Webbclassical route for Ibuprofen synthesis is the atom economy of the entire steps with a value of 44.04%, a very low value under green chemistry principles that generate a lot of waste. 2.2. The green route for Ibuprofen synthesis In the 1980’s was developed o new route for Ibuprofen synthesis, a green one with only three steps WebbA new catalytic process designed for the synthesis of Ibuprofen by BHC (BHC, 1997) involves three steps, with an atom-efficiency of 80%. Though the usage of HF, a toxic substance, is a drawback of the process, the recovery of HF is effected with 99.9% efficiency. This is a fine example of an eco- efficient process being commercialized.
