摘要： The present invention relates to a process for obtaining a dialkyl phthalate and a reusable target PVC plastic from a PVC feedstock containing at least one phthalate, including:
a) solid-liquid extraction of PVC feedstock in the form of particles by placing the particles in contact with a solvent to produce a liquid phase enriched in the phthalate and a solid phase including PVC plastic depleted in the phthalate;
b) transformation of the phthalate of the liquid phase into dialkyl phthalate by transesterification using the solvent;
c) a solid-liquid separation between the solid phase and the liquid phase to produce at least one solid stream including the PVC plastic depleted in the phthalate so as to obtain the target PVC plastic;
d) a liquid-liquid separation of the liquid phase, to produce at least a first liquid effluent including the dialkyl phthalate and a second liquid effluent comprising said solvent.-

摘要： A method for preparing a porous inorganic material by at least: a) reaction of a mixture of one precursor of the oxide of a metal X in solution and a precursor of the oxide of a metal Y at a temperature of between 30 and 70° C., X and Y being, independently aluminum, cobalt, indium, molybdenum, nickel, silicon, titanium, zirconium, zinc, iron, copper, manganese, gallium, germanium, phosphorus, boron, vanadium, tin, lead, hafnium, niobium, yttrium, cerium, gadolinium, tantalum, tungsten, antimony, europium or neodymium; b) mixing of the mixture obtained at the end of a) at a temperature of between 80 and 150° C., the mixing period being adjusted so as to obtain a paste that exhibits a fire loss of between 20% by weight and 90% by weight; c) shaping of the porous inorganic material; a) to c) being performed within an extruder.
