Halogenated polyhydroxy compounds and their derivatives

Abstract

This invention relates to halogenated polyhydroxy compounds of the formula Ar[OR(OH).sub.n-1 ].sub.m wherein Ar is a halogenated polyphenyl or halogenated polyphenylbenzene containing 2 to 5 aromatic rings with each of said rings having at least 3 halogen atoms thereon, R is an aliphatic hydrocarbon, an aliphatic ether or an alicyclic hydrocarbon containing 2 to 40 carbon atoms and n and m each is an integer 2, 3 or 4 and when R is a saturated aliphatic hydrocarbon n and/or m is 3 or 4. This invention also relates to a process for preparing halogenated polyhydroxy compounds of the formula Ar[OR(OH).sub.n-1 ].sub.m wherein Ar is a halogenated polyphenyl or halogenated polyphenylbenzene containing 2 to 5 aromatic rings with each of said rings having at least 3 halogen atoms thereon, R is an aliphatic hydrocarbon, an aliphatic ether or an alicyclic hydrocarbon containing 2 to 40 carbon atoms and n and m each is an integer 2, 3 or 4 which comprises: (a) reacting in a temperature range between about 80.degree. and 230.degree. C., a halogenated polyphenyl or halogenated polyphenylbenzene containing 2 to 5 aromatic rings with each of said rings having at least 4 halogen atoms thereon, in the presence of an acid acceptor with an alcohol of the formula R(OH).sub.n wherein R is an aliphatic hydrocarbon, an aliphatic ether or an alicyclic hydrocarbon containing 2 to 40 carbon atoms and n is 2, 3 or 4; and (b) removing from the reaction medium the halogenated polyhydroxy compound.
