Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 143-23-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143-23:
(5*1)+(4*4)+(3*3)+(2*2)+(1*3)=37
37 % 10 = 7
So 143-23-7 is a valid CAS Registry Number.

Functionalized multi-walled carbon nanotubes supported Ni-based catalysts for adiponitrile selective hydrogenation to 6-aminohexanenitrile and 1,6-hexanediamine: Switching selectivity with [Bmim]OH

Functionalized multi-walled carbon nanotubes supported nickel-based catalysts were prepared and applied in adiponitrile (ADN) hydrogenation. The characterization results show that different functional groups such as NH2– COOH– OH– on MWCNTs surface can effectively act on metal ions by electrostatic attractions and chemical interactions so as to provide nucleation sites, and N species in MWCNTs can act as active sites for Ni deposition due to the strong electronic interactions between N species and Ni so as to promote ultra-small Ni nanoparticles formation, decrease NiO reduction activation energy, increase zero-valent Ni amounts as well as Ni nanoparticles dispersion. Furthermore, the doped N increases the lewis basicity, which favors the formation of primary amine of 6-aminohexanenitrile (ACN) and 1,6-hexanediamine (HDA). Moreover, the basic ionic liquid [Bmim]OH may switch the selectivity by inhibiting nucleophilic addition of the primary amine to the α-carbon of aldimine via the stabilization of –NH2 groups in the amino-imine intermediates so as to impede by-products formation. In addition, the mechanism for ADN hydrogenation in [Bmim]OH was studied by density functional theory calculations. Under optimized conditions, it gives 97.80% total selectivity to ACN and HDA at 95.34% ADN conversion over Ni/N-MWCNTs-800 in the presence of [Bmim]OH.
A practical method for building linear and cyclic triamines from (2-trimethylsilyl)ethanesulfonamides (SES-amides)

, p. 10165 - 10171 (2007/10/03)
SES-chloride has been obtained in higher yield and purity by improving Weinreb's original procedure, allowing efficient access to the primary SES-amide. Linear triamines can be built conveniently from the SES-amide in high yields, with the potential for orthogonal protection. The modified Richman-Atkins cyclisation of SES-amides allows access to novel biologically interesting triazamacrocycles with combinations of three-, four-, five- and six-carbon bridges within the ring. Purification of the free macrocyclic amines by distillation greatly simplifies the workup, increasing the practicability of multi-gram scale synthesis. Although CsF sometimes provided undesirably low yields in the deprotection step, alternative fluoride sources were found to be unsuitable for the deprotection of SES-triazamacrocycles.
