Benzaldehyde is used chiefly in the synthesis of other organic compounds, ranging from pharmaceuticals to plastic additives.

It is also used for processing of perfume and flavoring compounds and in the preparation of certain aniline dyes.


Salient Technical Features


•  The process is by oxidation of toluene using a recyclable commercial catalyst

  • •  Product meets the market specifications

•  Value added products from the byproduct Benzoic acid also available


Level/Scale of Development


CSIR-IICT has developed the process at 2 kg batch capacity.


Status of Commercialization


The process is ready for demonstration at bench scale, and can be scaled up for pilot/commercial plant of capacity 1 TPD to 100 TPD. Pilot scale studies would be required for the design of commercial plant capacity.


Major Raw Materials to be Utilized


Toluene, Commercial Catalyst

Specific Raw Material Cost is approx. Rs. 142-150/- per kg


Major Plant Equipment and Machinery Required:


Pressure reactors, Stirred vessels, crystallization units, distillation columns & storage tanks.


Technology Package


The scale-up studies and basic design report can be given to the Industry based on the planned capacity of the commercial plant.
