“…Because the reaction temperature was maximum 90 °C, polyesterification can be neglected. On the other hand, homopolymerization of maleic anhydride has been evidenced in the presence of typical maleinization catalysts, such as nitrogen bases, leading to dark‐colored products . In this work there was no evidence of these products.…”

BACKGROUND Commercial synthesis of polyunsaturated monomers, like polyester resins, involves an energy‐demanding esterification process, which is usually carried out at 150–220 °C and long reaction times (>12 h). In addition, most of these monomers come from petrochemical sources and, therefore, are not renewable. In this research, a new polyunsaturated monomer was synthesized using crude glycerol from biodiesel production (bioglycerol), through an alternative and efficient process. RESULTS Bioglycerol was transformed to a polyunsaturated resin through maleinization and methacrylation reactions, under mild conditions (<100 °C and 2 h). The effects of temperature and molar ratio of reactants on these reactions were evaluated through a factorial design. The so‐obtained monomer was highly functionalized (5.05 double bonds per molecule) and negligible acid value (<2 mg KOH g−1). To assess its reactivity, the monomer was copolymerized with methyl methacrylate (MMA), affording a rigid material with excellent mechanical properties. In general, the properties were better than those obtained for commercial unsaturated polyester thermosets (flexural modulus, 3783.4 MPa; flexural strength, 161.5 MPa; surface hardness, 76 (Shore D) and Tg, 100.9 °C). This new monomer could also be suitable for the production of other polymers such as alkyd resins. CONCLUSION A new route to polyunsaturated monomers was developed from bioglycerol at relatively low temperatures, without solvents and with minimum intermediate purification stages. The monomer was suitable for reacting with MMA, affording a material with mechanical properties resembling those of a commercial unsaturated polyester thermoset. © 2018 Society of Chemical Industry

“…These polyols were further converted into highly active unsaturated resins through maleinization reactions. Copolymers of these resins with styrene afforded rigid materials with Tg values of 72–152 °C and elastic modulus of 465–2945 MPa, depending on the type of resin and styrene concentration . Moreover, Valerio et al .…”

“…The DAG yield was about 29% at the end of the reaction. On the contrary, Echeverri et al [41] reported that high concentrations of MAG and DAG products were obtained from the beginning of the reaction. The highest concentrations of products (50.4% of MAG and 34% of DAG) were obtained at 30 min and 180°C of time and temperature of reaction, respectively.…”

Diacylglycerol (DAG)-enriched oils have been drawing increased global attention from researchers and food manufacturers. The production of DAG-enriched oils have been investigated extensively because of its health benefit. DAG is commonly produced chemically through glycerolysis processes. This paper attempts to review and summarize the chemical glycerolysis methods for DAG-enriched oils production. The critical process parameters of the DAG synthesis are also presented and discussed. In addition, a process intensification for DAG-enriched oils production has been developed with an objective of reducing required temperature with better reaction yields, and also lowering energy requirement and cost of processing.Practical applications: Diacylglycerol (DAG) has been widely used at different purity levels as an additive for enhancing fats' plasticity, an emulsifier and stabilizer in food as well as in medicine and cosmetic industries. DAG can be produced chemically through a glycerolysis process. Chemical production of DAG oil avoids a number of complex steps required in the enzymatic method. Important parameters in chemical glycerolysis must be fully considered to gain a better performance of chemical glycerolysis.

“…Other waste glycerol uses are the production of castor oil glycerides and polyols. Glycerolysis of castor oil methyl esters and waste glycerol generated castor oil monoglycerides (50.4 %) and diglycerides (35 %) which can be employed in the plastic industries (Echeverri et al 2013). On the other hand, polyols were produced from a sequential two-step liquefaction of lignocellulosic material using crude glycerol as liquefaction solvent.…”

Biodiesel, one of the most important sources of renewable energy, is produced in large quantities around the world; however, its production generates different kinds of residues and by-products which raise economic and environmental concerns. This review presents a compilation of the data on current state of transformation of residues and by-products of biodiesel industry into products that are suitable for bio-refining. The review has analyzed glycerol, biodiesel washing wastewaters, and solid residues. The technologies were described and the most significant experimental results and variables were summarized to allow researchers an easy access to this information.
