In the present example, the same procedure was employed as that of Example 1, except that the amounts of ingredients used were varied. In the present example, 4-bis(4-hydroxybutyl)tetramethyldisiloxane (19.08 g, 0.0686 mole), dimethoxydimethylsilane (151.67 g, 1.223 mole) and dimethoxyphenylmethylsilane (222.24 g, 1.219 mole) were used. The crude product, after dried, was passed through a preparative SEC column with a 10percent w/v THF solution (190 mL inject). The purified product was over 97 percent pure with a molecular weight of 4490. |

100% | With hydrogenchloride; In water; for 4.5h;Heating / reflux; | 1,3-bis(hydroxybutyl)tetramethyldisiloxane (13.18 g, 0.474 mole) and dimethoxyphenylmethylsilane (238.08 g, 1.306 moles) were added to a one-liter round bottom flask. Water (23.58 g or 1.31 mole) and concentrated hydrochloric acid (4.8 mL) were then slowly added to the flask and the contents refluxed at 70 degrees Celsius for one hour. After refluxing, methanol (69.2 g) was distilled from the flask and 44 mL of water and 44 mL of concentrated hydrochloric acid were added to the reaction mixture. The contents of the flask were then refluxed for 3.5 hours prior to being poured into a separatory funnel. The silicone layer was separated, diluted with 500-mL ether and washed twice with 100-ml water, twice with 100 mL five percent sodium bicarbonate aqueous solution and twice with 250-mL water. The final organic layer was dried with magnesium sulfate, and then vacuum stripped at 80 degrees Celsius (0.1 mm Hg) to give a clear viscous crude product. The crude product was then purified by silica gel column chromatography using the same method as described in Example 1 above. The THF solutions containing product were combined and dried with magnesium sulfate. The solvent was vacuum stripped to give the final product. The molecular weight of the final product as determined by titration was 2,697. |
