摘要:Improved contaminant removal from alkaline- or alkali-earth metal fluoride crystal growth material can be obtained by coprecipitating an alkaline- or alkali-earth metal fluoride with a scavenging agent during synthesis of the fluoride growth material. The coprecipitation of the alkaline- or alkali-earth metal fluoride and scavenging agent can be performed using at least one of chloride, nitrate, hydroxide and carbonate salts of the alkaline- or alkali-earth metal fluoride and scavenging agent. This provides a more intimate mixture or dispersion of the scavenging agent in solid solution or as a mechanical mixture with the alkaline- or alkali-earth metal fluoride for improved outgassing and fewer trapped impurities, leading to improved radiation hardness and bulk absorption.

摘要:The present invention is directed to a method for continuous production of dihydroartemisinin and also artemisinin derivatives derived from dihydroartemisinin by using artemisinin or dihydroartemisinic acid (DHAA) as starting material as well as to a continuous flow reactor for producing dihydroartemisinin as well as the artemisinin derivatives. It was found that the reduction of artemisinin to dihydroartemisinin in a continuous process requires a special kind of reactor and a special combination of reagents comprising a hydride reducing agent, at least one activator such as an inorganic activator, at least one solid base, at least one aprotic solvent and at least one C 1 -C 5 alcohol.

摘要:Carbon fluoride is synthesized by reactively or high intensity/energy milling at ambient room temperature carbon-containing material (such as graphite, carbon black, coke, or other carbon-based material) with an inorganic fluoride agent (such as cobalt trifluoride) other than fluorine gas. The following chemical reaction occurs: xC+CoF 3 →C x F+CoF 2 , wherein x equals 1 to 4. The C x F is separated from the CoF 2 and the CoF 3 by digesting the C x F, CoF 2 and the CoF 3 in hot water of at least approximately 90° C. causing the CoF 2 to dissolve; and then filtering the CoF 2 . The CoF 3 is unreacted and undergoes hydrolysis in the hot water to form Co(OH) 3 or Co 2 O 3 .3H 2 O, which is removed by washing with sulfuric acid. Alternatively, the C x F is separated from the CoF 2 and the CoF 3 by digesting the C x F, CoF 2 and the CoF 3 in heated sulfuric acid followed by filtration and washing with sulfuric acid and then with hot water. The synthesized carbon fluoride is used to form a cathode in electrochemical cells, such as lithium batteries.

摘要:A method is provided for the direct synthesis by living cationic polymerization of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cyano, carbonylamino, cyanato, thiocyanato or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or a tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.
