ABSTRACT:
A phosphorus-containing hydroquinone derivative represented by a general formula (1):(where R1and R2represent linear or branched alkyl groups that are identical or may be different, and/or R1and R2may form a circular group; X represents an oxygen atom or sulfur atom; Y and Z represent hydrogen atom, hydroxy group, linear or branched alkyl group, aralkyl group, alkoxy group, allyl group, aryl group or cyano group, and/or Y and Z may form a circular group). The present invention provides phosphorus-containing hydroquinone derivatives that are useful for intermediate materials for reactive type flame-retardant agents or phosphorus-containing epoxy resins.
