IPR Status & Details:
US 6,740,253, US 7,459,139
Application/Uses/Problem being addressed
CSMCRI/CSIR has developed a green brominating reagent - a better alternative to the hazardous liquid bromine. This green brominating agent is an attractive source of bromine for bromination of various organic substrates. The reagent has been designed for three main functionalities
Salient Technical Features including Competing Features/ Impact
Replacement of the corrosive elemental bromine;
Safe, easy to handle & transport;
Avoids the need of special equipments;
Avoids need of catalyst;
Maximum bromide atom efficiency;
Operates under ambient reaction conditions;
Easy to scale-up for the processes development;
No formation of hazardous byproducts;
TRL Level & Scale of Development:- TRL 6 TRL Reference
Kg scale preparation
Business scope & opportunity (in terms of scale, cost, market etc.)
Bromo-compounds manufacturers
Environmental Considerations
The process does not generate hazardous by-products.
Status of Licensing:
Licensed technology
Status of Commercialization:
Not yet commercialized
Major Raw Materials Needed
Bromine intermediate, chlorine and alkali
Major Plant Equipment and Machinery Required
As desired by the customer for the their production.
Techno-Economics
The technology is feasible for the large-scale production of green brominating reagents from the intermediate of bromine manufacturing process. The reagent is equivalent (alternate) to liquid bromine in many transformations
The brominating reagent cost will be approximately equivalent liquid bromine + 20%.
Technology Package
Preparation of non-hazardous brominating reagents ; Pilot scale demonstration
