• isolation of products, very short reaction times (only 10 s), and better yields. The use of glycerol as a starting material is another important advantage because it is the main byproduct in the biodiesel industry and the application of renewable feedstocks for the preparation of suitable chemicals and

• renewable feedstocks in the world [1][2][3]. Moreover, lignin represents the largest source of aromatic compounds among renewables and can be considered as non-food biomass. It usually occurs as a major waste fraction of the pulping industry on a multimillion ton scale [4]. This source has the potential to
