Biography of Adolf von Baeyer - Chemists

Johann Friedrich Wilhelm Adolf von Baeyer was born on October 31, 1835, in Berlin, Germany. Baeyer a German chemist, was recognized in 1905 for his work on organic dyes and compound substances hidroaromatik. Initially, he studied at Humboldt University in Berlin, Baeyer studied mathematics and physics. However, he soon discovered his love of the chemical and moved to Heidelberg to study with Robert Bunsen in 1856. Bunsen was the famous chemist, who are well known for perfecting the burner. Baeyer's father a Prussian general. His mother was Jewish. Although the father held the rank of general interest Baeyer big hello to science. Baeyer apparently inherited his father. He msuk Heidelberg University majoring in chemistry. In Heidelberg, studied in the laboratory Baeyer August Kekulé, renowned organic chemist. 

Professor named Bunsen and Kekulé. Bunsen emphasized the importance of experimentation and research, emphasizing the importance of the theory of Kekulé. Baeyer combine the two. In 1858, Baeyer received his doctorate in chemistry from the University of Berlin. In 1871, he became a professor in Strasbourg and in 1875, Baeyer became Professor of Chemistry at the University of Munich. He was also awarded the Davie Medal by the Royal Society of London in 1881, for his work with indigo. He received the Nobel Prize for chemistry (1905) for discovering artificial dyes, especially indigo synthesis (1880), and acidic barbiturates (sleeping pills ingredients to make). He also found the chemical structure of indigo (1883).

Perhaps our readers have heard of "Indigo", plants of India. The word Indigo is a Spanish word that means India. In Indonesia indogo called toms or Tarum. Of this plant is made of blue dye called indigo, which is used to dye batik cloth. The Egyptians have been using indigo since 2000 BC. When the British seized India, indigo was brought to England to dye cotton, wool, and clothes of the sailors. But that comes from the indigo plant is very expensive and poorly mjutunya.

When there was war in Europe, the owners of the textile industry can not obtain indigo. Baeyer then seek immediate sense. He wants to make indigo synthesis. Synthesis of man-made means. He began working in 1865. He worked hard for 15 years. In 1880 he managed to find a synthesis of indigo. Three years later (1883) he managed to find indogo chemical structure, since then the German chemist sitesis competing to make the other dye, followed Baeyer. Prior to World War 1 (1914-1918), Germany became the largest producer of dyes in the world.

In addition to mixing the indigo dye, a few other achievements include the discovery Baeyer ptanein dyes, observation poliasetilen, oxonium salts, uric acid and derivatives. Bayer barbituik acid together in 1864. This acid is used in surgery as a sedative or hypnotic. Baeyer also famous for his work in theoretical chemistry, developed the theory of 'saturation' (Spannung) on the triple bond and saturated theory in small carbon rings. Is also the founder Baeyer Baeyer Chemical Co.. Adolf von Baeyer died on August 20, 1917 in Starnberg.
