A material that can be used for detecting at least one alkaline element in cationic form chosen from polymers or inorganic materials, the material being functionalised by at least one group, referred to as group A, comprising one or more aromatic rings, the or all or a portion of the aromatic rings comprising at least one imine substituent and the or all or a portion of the aromatic rings comprising at least one atom carrying a free doublet within the or all or a portion of the rings and/or at least one other substituent different from an imine substituent comprising at least one atom carrying a free doublet.

Specific materials that can be used for the detection of at least one alkaline element

A method for manufacturing a compound comprising at least one imine group, the method comprising a step of reaction between a first compound comprising at least one amine group and a second compound comprising at least one carbonyl group, the reaction step being carried out in the presence of at least one supercritical fluid.

Method for preparing a compound comprising at least one imine function by a specific condensation reaction, and particular application of said method in the field of dyeing

In the field of papermaking and more particularly a method for producing paper impregnated with a molecule of interest, particularly colored paper, and the associated product, i.e. impregnated paper, there is a disclosed a method implementing a supercritical-pressure fluid. Such paper, particularly colored paper, obtained from a formulation of paper pulp or paper including latex, does not bleed when it comes into contact with water.

Method for producing paper impregnated by a supercritical-pressure fluid, and impregnated, particularly coloured paper

A method for coloring of cellulose in a supercritical COmedium by an uncharged hydrophobic dye, including at least the steps including of: (i) provision of cellulose fibers, (ii) placing the cellulose fibers in the presence of: a) an effective quantity of at least one uncharged mono organo-urea primer of formula R&#x2014;NH&#x2014;CO&#x2014;NH, where R represents a linear or branched, saturated or unsaturated, hydrocarbon chain possessing at least 3 carbon atoms, or a saturated or unsaturated cyclic hydrocarbon radical, which is bonded directly or via a methylene or ethylene group to a nitrogen atom, and if appropriate substituted under conditions conducive to the forming of a covalent carbamatic bond between the cellulose and the molecules of the organo-urea; and b) at least one hydrophobic dye in a supercritical COmedium, under conditions conducive to the immobilization of the dye on the fibers.

Method for coloring cellulose

These luminescent carbon particles have a carbon core and an external polymeric coating containing at least one luminophore.

Luminescent carbon particles, method for preparation and use

This method of preparing particles having a hydrophilic core coated with a hydrophilic core coated with a hydrophobic polymeric layer includes the steps of: preparing an aqueous phase comprising at least one hydrophilic optical brightener or colorant; preparing an organic phase including at least one hydrophobic polymer; forming a water-in-oil inverse emulsion by adding the aqueous phase into the organic phase; forming the particles by thermal quenching of the emulsion; and isolating the particles thus obtained.

Process for preparing particles which have a hydrophilic core coated with a hydrophobic polymeric layer

The present invention relates to a process for preparing a porous silica particle comprising a step that consists in preparing a silica particle comprising a water-soluble pore-forming agent then in removing said pore-forming agent by dissolution. It also relates to the porous silica particles capable of being prepared by this process and to their various uses and applications.
