In 1834 German chemist Eilhardt Mitscherlich heated benzoic acid with lime and produced benzene. As a result, there are strict controls on benzene emissions. In 1858 he showed that carbon can link with itself to form long chains. Then, Mendeleev later reported, "In a dream I saw a table where all the elements fell into place as required. This graphic looks at his structure and its limitations and shows how later work improved upon his initial proposal. He had christened it as "bicarburet of hydrogen." However, Eilhard Mitscherlich was the scientist who named it benzene in 1833. Kekule', a German chemist once slept during his work and saw the atoms in his dreams dancing and moving randomly.
