摘要:The present invention relates to a method for the synthesis of nanofluids including functionalization of carbon nanostructures through a new method comprising the addition of carbon nanostructures to water; ultrasonication of the solution; addition of persulfate salt and one or several metal hydroxides of the first column of the periodic table to the aqueous solution containing carbon nanostructure; re-exposing the solution to ultrasonic waves; and then, the separation of the functionalized carbon nanostructures from the solution and washing the carbon nanostructures with water to neutralize them and mixing the nanoparticles obtained from the previous step with the fluid. By presenting a new method for the synthesis of the functionalized carbon nanostructures with specific amount of functional groups and their application in the synthesis of nanofluids, an increase in the stability and thermal conductivity of nanofluids takes place.

摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.

摘要:The subject of this invention is a method of synthesis of of hybrid compounds of polyaniline and application of hybrid compounds of polyaniline. n The method consists in that to an ice water cooled acid solution, selected from the group of orthophosphoric acids of a concentration of 0.1 - 6 M, or hydrochloric, hydrofluoric, nitric and sulfuric acid of a concentration 0.1 - 8 M, containing an oxidizer in a form of dissolved ammonium persulfate (NH 4 ) 2 S 2 O 8 in the amount of 10.0 - 20.0 g and 5.0 - 20.0 g of ammonium heptamolybdate tetrahydrate (NH 4 ) 6 Mo 7 O 24 x 4 H 2 O), 5.11 g of aniline is added, whereby the cooled solution is stirred for at least 1 hour, and then left for at least 4 hours at an ambient temperature, and after sedimentation the dark-green precipitate of polyaniline heptarilolybdate is filtered, thoroughly rinsed with distilled water until the filtrate is colorless and finally dried at 378 K for at least 8 hours. Application consists in that the polyaniline heptamolybdates, added in the amount of 0.1 to 5 mass %, play a role of inhibitors, enhancing corrosion resistance of coatings made from epoxy resins, water soluble polyvinyl, acryl and alkyd epoxy paints, and paints dissolved in two-component solvents.

权利人:UNIV KING ABDULAZIZ
摘要:Provided are synthesis methods of polymerizing aniline or derivatives thereof. The production of polyaniline or polyaniline derivatives is controlled by the type of oxidant added in the reaction medium. The methods include the step of using a safe and environmentally friendly carbomethyl cellulose (CMC) or modified CMC as an oxidant in the polymerization reaction to produce polyaniline or aniline derivatives. Synthesis methods of producing O-CMC and O-CMC-S oxidants are also provided herein.
