Procedure
1.02 g of the above (2A) (1.25 mmol) and 10 mL of a 10 wt % Pd/C (0.0203 g) ethyl acetate solution were mixed, and stirred for 2 days in a hydrogen atmosphere at room temperature. The solution was filtrated by Celite and then concentrated to obtain a colorless oily material of 1,11-bis[4-(4-aminophenoxy)butyl]-1,1,3,3,5,5,7,7,9,9,11,11-dodecamethylhexasiloxane (3A) (0.943 g, 99% of yield) represented by the following formula. Various measurements were carried out with regard to the obtained (3A), and results are shown below.
