Biobased aromatic polyamines were synthesized by thiol-ene coupling with cysteamine on cardanol, a non-edible by-product of cashew nutshell liquid. The cardanol-derived amines were used as hardeners in biobased epoxy networks. Mechanical and thermal properties of the obtained materials showed that these amines could lead to binders for composite applications. Indeed, this biobased amine reactant bears aromatic rings for interesting properties in formulations and has the advantage to use the unsaturations of the aliphatic chain which prevents the plasticization effect.

Microbial oils: A customizable feedstock through metabolic engineering

Microbial oils are considered promising alternatives to fossil fuels as feedstock for the chemical industry. Additionally they present advantages over vegetable oils and animal fats since microorganisms can be easily engineered: i) to accumulate high amount of lipids; ii) to be enriched in a desired kind of lipid; and iii) to facilitate the extraction of the oil from the cells. This short article is intended to present the concept of microbial oils to the general reader, taking into special consideration the malleability of microbial oils by metabolic engineering.

Ethyl rhamnolipids as a renewable source to produce biopolyurethanes

Bio-based polyurethanes were prepared from ethyl rhamnolipids, by reaction with 1,6-hexane diisocyanate (HDI). Rhamnolipids, obtained from fermentation, are an alternative renewable source of reactants for polyurethane production. The unique structure of rhamnolipids may also inspire future synthesis of novel lipid-based polyols.

Native lipase dissolved in hydrophilic green solvents: A versatile 2-phase reaction system for high yield ester synthesis

Lipase CalB is dissolved in the hydrophilic phase consisting of a hydrogen bonding network of solvent and water molecules. Lipase catalysis takes place at the solvent/lipid interface and water is adsorbed into the solvent phase, thus shifting the equilibrium towards ester formation in the water-depleted lipid phase.

New aromatic amine based on cardanol giving new biobased epoxy networks with cardanol

Biobased aromatic polyamine was synthesized by thiol-ene coupling with cysteamine on cardanol, coming from cashew nut shell liquid (CNSL). Cardanol-derived amine was used as hardener in biobased epoxy networks. Mechanical and thermal properties of obtained materials showed that cardanol-derived amine material could lead to binders for composite application.
