The purpose of purifying biphenyl is to remove any impurities or contaminants that may be present in the compound. This ensures that the biphenyl is of high quality and suitable for its intended use.
Some factors to consider when choosing a purification method for biphenyl include the solubility of biphenyl in different solvents, the boiling point of biphenyl, and the availability and cost of the chosen method.
Some common methods used to purify biphenyl include recrystallization, vacuum distillation, and column chromatography.
The advantages of using different solvents for purifying biphenyl include the ability to target specific impurities and the ease of solvent removal. However, some solvents may be expensive or toxic, and may not be suitable for certain purification methods.
It is important to wear appropriate personal protective equipment, such as gloves and a lab coat, when handling biphenyl. This compound can also be flammable, so precautions should be taken to avoid ignition sources. Proper ventilation should also be ensured to prevent inhalation of biphenyl vapors.
