The pyridine is a chemical Composé aromatic of empirical formula, easily flammable and harmful by inhalation, contact with the skin and ingestion. SPALLING HAMMERS: C1=NC=CC=C1
The pyridine is a limpid liquid with an unpleasant odor (sour, putrid and evoking fish). Benzene, with one CH group in the six-membered boxing ring replaced by has Nitrogen atom. Pyridine is obtained from crude Coal tar gold is synthesized from Acetaldehyde and Ammonia. -->
The pyridine has an equatorial free doublet on the nitrogen atom which does not take part in the aromatic system π. Consequently, the pyridine is a bases whose chemical properties are similar to those of the tertiary amines. The pyridine can be protonic by reaction with acid and forms a aromatic Cation then called pyridinium.
The pyridine is often used like Solvant and Réactif in organic synthesis. It is also a Précurseur for the synthesis of intermediate products used in manufacture of insecticides, weedkillers, drugs, food flavorings, dyes, adhesives, paintings, explosives and of disinfecting. The pyridine is also used to denature alcohol, antifreezes and fungicides, like like additive for the textile dyeings.
The pyridine is dangereous because of inhalation, ingestion or skin absorption. It can cause a reduction of the male fertility and is regarded as carcinogen. The usual symptoms of one exposure to pyridine are: headaches, cough, breathing of the asthmatiquee type, laryngitis, nauseas and vomiting.
even Lone off Electron S At the nitrogen atom that does not participate in the aromatic pi-system. This makes pyridine has BASIC compound with chemical properties similar to Tertiary amine S. Pyridine is protonated by reaction with Acid S and forms has positively charged aromatic Polyatomic ion called Pyridinium Cation.
Pyridine is widely used ace has Solvent and Reagent in Organic chemistry and it is also has starting material in the synthesis off compounds used aces year intermediate in making insecticidal, weedkillers, pharmaceuticals, food Flavoring S, Dye S, Rubber chemicals, Adhesive S, Paint S, Explosive S and Disinfectant S. Pyridine is also used ace has denaturing agent for Antifreeze mixtures, for Ethyl alcohol, and for Fungicide S, and aces has Dyeing aid for textile.
Pyridine has harmful substance yew inhaled, ingested gold absorbed through skin, it is known to reduce male fertility and is considered Carcinogenic ace well. Common symptoms off exposure to pyridine include: headache, coughing, asthmatic breathing, Laryngitis, nausea and vomiting. -->
