Hydrochloric Acid → HCID 11982347, compound

Participants

Reaction Steps

400 parts tetrahydrofuran and 55 parts hexaphenylcyclotrisiloxane were added to an Erlenmeyer flask, and dissolution was brought about. 3 parts hexylamine and 40 parts water were then added, and stirring was carried out for 30 minutes at room temperature. Conversion to the diol was confirmed by thin-layer chromatography, and the reaction solution was poured into 500 parts water and neutralized with dilute hydrochloric acid. The organic substance was precipitated with 600 parts of toluene, and this precipitate was repeatedly washed with water. Dehydration was then carried out with anhydrous sodium sulfate, and after filtration, the filtrate was condensed to 150 parts with a rotary evaporator. Hexane was then added to obtain crystals of hexaphenyltrisiloxane-1,5-diol in a yield of 93%.
