Effect of Diethylenetriamine and Triethylamine Sensitization on the Critical Diameter of Nitromethane’
CP505, Shock Compression of Condensed Matter - 1999 edited by M. D. Furnish, L. C. Chhabildas, and R. S. Hixson 0 2000 American Institute of Physics l-56396-923-8/00/$17.00 EFFECT OF DIETHYLENETRIAMINE AND TRIETHYLAMINE SENSITIZATION ON THE CRITICAL DIAMETER OF NITROMETHANE’ J.J. Lee*, J. Jiang?, K.H. Choong’, J.H.S. Lee’ *Graduate Aeronautics Laboratory, California Institute of Technology, Pasadena, CA 9112.5, USA ‘Dept. of Mechanical Engineering, McGill University, Montr&al, Que’bec, Canada, H3A 2K6 In this work, the critical diameter for detonation was measured for Nitromethane (NM) sensitized with two different amines: Diethylenetriamine (DETA) and Triethylamine (TEA). The critical diameter in glass and polyvinylchloride tubes is found to decrease rapidly as the amount of sensitizer is increased, then increase past a critical amount of sensitizer. Thus the critical diameter reaches a minimum at a critical concentration of sensitizer. It was also found that the critical diameter is lower with DETA than with TEA. INTRODUCTION propagation in various tubes and channels, and the critical conditions for propagation in porous media Previous studies have shown that small (3) . concentrations of certain substances can strongly The effect of DETA on the critical diameter of increase the explosive sensitivity nitromethane NM has been reported by Engelke (4), who (NM). Amines are found to be the most effective performed measurements with up to 2.5% DETA by chemical sensitizing agent for NM with mass in NM. Engelke observed a reduction in the ethylenediamine and diethylenetriamine (DETA) critical diameter of over 50% in the range of DETA producing the largest increase in the card gap value concentrations used. -

Clinical Relevance and Summary of Test Principle a. Clinical Relevance The prevalence of disinfection by-products in drinking water supplies has raised concerns about possible adverse health effects from chronic exposure to these potentially carcinogenic compounds. To support studies exploring the relation between exposure to trihalomethanes (THMs), nitromethane (NM: biomarker for halonitromethanes), methyl tert-butyl ether (MTBE) and adverse health effects, an automated analytical method was developed using capillary gas chromatography (GC) and high-resolution mass spectrometry (MS) with selected ion mass detection and isotope-dilution techniques. -

FIA Technical Regulations for Drag Racing
FIA DRAG RACING SECTION 1 - JUNIOR DRAGSTER & JUNIOR FUNNY CAR 2021 Specific Regulations for FIA Drag Racing These Technical Regulations provide guidelines and minimum standards for the construction and operation of vehicles used in FIA Drag Racing. It is the responsibility of the participant to be familiar with the contents of these Technical Regulations and to comply with its requirements. It is not the responsibility of the officials to discover all potential rule compliance issues. The responsibility for compliance with these Technical Regulations rests first and foremost with the competitor. Additional safety equipment or safety-enhancing equipment is always permitted and the levels of safety equipment stated in these Technical Regulations are minimum prescribed levels for a particular type of competition and do not prohibit the individual competitor from using additional safety equipment. Competitors are encouraged to investigate the availability of additional safety devices or equipment for their type of competition. In disputed cases, whether an item, device or piece of equipment is safety-enhancing or performance-enhancing will be determined by the FIA Technical Delegate or the FIA Technical Department. Furthermore, as to performance-enhancing equipment, it is the general principle that unless optional performance-enhancing equipment or performance- related modifications are specifically permitted by these Technical Regulations, they are prohibited. Throughout these Technical Regulations, a number of references are made for particular products and equipment to meet certain standards and specifications (i.e. FIA-Standard, SFI Specs, Snell, DOT, etc.). It is important to realize that these products are manufactured to meet certainspecifications, and upon completion, the manufacturer labels the product as meeting that standard or specification. -
NMR Chemical Shifts of Common Laboratory Solvents As Trace Impurities
7512 J. Org. Chem. 1997, 62, 7512-7515 NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities Hugo E. Gottlieb,* Vadim Kotlyar, and Abraham Nudelman* Department of Chemistry, Bar-Ilan University, Ramat-Gan 52900, Israel Received June 27, 1997 In the course of the routine use of NMR as an aid for organic chemistry, a day-to-day problem is the identifica- tion of signals deriving from common contaminants (water, solvents, stabilizers, oils) in less-than-analyti- cally-pure samples. This data may be available in the literature, but the time involved in searching for it may be considerable. Another issue is the concentration dependence of chemical shifts (especially 1H); results obtained two or three decades ago usually refer to much Figure 1. Chemical shift of HDO as a function of tempera- more concentrated samples, and run at lower magnetic ture. fields, than today’s practice. 1 13 We therefore decided to collect H and C chemical dependent (vide infra). Also, any potential hydrogen- shifts of what are, in our experience, the most popular bond acceptor will tend to shift the water signal down- “extra peaks” in a variety of commonly used NMR field; this is particularly true for nonpolar solvents. In solvents, in the hope that this will be of assistance to contrast, in e.g. DMSO the water is already strongly the practicing chemist. hydrogen-bonded to the solvent, and solutes have only a negligible effect on its chemical shift. This is also true Experimental Section for D2O; the chemical shift of the residual HDO is very NMR spectra were taken in a Bruker DPX-300 instrument temperature-dependent (vide infra) but, maybe counter- (300.1 and 75.5 MHz for 1H and 13C, respectively). -

In N,N- www.rsc.org/ dimethylformamide (DMF), V12 adopted the guest-free-form (V12-free). By addition of several guest molecules, such as acetonitrile, nitromethane, dichloromethane, the structure conversion to the guest-inserted form (V12(guest)) were observed with the affinity constants of 137±10, 0.14±0.1, and 0.15±0.1 M−1, respectively. In the case of 1,2-dichloroethane, 1,2-dibromoethane, and 1,2-diiodoethane, the constants were 35±5, 114±5, and 2.1±0.5 M−1, respectively, suggesting that the bromo group is best fit to the cavity of the bowl. A cyclic carbonate and 5- and 6-membered lactons, cycrobutanone, and hexanal were inserted to the V12 host, while non-cyclic carbonate, non-cyclic and 7-membered cyclic ester, ketone with a 6-membered ring, and benzaldehyde showed no effect on the guest insertion. -

Development of Initial REACH Exposure Scenarios for Methanol

We followed draft REACH technical guidance documents available during the years 2006•2007 for ES development. The development of ESs included mapping uses and categorizing them, according to operational conditions, into broader scenarios when needed. The exposure data and conditions of use required in the scenarios were gathered from existing measurement reports, new measurements, and through modelling. Preliminary human health and environmental hazard assessment was based on published data or modelling. This project was successful in determining the main Finnish uses of methanol. The mapping of methanol uses in Finland revealed 62 uses, 35 of which were included in the ten exposure scenarios in this project.
