Reaction Conditions

Reaction Steps

A solution of 3,4-dihydroxybenzonitrile (5.00 g, 37.0 mmol) and toluene (45 ml) was dehydrated by distilling 5 mL of the solution. Thereafter, 5.25 g (18.5 mmol) of titanium(IV) isopropoxide (TTIP) was added to the solution while stirring. The mixed solution was refluxed for 1 hour, and then, while the distillation temperature was 100° C. or higher, distilled until the amount of the solution became half. After the distillation, solid content of the product was isolated by suction filtering using a membrane suction filter. The residual solid content was heated to 100° C. under vacuum using a vacuum dryer so that remaining volatile components were completely removed. The solid content (3,4-dihydroxybenzonitrile-titanium complex) was brown in color. The yield amount was 5.80 g (18.5 mmol), and the yield percentage was 100%. 3.14 g of 3,4-dihydroxybenzonitrile-titanium complex was dissolved into 100 mL of ethanol to produce a coating liquid.
