Paragraph 0070; 0072-0077, (2018/12/14)
The invention relates to a green synthesis method for 1,2-bi(trialkyl siloxy) cyclohexene. The method comprises the step of causing 1,2-cyclohexanone, bi(trialkyl silicon) sulphate and reactive metalreact in an inert solvent, thereby acquiring 1,2-bi(trialkyl siloxy) cyclohexene. The bi(trialkyl silicon) sulphate is prepared according to the steps of preparing hexalkyl disiloxane by dehydrating by-product trialkyl silanol in consequent reaction and then continuing to react with concentrated sulfuric acid. The environmental issue of siloxane effluent is completely solved through the recyclingof silicon protecting group; the produced solid waste has a single component and can be prepared into byproduct for sale after simple treatment; the emission of three wastes is less; the technology isenvironment-friendly.
