20140235853 | Method of Preparation of epsilon-2,4,6,8,10,12-Hexanitro-2,4,6,8,10,12-Hexaazaisowurtzitane with Reduced Impact Sensitivity - The present invention relates to a method of preparation of ε-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane with reduced impact sensitivity by precipitation of a solution of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane in a solvent by an antisolvent, wherein phosphorus(V) oxide is added as a recrystallization promoter to the solution of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane in the solvent, the obtained mixture is stirred and filtered, and the filtrate is subsequently precipitated by the addition of the antisolvent. | 08-21-2014 |
20150361056 | CL-20:DNMT COCRYSTAL CRYSTAL STRUCTURE - A cocrystal of CL-20 (2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane) and DNMT (1-methyl-3,5-dinitro-1,2,4-triazole) was formed through a resonant acoustic mixing process. The resulting cocrystal comprised an essentially 1:1 stoichiometric ratio between these coformers. The cocrystal advantageously has decreased sensitivity when compared with a pure CL-20 sample, and maintains thermal stability and comparable energetic performance. | 12-17-2015 |

20080319188 | Novel pyridine derivatives and pyrimidine derivatives (3) - A compound represented by the following formula, a salt thereof or a hydrate of the foregoing has an excellent hepatocyte growth factor receptor (HGFR) inhibitory activity, and exhibits anti-tumor activity, angiogenesis inhibitory activity and cancer metastasis inhibitory activity. | 12-25-2008 |
20110178292 | SYNTHESIS OF CYCLIC AMIDINES - The invention relates to an innovative method for synthesis of cyclic amidines. The synthesis starts from a β-, γ- or δ-lactone which is twofold brominated. After esterification of the carboxyl function, the bromine atoms are nucleophilically substituted and the corresponding diamino compound is obtained. The ring closure to the cyclic amidine is accomplished subsequently by reaction with orthoester, imidate or thioimidate. Owing to interposing additional steps for recovery of the diamino compound in enantiomerically pure form, the enantiomers of the cyclic amidines can be stereoselectively synthesized. | 07-21-2011 |
20140163221 | Process for the Synthesis of Cyclic Alkylene Ureas - The invention relates to a process for the synthesis of cyclic alkylene ureas comprising reacting in the presence of a basic catalyst, a difunctional amine A having two primary amino groups, and an aliphatic organic carbonate component C selected from the group consisting of dialkyl carbonates CD and of alkylene carbonates CA, wherein the ratio of the amount of substance Ji(—NH2) of primary amino groups —NH2 in the difunctional amine A to the sum M(C) of the amount of substance n(CD) of carbonate groups of a dialkyl carbonate CD and the amount of substance n(CA) of carbonate groups in an alkylene carbonate CA, is at least more than 2, and to the product obtained by this process. | 06-12-2014 |
