MULTIFUNCTIONAL NANOMATERIALS AND METHODS OF PHOTOTHERMAL HEATING AND CATALYSIS USING THE SAME
The present invention is directed to multifunctional nanomaterials for photothermal heating and catalytic applications. The present invention discloses a method of photothermally heating a solution. The present method also discloses a method of catalyzing a reaction. Both methods require a step of exposing a solution to at least one wavelength of the electromagnetic spectrum. A gold-iron oxide nanomaterial comprising an iron oxide substrate and discrete gold particles deposited on the substrate is also disclosed.
Method to Prepare Phenolics from Biomass
The present invention is directed to a method for preparing a final phenolic product from biomass comprising the steps of providing a furanic compound obtainable from biomass; reacting the furanic compound with a dienophile to obtain a phenolic compound; reacting the phenolic compound further to obtain the final phenolic product.

METHOD FOR THE CONTINUOUS SYNTHESIS OF PARACETAMOL
A continuous paracetamol preparation method, including a nitration step or a nitrosation step to obtain p-nitrophenol or p-nitrosophenol respectively. P-nitrophenol or p-nitrosophenol can then be converted into paracetamol by hydrogenation, followed by acylation. This continuous paracetamol preparation method makes it possible to obtain paracetamol with a very good regioselectivity and excellent yields.
