摘要:The present invention relates to the technical field of chemical synthesis, and particularly, a method for improving effect of fluorination reaction in the synthesis of 2-chloro-5-trifluoromethyl pyridine, and a matching system. The method comprises the following steps: preparing 2-chloro-5-trichloromethyl pyridine, and adding to an efficient reaction system after superfine crushing; adding an appropriate amount of iodine pentafluoride, mercury fluoride and a catalyst into the efficient reaction system; controlling the temperature and time, and carrying out a fluorination reaction on materials in the high-pressure, sealed, efficient reaction system to obtain a crude solution containing 2-chloro-5-trifluoromethyl pyridine; purifying the above crude solution to obtain 2-chloro-5-trifluoromethyl pyridine. In the present method, a fluorination reaction is carried out in a high-pressure sealed environment, such that the efficiency and effect of the fluorination reaction are effectively improved. By means of the system in the present invention, the material entering the system may be quickly superfine crushed before the reaction, so as to improve the reaction sufficiency in the subsequent reaction process.

标题 :Synthesis of Alloyed Nanocrystals in Aqueous or Water-Soluble Solvents

摘要:The present invention relates to nanocrystals and methods for making the same; in particular, the invention relates to ternary or higher alloyed nanocrystals and methods for making such structures in aqueous or water-soluble solvents. In certain embodiments of the invention, methods of preparing ternary or higher alloyed nanocrystals involve providing at least first, second, and third nanocrystal precursors (e.g., NaHSe, ZnCl 2 , and CdCl 2 ) and forming nanocrystal structures in an aqueous or water-soluble solvent. In some cases, nanocrystal precursor solutions may also include a water-soluble ligand (e.g., glutathione, GSH). As such, ternary or higher alloyed nanocrystals (e.g., Zn x Cd)— x Se) comprising the at least first, second, and third nanocrystal precursors may be formed, and the water-soluble ligand may coat at least a portion of the surface of the ternary or higher alloyed nanocrystal. Advantageously, methods for forming nanocrystals described herein can be performed at low temperatures (e.g., less than 100 degrees Celsius), and, in some embodiments, do not require the use of organic solvents. The present inventors have applied these methods to prepare blue-emitting nanocrystals with emissions that are tunable between 400-500 nm, and with quantum yields of greater than 25% in aqueous solution. These nanocrystals may be highly water soluble and can be used in a variety of applications, including those involving cell culture, sensing applications, fluorescence resonance energy transfer, and in light-emitting devices.

标 题 :Direct vapor/solid synthesis of mercuric iodide using compounds of mercury and iodine
发明人:SKINNER NATHAN L
权利人:US ENERGY
摘要:A process is disclosed for producing high purity mercuric iodide by passing a gaseous source of a mercuric compound through a particulate bed of a low vapor pressure iodide compound which is maintained at an elevated temperature which is the lower of either: (a) just below the melting or volatilization temperature of the iodide compound (which ever is lower); or (b) just below the volatilization point of the other reaction product formed during the reaction; to cause the mercuric compound to react with the iodide compound to form mercuric iodide which then passes as a vapor out of the bed into a cooler condensation region.
