ABSTRACT:
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.
