- Phenol tar is a
heavy, viscous byproduct produced in the industrial synthesis of
phenol and acetone.
- Tar by-products
are the bottoms of the last rectification column in the usual
bisphenol-A plant
- Phenol tar is a
complex mixture, which comprises phenol, acetophenon, dimethyl
benzeyl alcohol, alpha-methyl styrene dimmers, p-cumyl phenol,
small amount of salts and many other chemicals in smaller
amounts.
- Typically,
phenol tar comprises the following main components (% by
weight):
Phenol 10-25wt%
Acetophenone 1 0-25
Dimethylbenzylalcohol 3-5
o,p-cumylphenol 20 - 40
Alphamethylstyrene dimer 5-10
Heavy tar The rest to total 1 00%
- Disposal of
phenol tar in an environmentally acceptable manner not easy
- Burning phenol
tar is not good disposal solution because it contains many
ingredients, which do not burn readily, such as phenol.
- Average content
of valuable products such as phenol and bisphenols in the tars
are 20 - 60 %
- There are
methods of catalytic decomposition and catalytic
hydrodestruction in the presence of hydrogen into lower-boiling
products, including initial reagents (phenol and acetone), which
can be recycled into the bisphenol-A synthesis process.
- The most
cheapest procedures employ tar thermal decomposition followed
byseparation of the lighter components formed in decomposition
by rectification, or crystallization
