“…Self‐condensation of glycerol in the presence of appropriate catalysts leading to different structures for rigid/flexible PU foams is also possible . It may be both intermolecular to produce flexible linear polymers, or intramolecular to give cyclic species and branched structures . High functionality low molar mass poly‐glycerols may act as starters for manufacturing rigid polyurethane foams employing different chain extenders …”

Polyols are polymers that contain multiple hydroxyl groups in their structure. They are generally produced from petroleum derivatives and have a relevant commercial value as building blocks, intermediates in organic synthesis, or precursors for production of polyurethanes. New alternatives for green synthesis of polyols involve the substitution of some hazardous petrochemical derivatives by others based on biomass and which are safer and environmentally more benign. This mini‐review assesses the synthesis processes of some relevant biomass polyols, products that are becoming a commercial reality. © 2016 Society of Chemical Industry

Biomass valorization is a booming field. Especially, the valorization of platform molecules by catalytic processes has driven a large interest in the recent years, and many groups are actively working on the transformation of biosourced substrates to a variety of upgraded chemicals. In this context, in the present paper we put in perspectives the scientific works of our research team. We first classified catalytic transformations of industrial interest according to the number of carbons of the starting material, from C1 to C6. They involve, among others, acid catalysts (e.g., for glycerol dehydration), redox catalysts (e.g., for 5-HMF conversion to diformylfuran), acid and redox catalysts (e.g., for direct acetalization of alcohols), or complex multifunctional catalysts, especially for the Guerbet reaction. Further, we also developed what we called 'toolboxes,' which are general concepts or technologies with a broader field of applications. For example, we adapted the two zones fluidized bed reactor (TZFBR) concept to the single reactor continuous regeneration of coking catalysts. Further, we designed a completely new high throughput platform enabling synthetizing, characterizing and testing the performances of many catalysts for considerably accelerating the catalysts discovery/optimization loop.

“…This strongly encourages the manufacturers to produce PGs directly from glycerol. Currently, in Europe, manufacturers such as Solvay Chemicals, Lonza and, recently, Spiga Nord produce PGs from refined glycerol deriving from the biodiesel and oleochemicals industries [2].…”

Polyglycerols (PGs) are biocompatible and highly functional polyols with a wide range of applications, such as emulsifiers, stabilizers and antimicrobial agents, in many industries including cosmetics, food, plastic and biomedical. The demand increase for biobased PGs encourages researchers to develop new catalytic systems for glycerol polymerization. This review focuses on alkaline homogeneous and heterogeneous catalysts. The performances of the alkaline catalysts are compared in terms of conversion and selectivity, and their respective advantages and disadvantages are commented. While homogeneous catalysts exhibit a high catalytic activity, they cannot be recycled and reused, whereas solid catalysts can be partially recycled. The key issue for heterogenous catalytic systems, which is unsolved thus far, is linked to their instability due to partial dissolution in the reaction medium. Further, this paper also reviews the proposed mechanisms of glycerol polymerization over alkaline-based catalysts and discusses the various operating conditions with an impact on performance. More particularly, temperature and amount of catalyst are proven to have a significant influence on glycerol conversion and on its polymerization extent.
