Green chemistry, also called sustainable chemistry, is an area of chemistry and chemical engineering
focused on the designing of products and processes that minimize or eliminate the use and
generation of hazardous substances. A synthesis of benzopinacol from benzophenone is carried out
using ethanol as a solvent. This ia a free radical reaction and reduction of benzophenone occurs by
sunlight via UV radiation. Benzopinacol is the catalyst for the formation of unsaturated polyesters. It is
also used as an organic synthesis intermediate and as an initiator of polymerization by free radicals.
Characterization of Benzopinacol was done by using spectroscopic technique like IR,NMR etc.
Results positively show that solvent ethyl alcohol can be used as an alternative for photoreduction of
benzophenone in case of non availability of isopropyl alcohol.
