Uses

Phenol has been in production since the 1860s. One of the early uses for phenol was as an antiseptic. Towards the end of the 19th century, industrial scientists found new uses for phenol in the synthesis of dyes, aspirin, and one of the first high explosives, picric acid. As early as 1872, it was found that phenol could be condensed with aldehydes (for example methanal) to make resinous compounds, a process still in use today.

Phenol-methanal (formaldehyde) resins are the basis of the oldest plastics, and are still used to make low cost thermosetting plastics such as melamine and bakelite, used in electrical equipment. These resins are also used extensively as bonding agents in manufacturing wood products such as plywood and MDF.

 

 

 

 

 

 

Phenol is also used to make chemical intermediates for a wide range of other applications, ranging from plastics to pharmaceuticals and agricultural chemicals.
