Abstract: The subject of the invention is the development of a new process for producing phosphorus P4 from phosphoric acid. In this process, the phosphoric acid and a hydrophilic source of carbon and of hydrogen (biomass, kerogen, “STEP” purification plant sludge, organic polymer) are mixed, and the mixture is treated at a temperature of 80 to 150° C. in order to ensure grafting of the phosphates on the carbon backbone. The production of the phosphorus P4 is carried out by heat treatment of the precursor at a temperature at which phosphorus is produced. The temperature range is from 550° C. to 950° C. This process can be carried out at temperatures below those of conventional phosphorus production without the occurrence of the production of solid by-products normally formed in conventional phosphorus production. The process can be used to produce phosphoric acid for food or medical use.

Abstract: An ionic liquid is used as liquid matrix for organic synthesis in homogeneous phase on soluble support, the ionic liquid being presented in liquid or solid form at ambient temperature, of formula A1+X1?, A1+ representing a cation, functional or non-functional, or a mixture of cations in which either none of the cations is functional or at least one of the cations is functional, and X1? an anion, functional or non-functional, or a mixture of anions in which either none of the anions is functional or at least one of the anions is functional.

Abstract: The present invention relates to a droplet microreactor, i.e. a microreactor consisting of a droplet of a specific liquid, the microreactor being wall-less, wherein the interface of the specific liquid with the ambient environment and with the support on which the droplet is deposited defines the limits of the microreactor. The microreactor is characterized in that it consists of a droplet comprising at least one ionic liquid. The present invention also relates to methods for carrying out chemical or biochemical reactions and/or mixes using said droplet microreactor, and also to a lab-on-chip comprising a microreactor according to the invention.

Abstract: The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula A1+, X1?, wherein A1+ represents a cation and X1? represents an anion.
