ABSTRACT
Petroleum and natural gas are made up of hydrocarbon constituents, which are comprised of one or more carbon atoms, to which hydrogen atoms are attached. Petrochemical intermediates are generally produced by chemical conversion of primary petrochemicals to form more complicated derivative products. Specific examples of inorganic chemicals prepared from petrochemical sources are presented and included ammonia, hydrazine, hydrogen, nitric acid, sulfur, and sulfuric acid which are presented in alphabetical order rather than in any order of preference. Synthesis gas consists of a non-hydrocarbon mixture and hydrogen that is obtained from any one of several carbonaceous sources. There are several processes that are available for the production of hydrazine—the essential or step in each process is the creation of the nitrogen-nitrogen single bond. Hydrogen is the lightest known element, and is only found in the free state in trace amounts, but is widely spread in a combined form with other elements.
