Water is the most abundant compound on the planet’s surface. Water exists naturally in a liquid, solid and gaseous form. The liquid phase of water is the most common. The solid phase usually takes the form of amalgamated crystals or loosely accumulated granular crystals. The gaseous phase or the vapour phase exists for temperatures above 100°C and is known as water vapour. It is possible, under certain conditions for water to exist in all three phases at one time, in a …show more content…
It is a colourless compound, highly flammable and is soluble in water. Pyridine can be harmful if it is inhaled, absorbed through the skin or swallowed. The chemical was first found in 1849 and is an important raw material in the modern chemical industry.
Some of the uses of Pyridine:
• A precursor to agrochemicals.
• It is a solvent and reagent.
• Added to ethanol, makes ethanol unsuitable for consumption by humans.
• Vitro synthesis of DNA
Pyridine can be found in the leaves and roots of Atropa belladonna, however, it is not naturally abundant. Small amounts of Pyridine can be found in everyday life in compounds that have been produced in a canning or roasting process.
Pyridine was historically extracted from coal tar, this method was not very sustainable. In modern times Pyridine can be produced synthetically using various name reactions such as Chichibabin synthesis.
The formation of acrolein from acetaldehyde. Condensation of pyridine from acrolein and acetaldehyde.
