2-PEA is directly used as a rose fragrance in soap industry and in syrup formulations in pharmaceutical industries. 2-PEA is also a starting material for many industrially important aroma chemicals (e.g., synthetic Kevra) and bio-active compounds.
- Non-pyrophoric reusable (up to 100 times) hydrogenation catalyst with high physical strength
- Lesser Pd loading for hydrogenation and recoverable by an easy process
- Recyclable solid urea-like organic promoter for epoxidation (lesser effluent generation)
- Generates no by-products in both steps
- Intermediate styrene oxide is an important chemical for many other processes
Pilot scale (1 Kg)
2-phenylethanol (2-PEA) is a naturally occurring rose fragrant chemical currently used as aroma chemical in perfumery, cosmetic industries and in pharmaceutical formulations. The industry uses Pd/C as hydrogenation catalyst for the production of 2-PEA from styrene oxide which is pyrophoric besides producing several by-products, and due to its low physical strength, there is physical loss of the catalyst during recovery operations. Perfumery industry is expanding and 2-PEA would find improving indigenous market opportunity.
Benign process with low effluent load owing to use of reusable urea-like organic promoter for epoxidation

Some of the licensee have started putting up a plant for commercial scale manufacture of SO/2-PEA though details of their scale of manufacturing is not known
Styrene, Solid urea, manganese sulphate, water, hydrogen peroxide, toluene, ethyl acetate and dichloromethane, Pd/solid base, hydrogen
Reactor, high pressure reactor, distillation unit, centrifugal/filtration unit
Attractive and tentatively the product cost would be ~2-2.5 times that of styrene; Available on request;
Know-how for 2-PEA and SO; Demonstration of the process; License fee, royalty and other financial details are available on request.
