Chem. 2011, 76, 328-331), 13.6 g (54.3 mmol) of boron tribromide was added to a solution of 2.00 g (2.67 mmol) of dimethoxypillar[5]arene in 150 mL of anhydrous chloroform, and the mixture was stirred at 25° C. for 72 hours. Water was added to the reaction mixture, and the ... WebPhenol–chloroform needs to be equilibrated to an adequate pH, and protocol conditions should be optimized. 7 In an effort to improve the safety and ease of use of these protocols, certain modifications have been introduced in order to avoid physical contact with solvents.

This mixture is then centrifuged. Because the phenol:chloroform mixture is immiscible with water, the centrifuge will cause two distinct phases to form: an upper aqueous phase, and a lower organic phase. The aqueous phase rises to the top because it is less dense than the organic phase containing the phenol:chloroform. This difference in density is why phen…
