in Bucharest and co-authored a monograph on the physical and technical properties of Romanian crude oil.
His most significant invention, was the
aromatic hydrocarbons (benzene, toluene, xylene, etc.). The procedure was first applied experimentally in Romania at the Vega Refinery and later spread to France (notably Rouen), Germany
, and subsequently throughout the world.
Research and business in Germany
In 1910, Edeleanu settled in Germany where he founded a company called "Allgemeine Gesellschaft für Chemische Industrie". Due to the success of the name "Edeleanu", the company changed its name to Edeleanu GmbH in 1930. During the

trust. The name Edeleanu is still used for the refinery department until this day.
Edeleanu returned to Romania, where he died in Bucharest in April 1941.
Heritage
By 1960, there were 80 Edeleanu facilities worldwide. The Edeleanu Method is still used today, in its many variations, and remains the basic process for manufacturing high quality oils.
Edeleanu obtained 212 patents for inventions in Romania, the United States, Germany, France, Austria, Sweden, and Holland.
