Design and execute an experimental procedure for testing over-the-counter analgesics such as Excedrin , Tylenol , and Advil for the presence of caffeine (3) and/or acetaminophen (4). A 50 50 (v v) mixture of ethanol and dichloromethane can be used to extract the active ingredients. [Pg.187]

Put the unused eluants containing mixtures of only petroleum ether, acetone, and ethanol in the container for nonhalogenated organic liquids and any unused mixtures containing chloroform in the container for halogenated organic liquids. Put the dry chromatographic plates in the hazardous solid waste container, since they contain small amounts of azobenzene. [Pg.188]

Explain why TLC is not suitable for use with compounds that have boiling [Pg.188]

What may occur if a mixture containing a component that is very sensitive to acidic conditions is subjected to a TLC analysis in which silica gel serves as the stationary phase [Pg.188]
