Synthesis of Caffeine
Caffeine is prepared by following the points added below,
- Caffeine is a methylxanthine alkaloid that occurs naturally in the seeds, leaves, and fruit of several plants and trees native to Africa, East Asia, and South America.
- It can be synthesized by the reaction between dimethylurea and malonic acid.
- It can also be produced when theobromine is treated with methyl iodide and sodium methoxide.
- When uric acid is treated with methyl iodide in an alkaline solution, it produces 1,3,7-trimethyluric acid. On heating this further with phosphoryl chloride (POCl3), it produces chlorocaffeine, which forms caffeine on further reduction with hydrogen iodide.
- Caffeine is produced as a by-product in the manufacture of decaffeinated coffee by decaffeination. In the process of decaffeination, caffeine and decaffeinated coffee are produced by extracting caffeine from its natural sources, like coffee.
Caffeine Chemical Formula
Caffeine is a purine alkaloid and a trimethyl xanthine that acts as a stimulant for the Central Nervous System (CNS). Its chemical formula is C8H10N4O2 and is also termed methyl theobromine, 1,3,7-Trimethylxanthine, 7-methyltheophylline, guaranine, or theine.
Caffeine is an odorless white crystalline purine and has a bitter taste. Caffeine is a methylxanthine alkaloid that occurs naturally in the seeds, leaves, and fruit of several plants and trees native to Africa, East Asia, and South America. It can be synthesized by the reaction between dimethylurea and malonic acid. Caffeine is derived naturally from purine xanthine, which is present in more than sixty plants, including coffee, tea, and cocoa. It is the most often-used psychoactive substance worldwide. There are both positive and negative health impacts of caffeine. After repeated daily use, caffeine can cause a moderate form of drug dependence. So, when an individual stops using it after repeated use, it results in symptoms like sleepiness, headaches, and irritability.
