Formation of the imidazolinone ring under mild conditions in the presence of sodium hydride.
Substituted imidazolinones containing heterocyclic carboxylic acids as substituents and possessing herbicidal properties were synthesized by cyclization of 2-amino-2,3-dimethylbutyramide with heterocyclic ethyl dicarboxylates under mild conditions. The use of NaH as base leads to a significant increase in the reaction rate and allows the preparation of the target compounds in high yields.
متن کاملA generalized kinetic model for the formation and growth of single-walled metal oxide nanotubes
We demonstrate a generalized kinetic modeling and experimental approach to describe the formation and growth of single-walled metal oxide nanotubes. These materials can now be synthesized using solution-based methods at temperatures as low as 95 1C. Ultimately, it is desired to produce nanotubes on a larger scale (e.g., kilogram or ton) for technological applications. However, a quantitative mu...
متن کاملGrowth of Oxide Compounds under Dynamic Atmosphere Composition
Commercially available gases contain residual impurities leading to a background oxygen partial pressure of typically several 10 bar, independent of temperature. This oxygen partial pressure is inappropriate for the growth of some single crystals where the desired oxidation state possesses a narrow stability field. Equilibrium thermodynamic calculations allow the determination of dynamic atmosp...
متن کاملSTRUCTURAL INTEGRITY CHANGES IN THE Zr-Nb ALLOY DURING HYDRIDE PHASE TRANSFORMATION UNDER THE THERMAL SHOCK
Structural changes and properties of zirconium alloy subjected to the thermal shock in the solar furnace were investigated. Specimens were prepared from unirradiated cold-worked RBMK Zr-2.5Nb fuel channel pressure tube material after adding hydrogen to the sections of the tubes up to 150 ppm. Tests were done at temperatures up to 1460 C and heating rates 50-83 C per second. After thermal treatm...
متن کاملBubble Formation in Zr Alloys under Heavy Ion Implantation
We report here the results of a study conducted to examine the effect of Kr ion irradiation on bubble formation in Zr alloys. We used the H?EM/Tandem facility at Argonne National Laboratory to irradiate several Zr alloys, including Zircaloy-2 and k d o y 4 , at temperatures from 300 to 800 C and to doses up to 2 x 10'6ion.cm-2. Both in-situ irradiation of thin foils as well as irradiation of bu...
