Chloropyrilene Chemical Properties,Usage,Production

Definition

ChEBI: Chloropyrilene is a dialkylarylamine and a tertiary amino compound.

General Description

Colorless liquid.

Air & Water Reactions

Slightly water soluble .

Reactivity Profile

A base. An organosulfide and an amine. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Fire Hazard

Flash point data for Chloropyrilene are not available, but Chloropyrilene is probably combustible.

Synthesis

Chlorothen is synthesized by condensation of 5- chloro-2-thienylchloride and N,N-dimethyl-N_x0002_- (2-pyridinyl)ethylenediamine in the presence of sodium or potassium amide .
