Document Type and Number:
Japanese Patent JP4510972
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an easy and economical method for dechlorinating an aromatic chlorine compound without presenting danger by which the reaction is finished even under a mild condition. SOLUTION: Acrol 1254 (5.00 g, 15.32 mmol) and triethylamine (9.23 g=12.70 ml, 91.21 mmol) are dissolved in methanol (50 ml) in 100 ml eggplant-shaped flask, and 10% Pd/C (0.15 g, 3 wt.%) is added thereto. The reaction vessel is degassed by an aspirator while stirring the solution, and attached to a catalytic reduction apparatus filled with hydrogen. Nothing except the peak of biphenyl present at the vicinity of 4.8 min is observed in the chart (B) of GC- Mass chromatography of the solution after continuing the stirring for 6 hr at room temperature. As a result, the concentration of the Acrol 1254 is reduced to <=0.5 ppm which is the limit of detection by the GC-Mass chromatography by the previous reaction. (A) is a chart of the Acrol 1254 before the reaction.
