63697-18-7 Usage

General Description

1,2,4-trichlorobenzene is a chemical compound with the molecular formula C6H3Cl3. It is a type of chlorobenzene, which is a group of chemicals used in various industrial applications including as solvents and chemical intermediates. 1,2,4-trichlorobenzene is a colorless liquid with a sweet odor, and is insoluble in water. It is commonly used as a precursor for the production of other chemicals, and in the synthesis of pharmaceuticals, pesticides, and dyes. However, it is also considered to be a hazardous chemical and is classified as a potential environmental pollutant and toxic substance, with harmful effects on human health and the environment. Therefore, proper handling and disposal practices are necessary when dealing with 1,2,4-trichlorobenzene.

Check Digit Verification of cas no

The CAS Registry Mumber 63697-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,6,9 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 63697-18:
(7*6)+(6*3)+(5*6)+(4*9)+(3*7)+(2*1)+(1*8)=157
157 % 10 = 7
So 63697-18-7 is a valid CAS Registry Number.

Iron(iii)porphyrin electrocatalyzed enantioselective carbon-chloride bond cleavage of hexachlorocyclohexanes (HCHs): Combined experimental investigation and theoretical calculations

Liang, Xu,Li, Minzhi,Mack, John,Lobb, Kevin,Zhu, Weihua

, p. 11470 - 11476 (2018/08/28)

Enantioselective electrocatalysis of α-, β-, γ- and δ-hexachlorocyclohexanes (HCHs) by tetrakis-pentafluorophenyl-Fe(iii)porphyrin is described. The first example of the combined use of electrochemical measurements and theoretical calculations to determine the mechanism of the enantioselective C-Cl bond cleavage of the electrocatalysis is reported. The electrochemical measurements demonstrate that the reactivity of the HCHs follows the order γ-HCH > α-HCH > δ-HCH > β-HCH. Steric considerations and a molecular orbital theory approach can be used to rationalize the enantioselective nature of the catalysis based on the ease of approach of each Cl atom to the central Fe(i) ion and a consideration of the nodes on the C-Cl bonds that weaken these bonds in a manner that results in bond cleavage and the formation of an Fe-Cl bond.

Paragraph 0051; 0052; 0053, (2017/04/03)

The invention belongs to the technical field of herbicide dicamba preparation and relates to a dicamba preparation process. The dicamba preparation process includes steps: taking benzene as a raw material to generate 1,2,4-trichlorobenzene through directional chlorination, catalysis, re-chlorination and rectification; hydrolyzing the 1,2,4-trichlorobenzene to generate a mixture of 2,5-dichlorophenol and 2,4-dichlorophenol, and separating and purifying to obtain 2,5-dichlorophenol; using the 2,5-dichlorophenol to prepare 3,6-dichlorosalicylic acid; subjecting the 3,6-dichlorosalicylic acid to methylation, saponification, acidification and the like to obtain dicamba. By optimization of technical steps and parameters, the whole dicamba preparation process has advantages of simplicity, low cost, high yield, high selectivity, remarkable reduction of wastewater and increase of equipment utilization rate.
