and (c) a 1,4-bicyclo(2.2.2)octylene group, a naphthalene-2,6-diyl group, a decahydronaphthalene-2,6-diyl group, a 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, or a chromane-2,6-diyl group, one or two or more hydrogen atoms contained in the group (a), group (b), or group (c) may be each substituted by a fluorine atom, a trifluoromethyl group, a trifluoromethoxy group, or a chlorine atom, and when b represents 2, 3, or 4 and a plurality of A Z Y bringing the raw material composition into contact with a purifying agent composed of one or a mixture of silica gel, alumina, and an ion exchange resin after dissolving the raw material composition in an organic solvent or without adding an organic solvent to the raw material composition, and then removing the purifying agent; and when a composition after the purifying agent is removed does not contain the organic solvent, providing the composition as a target composition, and when the composition after the purifying agent is removed contains the organic solvent, distilling off the organic solvent to provide a target composition.
