3058-38-6 Usage

Chemical Properties

Yellow Solid

Uses

Different sources of media describe the Uses of 3058-38-6 differently. You can refer to the following data:
1. Explosive compound.
2. s-Triaminotrinitrobenzene is an explosive compound.

Hazard

Low toxicity by ingestion and inhalation. A mild eye irritant.

Check Digit Verification of cas no

The CAS Registry Mumber 3058-38-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,5 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3058-38:
(6*3)+(5*0)+(4*5)+(3*8)+(2*3)+(1*8)=76
76 % 10 = 6
So 3058-38-6 is a valid CAS Registry Number.

Hexaaminobenzene as a building block for a family of 2D coordination polymers

Lahiri, Nabajit,Lotfizadeh, Neda,Tsuchikawa, Ryuichi,Deshpande, Vikram V.,Louie, Janis

, p. 19 - 22 (2017)

A family of 2D coordination polymers were successfully synthesized through "bottom-up" techniques using Ni2+, Cu2+, Co2+, and hexaaminobenzene. Liquidliquid and air-liquid interfacial reactions were used to realize thick (~1-2 μm) and thin (10 nm) stacked layers of nanosheet, respectively. Atomic-force microscopy and scanning electron microscopy both revealed the smooth and flat nature of the nanosheets. Selected area diffraction was used to elucidate the hexagonal crystal structure of the framework. Electronic devices were fabricated on thin samples of the Ni analogue and they were found to be mildly conducting and also showed back gate dependent conductance.

Twinned TATB nanobelts: Synthesis, characterization, and formation mechanism

Huang, Bing,Cao, Minhua,Wu, Xinglong,Nie, Fude,Huang, Hui,Hu, Changwen

, p. 6658 - 6664 (2011)

Twinned TATB nanobelts were directly synthesized using a water/AOT/toluene microemulsion system. Here, urea has been used as an aminating agent, which has been proven to play an important role in the formation of such a nanostructure. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and high performance liquid chromatography (HPLC) were used to characterize the composition of the as-synthesized samples. Electron microscopic studies indicated that the morphology and size of the TATB nanobelts can be readily tuned by varying experimental parameters. Transmission electron microscopy (TEM) and selected area electron diffraction (SAED) studies showed that the TATB nanobelts possess mirror symmetry, each of which grow along the [001] direction. A possible mechanism was also proposed to account for the growth of these twinned TATB nanobelts prepared by the microemulsion system. The Royal Society of Chemistry 2011.

Safe synthesis method of 1,3,5-triamino-2,4,6-trinitrobenzene

-

, (2021/06/23)

The invention provides a safe synthesis method of 1,3,5-triamino-2,4,6-trinitrobenzene, wherein the safe synthesis method comprises the steps: based on the isomerism characteristics of 1,3,5-cyclohexyltriketone imine and 1,3,5-triaminobenzene, taking 1,3,5-cyclohexyltriketone as a reaction raw material, and preparing N,N',N''-triacetyl-1,3,5-triaminobenzene through a trioximation reaction, an N-O bond cleavage-isomerism reaction and an N-acylation reaction; and taking N,N',N''-triacetyl-1,3,5-triaminobenzene as a raw material, and preparing TATB through a multi-stage one-pot tri-nitration reaction. The method has the significant characteristic of the multi-stage one-pot tri-nitration reaction, so that the amination step of an explosive multi-nitro-compound is avoided so as to substantially improve the safety, the used reactants or the used catalyst is the common product in the chemical industry, the use of a non-degradable organic solvent is avoided, the green and safe synthesis is achieved; and meanwhile, on the basis of the characteristics of a one-pot method, the operation process is simplified, operations such as separation, purification and collection of an intermediate product are avoided, and large-scale preparation of 1,3,5-triamino-2,4,6-trinitrobenzene is facilitated.

Method of purifying TATB

-

Paragraph 0020; 0023, (2020/08/09)

The invention discloses a method for purifying TATB. In a polar aprotic organic solvent under mild conditions, high-activity aromatic isocyanate is reacted with TATB to generate substituted urea; thehydrogen-bond interaction between substituted urea molecules is weak so that the substituted urea compared with TATB is more easily dissolved in a polar aprotic organic solvent; and then through adding water or ethyl acetate into the polar aprotic organic solvent in which the substituted urea is dissolved to change the polarity of the solvent so as to crystallize and separate out the substituted urea, pure substituted urea can be obtained; and finally the substituted urea is hydrolyzed under alkaline or acidic conditions to obtain the high-purity TATB. According to the purification method, thephenomenon that concentrated sulfuric acid releases heat violently and has the strong corrosion property is avoided, the purification condition is mild, operation is safer, and compared with imidazole acetate ionic liquid, the cost is low, and the purity is high. The TATB reacts with the aromatic isocyanate to generate the substituted urea, the TATB can be greatly promoted to be dissolved in thepolar aprotic organic solvent, the substituted urea is completely converted into TATB after being hydrolyzed, and the yield and purity of the TATB can reach 99% or above.
