Bis-hydroxyphenyl-n-alkanes are prepared by contacting dicarboxylic acids or dicarboxylic acid derivatives with fluorine-containing organic sulphonic acids, where appropriate with the addition of a phenolic compound, and converting the alkanediones, which are thus obtainable, into bis-hydroxyphenyl-n-alkanes by hydrogenation and, where appropriate, an additional ether cleavage. The invention also relates to new bis-hydroxyphenyl-n-alkanes and to new alkanediones.
双羟基苯基-n-烷烃是通过将二羧酸或二羧酸衍生物与含氟有机磺酸接触制备的,必要时可以加入酚类化合物,并通过加氢将获得的烷二酮转化为双羟基苯基-n-烷烃,同时,必要时还可以进行额外的醚裂解。该发明还涉及新的双羟基苯基-n-烷烃和新的烷二酮。
