Category : Dyestuffs and Pigments
CAS NO : 97-00-7 EC NO : 202-551-4 MF : C6H3ClN2O4 MW : 202.552 Specification : 99% min Packing : 25kg 50kg drum or bag Product description : What is the chemical of 2,4-Dinitrochlorobenzene ? Appearance: Light yellow or yellow brown needle shaped crystals with a bitter almond aroma ; Assay: 99% min by HPLC ; IR Identity: conform to standard ; HNMR： conform to standard ; carbon spectrum: conform to standard ; Water by K. F.:0.5% max or as per the customer’s request ; Loss on drying:0.5% max. or as per the customer’s request ; Melting point: 48-50 °C; =============================================================================== Widely used in the synthesis of dyes (such as sulfur blue 3R, sulfur black BRN, etc.), pesticides (such as pesticide dinitrogen powder), and pharmaceuticals (such as picric acid, p-nitroaminophenol, and other intermediates). In addition, it can also be used as an analytical reagent for identifying pyridine compounds such as niacin and nicotinamide, as well as thiol compounds, and applied in organic microanalysis and molecular type inhibitors. Mainly used as raw materials for dyes, pesticides, pharmaceuticals, etc. Used for manufacturing sulfurized dyes such as sulfurized deep blue 3R, sulfurized black BRN, RN, B2RN, BN, etc. This product is also a raw material for intermediates such as dinitrophenol, dinitroaniline, picric acid, and p-nitroaminophenol. It can also be used to manufacture saccharin, pesticide dinitrogen powder, etc. Use for testing niacin, nicotinamide, and other pyridine compounds. Detecting thiols in thiol compounds. Organic microanalysis is a standard for determining carbon, hydrogen, and chlorine. organic synthesis ============================================================================== Production method 1. Obtained by nitration of chlorobenzene twice with mixed acid. The two nitrification processes have achieved continuous production, and the production equipment mainly consists of four reaction towers. Mix acid (nitric acid accounts for 33.1%, sulfuric acid accounts for 62.88%, and the rest is water) at a flow rate of 11.3 kg/min and chlorobenzene at a flow rate of 3.18 kg/min through four reaction towers, with reaction temperatures controlled at 75-85 ℃, 100 ℃, 120 ± 20 ℃, and 125 ± 2 ℃, respectively. After about 3 hours of reaction, the reaction product is washed with water to obtain qualified products. 2. After nitration with mixed acid, separation of waste acid, neutralization, water washing, and crystallization purification of the by-product co melted oil of para - and ortho nitrochlorobenzenes, the finished product is obtained, and 2,6-oil is produced as a byproduct.
