    • This invention relates to halogenated polyhydroxy compounds of the formulaAr[OR(OH).sub.n-1 ].sub.mwherein 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 formulaAr[OR(OH).sub.n-1 ].sub.mwherein 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 formulaR(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.
    • 本发明涉及式Ar [OR(OH)n-1] m的卤代多羟基化合物,其中Ar是含有2至5个芳环的卤代聚苯基或卤代聚苯基,其中每个所述环中有至少3个卤素原子,R 是脂族烃,脂族醚或含有2-40个碳原子的脂环烃,n和m各自为整数2,3或4,当R为饱和脂族烃n和/或m为3或4时。 本发明还涉及制备式Ar [OR(OH)n-1] m的卤代多羟基化合物的方法,其中Ar是含有2至5个芳环的卤代聚苯基或卤代聚苯基,其中每个所述环具有至少3个卤素 R是脂族烃,脂族醚或含有2-40个碳原子的脂环烃,n和m各自为整数2,3或4,其包括:(a)在约80℃的温度范围内反应, 和2 30℃,含有2至5个芳环的卤代聚苯基或卤代聚苯基,其中每个所述环上具有至少4个卤素原子,在酸受体与式R(OH)n的醇存在下,其中R 是脂肪族烃,脂肪族醚或碳原子数为2〜40的脂肪族烃,n为2,3或4, 和(b)从反应介质中除去卤代多羟基化合物。
