ACTION: Final rule. SUMMARY: In this final rule, the Bureau of Industry and Security (BIS) amends the Export Administration Regulations (EAR) to implement the rescission of Sudan’s designation as a State Sponsor of Terrorism (SSOT). The Secretary of State rescinded this designation effective December 14, 2020 in accordance with established statutory procedures, including the President’s October 26, 2020 submission to Congress of a report justifying the rescission and certifying Sudan had not provided any support for acts of international terrorism during the preceding six month period and that Sudan had provided assurances that it would not support acts of international terrorism in the future. Accordingly, BIS amends the EAR by removing Anti-Terrorism (AT) controls on the country and by removing Sudan from Country Group E:1 (Terrorist supporting countries). These actions render the country eligible for a general 25 percent de minimis level. As a consequence of these actions, as well as the addition of the country to Country Group B, Sudan is also potentially eligible for several new license exceptions under the EAR. -

The Hague: Health Council of the Netherlands, 2005; 2000/15OSH/153. all rights reserved 1 Introduction The present document contains the assessment of the health hazard of 2,2’- iminodi(ethylamine), in this document referred to as DETA (diethylenetriamine), by the Committee on Updating of Occupational Exposure Limits, a committee of the Health Council of the Netherlands. The first draft of this document was prepared by AAE Wibowo, Ph.D. (Coronel Institute, Academic Medical Centre, Amsterdam, the Netherlands). The evaluation of the toxicity of DETA has been based on the reviews by the Nordic Expert Group for Criteria Documentation of Health Risks from Chemicals (And94), the Swedish Criteria Group (Lun95), and the American Conference of Governmental Occupational Hygienists (ACGIH) (ACG96). Where relevant, the original publications were reviewed and evaluated as will be indicated in the text. In addition, in December 1997, literature was searched in the databases Medline, Chemical Abstracts, Embase (starting from 1966, 1970, and 1988, respectively), and HSELINE, NIOSHTIC, CISDOC, and MHIDAS (backwards from 1997) and Poltox (Toxline, Cambr Sc Abstr, FSTA) (backwards from 1994), using the following key words: diethylenetriamine, aminoethylethanediamine, diaminodiethylamine, iminobisethylamine, and 111- 40-0. In July 2000, the President of the Health Council released a draft of the document for public review. -

An Efficient, Heterogeneous and Green Catalyst for Organic Synthesis

These include catalytic reactions for organic synthesis, chemical evolution, the mechanism of humus-formation, and environmental problems. Catalysis by clay minerals has attracted much interest recently, and many reports including the catalysis by synthetic or modified clays have been published. In this review, we will limit the review to organic reactions using Montmorillonite clay as catalyst. Keywords: Montmorillonite, catalysis, clay, organic synthesis, green chemistry. ______________________________________________________________________________ INTRODUCTION One of the major current challenges before chemists is to develop synthetic methods that are less polluting, i.e., to design clean or 'green' chemical transformations. The chemical manufacturing processes should be such that they do not cause permanent damage to the environment or disturb the ecological balance. Ways to minimize the consumption of energy and raw materials used in synthesis must be devised so that optimal value of resources could be realized. Thereby environmentally benign products are obtained at affordable costs. Such a concept, though not new, has received enormous attention in recent times. The desire to make chemical manufacturing environmental friendly is not a new one. Such awareness was there even among the nineteenth century chemists, industrialists and lawmakers. The problem has become more acute in recent times and has received wider attention because of our better understanding of the causes of environmental degradation. -

The Role of Product Composition in Determining Detonation Velocity
The Role of Product Composition in Determining Detonation Velocity... 459 Central European Journal of Energetic Materials, 2014, 11(4), 459-474 ISSN 2353-1843 The Role of Product Composition in Determining Detonation Velocity and Detonation Pressure Peter POLITZER*, Jane S. MURRAY Department of Chemistry, University of New Orleans, New Orleans, LA 70148, USA *E-mail: [email protected] Abstract: Four sets of rules for predicting the detonation product compositions of explosives have been investigated: the Kamlet-Jacobs, the Kistiakowsky- Wilson, the modified Kistiakowsky-Wilson and the Springall-Roberts. These can result, for a given compound, in significantly differing detonation products and amounts of heat release. However the resulting detonation velocities D and detonation pressures P obtained for the compound using the Kamlet-Jacobs equations are generally quite similar, with the Kamlet-Jacobs rules leading to the D and P that are, on average, closest to the experimental. The fact that the variations among the D and P values are relatively small can be attributed to a balancing of opposing effects relating to the quantities of gaseous products and the heat releases. Accordingly, obtaining reasonable accuracy for D and P does not necessarily imply corresponding accuracy for the product composition and heat release that were used. The analysis presented explains the observations that D and P can be correlated with loading density alone, even though product compositions are known to change with density. Keywords: detonation velocity, detonation pressure, density, detonation product composition, detonation heat release 1 Detonation Performance Two key criteria for evaluating explosives are detonation velocity (D) – the stable velocity of the shock front that characterizes detonation – and detonation pressure (P) – the stable pressure that is developed behind the front [1-6].
