SULFONATED DERIVATIVES OF CYCLIC PHENOL SULFIDES, PROCESS FOR THE PREPARATION THEREOF, SEPARATING AND RECOVERING AGENTS CONTAINING CYCLIC PHENOL SULFIDES, METHODS FOR SEPARATION AND RECOVERY THEREWITH, AND DRUG COMPOSITIONS CONTAINING THE SULFIDES

A cyclic phenol sulfide represented by the following formula (1) is described: ##STR1## wherein X represents a hydrogen atom, a hydrocarbon group, or an acyl group; Y.sub.1 represents a hydrogen atom, a hydrocarbon group, a halogenated hydrocarbon group, --COR.sup.1, --OR.sup.2, --COOR.sup.3, --CN, --CONH.sub.2, --NO.sub.2, --NR.sup.4 R.sup.5, a halogen atom, --SO.sub.4 R.sup.6, or --SO.sub.3 R.sup.7, in which R.sup.11, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, and R.sup.7 each represents a hydrogen atom or a hydrocarbon group; n is an integer of 3 or more; and m is an integer of 1 to 7, provided that the plural m's of the S.sub.m 's are the same or different; the plural X's are the same or different; and the plural Y.sub.1 's are the same or different. A process for producing the cyclic phenol sulfide is also described.
