602-01-7 Usage

Uses

Different sources of media describe the Uses of 602-01-7 differently. You can refer to the following data:
1. 1-Methyl-2,3-dinitrobenzene can be used as an analytical standard for the determination of the analytes in forensic samples, explosive-contaminated groundwater samples, industrial effluents using various chromatographic techniques.
2. 2,3-Dinitrotoluene may be used as an analytical standard for the determination of?the?analyte in forensic samples, explosive-contaminated groundwater samples, industrial effluents and seawater samples by various chromatographic techniques.

General Description

2,3-Dinitrotoluene is classified under the group of nitroaromatic compounds, which are organic nitro derivatives of analytical research interest. It is considered as a ubiquitous environmental contaminant and can adversely affect human health because of its mutagenic and/or carcinogenic nature.

Safety Profile

Moderately toxic by ingestion. Mutation data reported. A skin irritant. When heated to decomposition it emits toxic fumes of NOx. See also 2,4 DINITROTOLUENE.

Purification Methods

Distil the toluene in steam and crystallise it from H2O or *benzene/pet ether. Store it with 10% H2O as it could be EXPLOSIVE when dry. [Beilstein 5 H 339, 5 III 758, 5 IV 865.]

Check Digit Verification of cas no

The CAS Registry Mumber 602-01-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 602-01:
(5*6)+(4*0)+(3*2)+(2*0)+(1*1)=37
37 % 10 = 7
So 602-01-7 is a valid CAS Registry Number.

A process for the preparation of nitrobenzene derivative

-

Paragraph 0049; 0050; 0051, (2016/10/10)

The invention provides a preparation method of nitrobenzene derivatives, which comprises the following steps: mixing aromatic amino-compound with sodium perborate, a titanic acid catalyst and glacial acetic acid, and reacting to obtain nitrobenzene derivatives, wherein the titanic acid catalyst is prepared by reacting isopropyl titanate and oxydol, and the aromatic amino-compound is a compound with an electrophilic substitution group in the ortho-position of the amino group. By using the sodium perborate as the oxidizer and the titanic acid catalyst as the cocatalyst, the reaction yield is up to 80-85%, and the product purity is up to 99% above.

Competition between electron-donor and electron-acceptor substituents in nitrotoluene isomers: A photoelectron spectroscopy and ab initio investigation

Rondino, Flaminia,Catone, Daniele,Mattioli, Giuseppe,Bonapasta, Aldo Amore,Bolognesi, Paola,Casavola, Anna Rita,Coreno, Marcello,O'Keeffe, Patrick,Avaldi, Lorenzo

, p. 5272 - 5282 (2014/01/23)

We present an investigation of the close relationship between chemical structure, physical properties and reactivity of the three nitrotoluene isomers: a joint experimental and theoretical study, based on X-ray photoelectron spectroscopy (XPS) measurements and ab initio calculations, addressing the complex interplay between the competing electron-donor and electron-acceptor effects of the nitro- and methyl-substituents on the chemical properties of the nitrotoluene isomers. As the main results of the investigation we: (i) point out that accurate ab initio calculations play a key role in the complete assignment of photoemission measurements, as well as in the estimate of proton affinities in the case of all the eligible sites; (ii) revisit, at a more quantitative level, textbook models based on inductive and resonant effects of different substituents of the aromatic ring, as well as on the hyper-conjugative connection of the methyl group to the π-conjugated system; (iii) provide an accurate analysis of correlation patterns between calculated proton affinities and core-ionization energies, which represent a powerful tool, capable of predicting site-specific reactivities of polysubstituted molecules in the case of electrophilic aromatic substitution reactions.

PRODUCTION OF ISOCYANATE USING CHLORINE RECYCLE

-

, (2008/06/13)

A process and a system produces isocyanate and converts anhydrous hydrogen chloride, which is a by-product of isocyanate production, to chlorine gas in an electrochemical cell. The chlorine is recycled to the isocyanate process. Any unreacted anhydrous hydrogen chloride may be recycled to the electrochemical cell. By recycling the anhydrous hydrogen chloride and the chlorine, the process and system are able to reduce the cost of producing isocyanate. In addition, this process and system process eliminate or at least substantially minimize the problems associated with disposal of anhydrous hydrogen chloride by turning it into a useful starting material in the isocyanate process.
