Electrochemical process for synthesis of Styrene oxide from Styrene

Description of the

electrochemical

process

Prepared from styrene by using aqueous alkali metal halide as electrolyte

Ionic liquid can also be used as an electrolyte in organic solvent and water

mixture

Advantages of

electrochemical

process

This is an alternative process for the production of styrene oxide by

electrochemical method

It does not use directly the corrosive peroxides and organic peracids for

oxidizing styrene

The electrochemically generated oxidants are eco-friendly and not toxic or air

pollutants

Process efficiency Faradaic efficiency = 90 Energy consumption = 7 kWhkg

Yield= 90 Conversion = 95

Batch Size 01 kg of styrene oxide batch

Applications

Uses

Important intermediate in the manufacture of a range of pharmaceuticals natural

products functional materials perfumery industries and in the synthesis of several

biologically active compounds

Electrochemical process for the preparation of Calcium Gluconate

Electrochemical

Electrolytic oxidation of glucose dissolved in aqueous sodium bromide solution

solution using graphite electrodes

Advantages of

electrochemical

process

Higher yield in comparison with chemical methods

The conversion is high

There is no bye-product formation

Process efficiency

Faradaic efficiency = 90

Energy consumption = 9 kWhkg

Yield= 90

Conversion = 95

Batch Size Calcium gluconate = 1kg Batch

ApplicationsUses

Calcium gluconate is extensively used in the treatment of calcium deficiency both

both for oral and parenteral administration It is also used as an oral antidote for

for fluorine and oxalic acid poisoning

Electrochemical Process for the preparation of Potassium Iodate

Description of the

electrochemical

Applications Uses

Potassium iodate is mainly used in radiation treatment It can replace

radioactive iodine from the thyroid and also used in iodization of edible salts

Description of electrochemical

process

Electrochemical synthesis of quinones and substituted quinones

with high yields ( 85 - 90) from corresponding naphthalene using

electrochemically generated cerium(IV) methanesulphonate

Advantages of electrochemical

process

More economical method than other methods involving inorganic

oxidizing agents because the oxidant can be regenerated and used

has excellent selectivity and avoids disposal of spent reagents

Process efficiency

Faradaic efficiency = 85

Energy consumption = 12 kWh kg

Yield= 80 - 90

Conversion = 95

Batch Size 1 kg batch

Applications Uses

Antibacterial antifungal antiviral insecticidal anti-inflammatory

and antipyretic It is mainly used as a precursor to anthroquinone

Menadione is mainly used as a Vitamin K3

Electrochemical process for synthesis of Styrene oxide from Styrene

Description of the

electrochemical

process

Prepared from styrene by using aqueous alkali metal halide as electrolyte

Ionic liquid can also be used as an electrolyte in organic solvent and water

mixture

Advantages of

electrochemical

process

This is an alternative process for the production of styrene oxide by

electrochemical method

It does not use directly the corrosive peroxides and organic peracids for

oxidizing styrene

The electrochemically generated oxidants are eco-friendly and not toxic or air

pollutants

Process efficiency Faradaic efficiency = 90 Energy consumption = 7 kWhkg

Yield= 90 Conversion = 95

Batch Size 01 kg of styrene oxide batch

Applications

Uses

Important intermediate in the manufacture of a range of pharmaceuticals natural

products functional materials perfumery industries and in the synthesis of several

biologically active compounds
