titleOfInvention | Method for producing 4,4'-diformyldiphenylalkane |
abstract | A method for producing a 4,4'-diformyldiphenylalkane represented by the following formula (2), containing formylating a diphenylalkane represented by the following formula (1) with carbon monoxide in the presence of hydrogen fluoride and boron trifluoride, in which the reaction temperature of the formylation is from -50 to 5°C, from 5 to 30 mol of hydrogen fluoride is used per 1 mol of the diphenylalkane, and from 1.5 to 5 mol of boron trifluoride is used per 1 mol of the diphenylalkane:n nwherein R represents an alkanediyl group having from 1 to 6 carbon atoms,n nwherein R represents an alkanediyl group having from 1 to 6 carbon atoms. |
