1 Introduction

Phenol is an aromatic organic chemical compound with the

formula

Phenol is a white crystalline soid that is volatile.

Phenol is molecule consists of a phenyl group bonded to a

hydroxyl group(−OH) Mildly acidic, it requires careful handling because it can cause chemical burn

Phenol is mainly used for two purposes, as a raw material in

the manufacture of synthetic fibers (nylon) and for plastics

It is identified by some of it properties such as:

+ Molecular weight : 94.11 + Melting point : 40.5 + Boiling point : 181.7+ Density at 20 : 1.072

4 Economic data

The global phenol market size reached a value of USD 23.17 billion in the year

2020 The phenol market is further expected to grow at a CAGR of 5.3% between

2021 and 2026 to reach a value of about USD 30 billion by 2026

4 Economic data

In 2020, Asia Pacific was the largest regional phenol market with a market share of about 40%

Europe and the United States as the leading markets for the product with Europe occupying 29% of the global phenol market and the United States accounting for about 26% of the industry

China, on the other hand, was the largest importer of phenol in the world

5 Application

Phenol finds extensive and diverse applications, especially through its downstream products It finds the majority of its usage in the conversion to precursors for plastics In the pharmaceutical sector, phenol finds its application as a precursor of drugs like aspirins, and other pharmaceutical drugs

It is also employed as a remedy for pharyngitis It is derived through the Cumene process, Dow process, and Raschig–Hooker process, among others
