indicate that an ether link brings more hydrophilicity than an ester bond for these types of molecules. The shorter isosorbide monoalkanoates are completely miscible with water and the butanoates are particularly efficient in terms of aqueous solubilization of hydrophobic compounds. In addition, all hydrotropes exhibit some volatility albeit being non-VOC and contrarily to their ethers homologues, isosorbide

Direct upgrading of the biomass-derived sorbitol platform to high-value isosorbide esters is important for efficient utilization of the biomass polyhydroxyl structure, but it is challenging owing to the tandem nature of the reaction and severe side reactions such as isomerization and humin formation. Here we report a simple and efficient approach for the selectivedirect conversion of sorbitol in fatty

fossil-based, impacts related to emissions from energy production dominate the ecological impacts of both routes and scale with the total energy demand. Therefore, Route 2 is currently the greener one in most impact categories (global warming, fossil depletion and human toxicity potential) with the exception of a high water depletion potential (WDP), which is related to the acid anhydride production. If in

The invention relates to a surface treatment method, in which a material other than the human body, which is selected from metallic materials and fibrous materials, is brought into contact with a composition comprising at least one dianhydrohexitol ether (compound A). The dianhydrohexitol ether can be associated with a compound B which is selected from among solubilising agents, acid agents and alkaline agents. The fibrous material to undergo surface treatment is chosen from the following materials in particular, namely: wood materials, vegetable materials, paper materials and textile materials.
