Abstract

An experiment for the synthetic undergraduate laboratory is described in which zeolite 5A catalyzes the room temperature dehydration of diphenylmethanol, (C₆H₅)₂CHOH, producing 1,1,1′,1′-tetraphenyldimethyl ether, (C₆H₅)₂CHOCH(C₆H₅)₂. The reaction proceeds in good yield and purity, and the product is readily characterized by the conventional spectroscopic methods that are normally available to undergraduate students in synthetic chemistry laboratories.

  Abstract:
  Experiments are presented that demonstrate the size-exclusion properties of zeolites and reveal the reason for naming zeolites "molecular sieves". If an IR spectrometer is available, the adsorption or exclusion of alcohols of varying sizes from ...

  Abstract: Most academic chemists are unaware of the restrictions on the use of carbon tetrachloride (which also apply to methyl bromide and to 1,1,1-trichloroethane). It is important that the restrictions be brought to their attention and that academic chemists ...
