Synthesis of Benzhydrol by John Paulo Salak on Prezi

(diphenylmethane) and the secondary alcohol (diphenylmethanol)

Acetaldehyde is available as in part (a). Alkynes such as acetylene are available from the corresponding alkene by bromination followed by double dehydrobromination. Using ethylene, prepared in part (b), the sequence becomes

Sulisobenzone ( benzophenone-4 ) is an ingredient in some sunscreens which protects the skin from damage by UVB and short-wave UVA ultraviolet light

Triphenylmethanol from Benzophenone and Bromobenzene

In Organic Chemistry, oxidation is the formation of C=O bonds or the like,
whereas reduction is the loss of C=O bonds or the like.

In this special synthesis, benzophenone will be reduced by zinc powder
under certain conditions to synthesize benzhydrol.

In this special synthesis, reducing the benzophenone with zinc dust was used.


IUPAC : Diphenylmethanol ((C6H5)2CHOH)
In pharmaceutical manufacture it is used as a fundamental component
in antihistamines, antihypertensive agents and antiallergenic agents.
It is also used as a fixative in perfumery and as a terminating group in polymerizations
is an irritant to the eyes, skin and respiratory system.

Oxidation-reduction reactions (or redox) reactions, are a type of chemical reaction that involves
a transfer of electrons between two species.
