What is the synthesis method of 1, 1, 3 - trihydro - 4, 8 - dioxaperfluorononanol

1% 2C1% 2C3 - trihydro - 4% 2C8 - dioxaperfluorononanol that is, 1,1,3 - trihydro - 4,8 - dioxy perfluorononyl alcohol, the synthesis method is as follows:

First take an appropriate amount of perfluorobutylene and place it in a clean reactor. Fully replace the air in the kettle with nitrogen to ensure an oxygen-free environment. Slowly add a certain amount of ether compounds containing specific reactive oxygen atoms. This ether compound needs to be dried in advance to remove moisture impurities.

Turn on the stirring device to fully mix the two, control the stirring rate moderately, and ensure uniform contact of the reactants. Gradually heat up to a specific temperature range. This temperature needs to be precisely adjusted according to the characteristics of the reactants, and should not be too high or too low. Maintain this temperature for a certain period of time, during which the reaction progress is closely monitored, and analytical methods such as gas chromatography can be used.

When the reaction reaches the expected degree, slowly cool down to room temperature. Subsequently, the reaction product is transferred to a separation funnel, and a suitable organic solvent is added for extraction and separation. After the organic phase is dried by anhydrous sodium sulfate, the solvent is removed by rotary evaporation to obtain a crude product.

The crude product is purified by silica gel column chromatography, and a suitable eluent is selected. According to the difference in adsorption and elution characteristics between the product and the impurities on the silica gel, the product and the impurities are separated. Carefully collect the eluent containing the target product, evaporate again to remove the eluent, and obtain high-purity 1,1,3-trihydro-4,8-dioxyperfluorononanol.

The whole synthesis process requires strict control of the reaction conditions and attention to the details of each step, so that the target product can be synthesized efficiently.
