Process for converting cellulose and hemicellulose into dimethyl furan, hydrolysing first cellulose in a mixture of N alkyl imidazolium chloride, hydrochloric acid 37% and an alcohol, to produce an acetal of glucose, making the dehydration to an acetal of hydroxymethyl furfural, extracting and makin ...
Process for converting cellulose and hemicellulose in hydroxymethylpyranone and isomers, using as a solvent and catalyst a mixture of N alkyl imidazolium chloride and hydrochloric acid 37%, where hydroxymethylpyranone is extracted with butanol and hydrogenated to methylpyran and isomers.
A biofuel consisting of a mixture of furanic compounds and polymethoxy benzene compounds which can be mixed with standard fuel consisting in hydrocarbons, and the process to obtain these compounds from sugar cane by converting cellulose, hemicellulose and sugars in furan derivatives and levullinic a ...
The present invention relates to glyphosate formulations (herbicides) containing glyphosate and a surfactant consisting essentially of a branched alkylamine where the nitrogen atom in the alkylamine is connected to a branched alkyl group and one, two or three chains of alkylene oxide units (e.g., et ...
Process for obtaining lithium carbonate directly from the mineral containing silicium, aluminum, lithium and other metal oxides without the need to dissolve previously all oxides in sulphuric acid or alkaline hydroxides at high temperatures and pressures, by using carbon dioxide and water at supercr ...
A rechargeable battery with aluminium anode containing a non aqueous electrolyte consisting of an ether as solvent and a lithium salt of an imideIt is welt known that the ionisation energy of aluminium to Al3+ is about 12 times as big as the ionisation energy of lithium to Li1+. The redox potential ...
We propose a rechargeable battery with aluminium anode. In order to avoid the high reactivity of aluminium ions with most liquid electrolytes, we present an electrolyte containing aluminium vapour in plasma state.The battery is contained in a quartz cylinder heated with microwaves to a sufficiently ...
