Abstract

The mineralogical class of organic compounds associated to hydrogen. Hydrogen, apparently, is the most abundant element present in the Universe, totalizing approximately 88.6 % of known atoms. It exhibits a geochemical abundance of 0.14 % in the Earth crust, occurring also in volcanic gases, aurora borealis, water, human body, hydrocarbons (petroleum, pit coal, peat, and bituminous shale), plants, animals, and a great number of minerals. This work is a contribution to the scientific knowledge of these substances and shows that hydrogen is present in the chemical composition of 40 from the 41 minerals of this interesting mineralogical class of organic compounds. Most of these compounds has significant importance in their corresponding industrial synthetics, mainly in the pharmaceutical and chemical industries. Substances such as oxalates, amides, formiates, acetates, fluorine, nickel-porphyrin, coronene, citrate, purine, dipertene, anthraquinone, phthalimide, mellate and phenanthrene, have multiple applications, such as electropolimerizating films, reagents for synthesis of organic compounds, plasticizers, inputs for the preparation of nanomaterials, separation and concentration of REE and transuranic elements, dietary nutrient supplements, water treatment reagents, coating of valves and additives in cosmetics, metallic paints and plastics in general
