Raw materials And Preparation Products

Hazard Information

General Description

A dark green crystalline solid. Insoluble in water. Harmful if ingested.

Reactivity Profile

P-NITROSODIMETHYLANILINE(138-89-6) has a delayed violent reaction with acetic anhydride.

Air & Water Reactions

Susceptible to spontaneous combustion upon exposure to air. Insoluble in water.

Health Hazard

Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.

Fire Hazard

Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.

Chemical Properties

green crystalline powder

Uses

manufacture of organic Compounds; accelerator in vulcanizing; in printing fabrics.

Definition

ChEBI: The 4-nitroso derivative of N,N-dimethylaniline.

Purification Methods

Recrystallise the nitroso-aniline from pet ether or CHCl3/CCl4 and dry it in air. Alternatively suspend it in H2O, heat to boiling and add HCl until it dissolves. Filter, cool and collect the hydrochloride [42344-05-8] with m 177o after recrystallisation from H2O containing a small amount of HCl. The hydrochloride (e.g. 30g) is made into a paste with H2O (100mL) in a separating funnel. Add cold aqueous 2.5 NaOH or Na2CO3 to a pH of ~ 8.0 (green color due to the free base) and extract with toluene, CHCl3 or Et2O. Dry the extract (K2CO3), filter, distil off the solvent, cool the residue and collect the crystalline free base. Recrystallise it as above and dry it in air. [Beilstein 12 IV 1558.]
