A 2,2',5,5',6,6'-hexafluorobiphenyl-3,3',4,4'-tetracarboxylic acid precursor as an intermediate material for a highly functional fluororesin may be produced at a high yield by reacting tetrafluorophthalonitrile with an alkali metal iodide.

Process for producing hexafluorobiphenyl -3,3',4,4'-Tetracarboxylic acid

Phenol novolak condensate and bis(methoxymethyl)biphenyl for production

There are disclosed a process for preparing 2-hydroxy-2-(6-methoxy-2-naphthyl)propionic acid or 2-hydroxy-(4-substituted phenyl)propionic acid derivative which comprises reacting 2-methoxynaphthalene or substituted benzene derivatives with pyruvic acid in the presence of a Lewis acid and then, if necessary, hydrolyzing the obtained product, and a process for preparing 2-(6-methoxy-2-naphthyl)propionic acid or 2-(4-substituted phenyl)propionic acid derivative which comprises reducing 2-hydroxy-2-(6-methoxy-2-naphthyl)propionic acid or 2-hydroxy-2-(4-substituted phenyl)propionic acid derivative in a lower aliphatic acid in the presence of an inorganic acid under hydrogen atmosphere by using a metal catalyst.
