Versuchsvorschrift

28.7 g p-trimethylsilylphenoxytrimethylsilane was dissolved in 9 ml 95 percent ethyl alcohol. One drop of concentrated hydrochloric acid and 4 ml water were added, and the mixture was shaked for 5 minutes. After standing for another 15 minutes, the mixture was washed two times with 30 ml water and separated. The organic phase was poured into a crystallizing dish; p-trimethylsilylphenol crystallized out as white needles. After drying overnight in vacuo, 18.7 g of product was obtained (mp 76 degrees Celsius).
