General Description

$l^{1}-azane, also known as methylamine, is a chemical compound with the formula CH3NH2. It is a colorless gas with a strong odor, similar to ammonia. Methylamine is used in the production of a variety of industrial chemicals, including pesticides, pharmaceuticals, and plastics. It is also used in the illegal production of the recreational drug methamphetamine. Methylamine is highly flammable and can be harmful if inhaled or ingested in large amounts. It is important to handle and store methylamine with care, following proper safety precautions.

Check Digit Verification of cas no

The CAS Registry Mumber 13774-92-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,7 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13774-92:
(7*1)+(6*3)+(5*7)+(4*7)+(3*4)+(2*9)+(1*2)=120
120 % 10 = 0
So 13774-92-0 is a valid CAS Registry Number.

Absolute rate constants for the reactions of CH with O and N atoms

Messing, I.,Filseth, S. V.,Sadowski, C. M.,Carrington, Tucker

, p. 3874 - 3881 (1981)

CH(X 2Π) was produced by multiple infrared photon dissociation of CH3OH in the presence of excess atomic oxygen or nitrogen.Time-resolved measurements of relative CH concentrations were made at 298 K with a tunable dye laser.Rate constants deduced from the dependence of CH decay rate on atom concentration are (9.5 +/- 1.4) * 10-11 cm3 s-1 for CH + O and (2.1 +/- .5) * 10-11 cm3 s-1 for CH + N.

Very Low Pressure Reactor Chemiluminescence Studies on N Atom Reactions with CHCl3 and CDCl3

Jeoung, Sae Chae,Choo, Kwang Yul,Benson, Sidney W.

, p. 7282 - 7290 (1991)

Ground-state (N(S4)) nitrogen reactions with chloroform-h and chloroform-d were studied by using the VLPR technique at room temperature.Relative N atom concentrations were monitored via mass spectrometry, and their absolute values were determined by the chemical titration reaction with nitric oxide.It was possible to obtain a more accurate rate constant for the bimolecular reaction: N + NO ---> N2 + O, kNO = (2.4 +/- 0.2) x 10-11 cm3 molecule-1 s-1 at298 K.N atom decay in the presence of CHCl3 and CDCl3 was found to have an apparent induction period and to have a large isotope effect.Chemiluminescence signals emitted from the reactor in the range 300-600 nm were also observed, and identified as coming from the excited CN radical.The detailed study of reaction products, intermediates, N atom decay kinetics, and chemiluminescence signals are interpreted by slow reaction of Cl atoms with CHCl3 followed by fast branching chain reactions of N atoms with the intermediate radicals.A successful numerical simulation of the experimental results supports the suggested chain branching mechanism.The following rate constants were estimated from the experimental results: k1(N + CHCl3 ---> NCl + CHCl2), 1.00 x 10-16, k2(N + NCl ---> N + Cl), 2.57 x 10-11, k3(Cl + CHCl3 ---> HCl + CCl3), 3.70 x 10-14, k3D(Cl + CDCl3 ---> DCl + CCl3),0.95 x 10-14, k4(N + CHCl2 ---> HCN + 2Cl), 1.98 x 10-11, k5(N + CCl3 ---> ClCN + 2Cl), 1.67 x 10-11, k6(N + ClCN ---> CCl + N2), 1.00 x 10-14, and k7(N + CCl ---> CN(B2Σu+) + Cl), 5.70 x 10-13, all in the units of cm3 molecule-1 s-1.

Determination of the rate constant for the NH2(X 2B1) + NH2(X2B1) recombination reaction with collision partners He, Ne, Ar, and N2at low pressures and 296 K. Part 1

Altinay, Gokhan,MacDonald, R. Glen

, p. 1353 - 1367 (2012/04/23)

The recombination rate constant for the NH2(X2B 1) + NH2(X2B1) → N 2H4(X1A1) reaction in He, Ne, Ar, and N2 was measured over the pressure range 1-20 Torr at a temperature of 296 K. The NH2 radical was produced by 193 nm laser photolysis of NH3 dilute in the third-body gas. The production of NH2 and the loss of NH3 were monitored by high-resolution continuous-wave absorption spectroscopy: NH2 on the 1221 ← 1331 rotational transition of the (0,7,0)A2A1 ← (0,0,0) X 2B1 vibronic band and NH3 on either inversion doublet of the qQ3(3) rotational transition of the ν1 fundamental. Both species were detected simultaneously following the photolysis laser pulse. The broader Doppler width of the NH 2 spectral transition allowed temporal concentration measurements to be extended up to 20 Torr before pressure broadening effects became significant. Fall-off behavior was identified and the bimolecular rate constants for each collision partner were fit to a simple Troe form defined by the parameters, k0, kinf, and Fcent. This work is the first part of a two part series in which part 2 will discuss the measurements with more efficient energy transfer collision partners CH4, C 2H6, CO2, CF4, and SF6. The pressure range was too limited to extract any new information on k inf, and kinf was taken from the theoretical calculations of Klippenstein et al. (J. Phys. Chem A 2009, 113, 10241) as kinf = 7.9 × 10-11 cm3 molecule-1 s-1 at 296 K. The individual Troe parameters were: He, k0 = 2.8 × 10-29 and Fcent = 0.47; Ne, k0 = 2.7 × 10-29 and Fcent = 0.34; Ar, k0 = 4.4 × 10-29 and Fcent = 0.41; N2, k0 = 5.7 × 10-29 and Fcent = 0.61, with units cm6 molecule-2 s-1 for k0. In the case of N 2 as the third body, it was possible to measure the recombination rate constant for the NH2 + H reaction near 20 Torr total pressure. The pure three-body recombination rate constant was (2.3 ± 0.55) × 10-30 cm6 molecule-2 s-1, where the uncertainty is the total experimental uncertainty including systematic errors at the 2σ level of confidence.

The multichannel reaction NH2+NH2 at ambient temperature and low pressures

Stothard, Nigel,Humpfer, Robert,Grotheer, Horst-Henning

, p. 474 - 480 (2008/10/08)

NH2 profiles were measured in a discharge flow reactor at ambient temperature by monitoring reactants and products with an electron impact massspectrometer. At the low pressures used (0.7 and 1.0 mbar) the gas-phase self-reaction is dominated by a 'bimolecular' H2-eliminating exit channel with a rate coefficient of k(3b)(300 K)=(1.3+/-0.5)E-12 cm**3 molecule**-1 s**-1 and leading to N2H2+H2 or NNH2+H2. Although the wall loss for NH2 radicals is relatively small (k(w)apprxeq.6-14 s**-1), the contribution to the overall NH2 decay is important due to the relatively slow gas-phase reaction. The heterogeneous reaction yields N2H4 molecules.
