Yield: 83.7%

Reaction Conditions:

with acetic acid in water;toluene; pH=2

Steps:

3.2; 3.3 Example 3,Preparation of 1,3-bis (hydroxybutyl) -1,1,3,3-tetramethyldisiloxane,The structural formula is as shown in formula (VI):
(2) A single-necked flask equipped with a constant pressure dropping funnel was charged with the product obtained in the step (1), to which a CH3COOH aqueous solution of pH = 2Toluene solution to obtain a hydrolyzate.(3) adjusting the pH of the hydrolyzate to neutral, extracting the organic layer three times with ethyl acetate,Washed three times, dried over anhydrous magnesium sulfate overnight and removed by rotary evaporation of ethyl acetate, To obtain 1,3-bis (hydroxybutyl) -1,1,3,3-tetramethyldisiloxane,The yield is about 83.7%.
