Is M dinitrobenzene a solid?
Dinitrobenzene is a pale yellow or white crystalline (sand- like) solid which is usually a mixture of three isomers. It is used in making dyes, other chemicals, and explosives. * Dinitrobenzene is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP, IRIS, NFPA and EPA.
Is M dinitrobenzene soluble in alcohol?
Soluble in benzene, chloroform, ethyl, alcohol-soluble slightly soluble in water.
What is dinitrobenzene test?
1. m-dinitrobenzene Test. Ketones react with m-dinitrobenzene to give a violet colouration.
What is the color of M-dinitrobenzene?
yellow
1,3-Dinitrobenzene
| PubChem CID | 7452 |
|---|---|
| Description | 1,3-dinitrobenzene is a dinitrobenzene that is benzene disubstituted at positions 1 and 3 with nitro groups. It has a role as a neurotoxin. ChEBI M-dinitrobenzene is a yellow solid with a slight odor. Sinks in water. (USCG, 1999) CAMEO Chemicals |
What is the Colour of nitrobenzene?
Nitrobenzene appears as a pale yellow to dark brown liquid.
How do you make M dinitrobenzene?
12.5 ml (15 g) of nitrobenzene in portions of about 3 ml is added slowly and after each addition the flask is shaken thoroughly. The mixture is heated on water bath for 30 min. with shaking. Then it is allowed to cool and poured into about 500 ml of cold water cautiously with vigorous stirring.
How meta dinitrobenzene is formed?
1,3-Dinitrobenzene is accessible by nitration of nitrobenzene. The reaction proceeds under acid catalysis using sulfuric acid. The directing effect of the nitro group of nitrobenzene leads to 93% of the product resulting from nitration at the meta-position.
Is Meta a dinitrobenzene?
1,3-dinitrobenzene is a dinitrobenzene that is benzene disubstituted at positions 1 and 3 with nitro groups. It has a role as a neurotoxin.
Which is the chemical formula for dinitrobenzene?
The three possible arrangements of the nitro groups afford three isomers, 1,2-dinitrobenzene, 1,3-dinitrobenzene, and 1,4-dinitrobenzene. Each isomer has the chemical formula C 6 H 4 N 2 O 4 and a molar mass of about 168.11 g/mol. 1,3-Dinitrobenzene is the most common isomer and it is used in the manufacture of explosives .
What happens if you mix dinitrobenzene with tetranitromethane?
Mixture of 1,3-dinitrobenzene with tetranitromethane was found highly explosive [Urbanski, 1964, vol. 1, 592]. 1,2-dinitrobenzene is a severe explosion hazard when shocked or exposed to heat or flame. When heated to decomposition all dinitrobenzens emit toxic fumes of nitrogen oxides [Sax, 9th ed., 1996, p. 1374].
What does nitrobenzene mean in terms of meta position?
It mean electron density is low on both position (artho, Pera). So, the next electrophile will attack on meta position. So, nitrobenzene is called meta directing.
What is the melting point of m-dinitrobenzene?
Melting Point: 194 ° F (NTP, 1992) Vapor Pressure: data unavailable Vapor Density (Relative to Air): data unavailable Specific Gravity: 1.58 at 64.4 ° F (USCG, 1999)
