Do you know the sources of organic compounds?

Feb 23, 2016


   Do you know the sources of organic compounds?And are you interested in sources of organic compounds?Now let'slearn something about sources of organic compounds.

   The earliest sources of organic compounds in the world
   A.
The idea that the organic molecule on the object is born to the earth when it is struck by an alien planet. And the process of organic matter on the object is roughly the same as the following two mechanisms.

   B.
Earth's oxygen, nitrogen, hydrogen, carbon and other elements in the sun's ultraviolet rays and the role of storm, the formation of a protein, and it is a coincidence that the earth is good at a distance from the sun, so there is a life. In the next life is constrained by the environment and further evolution. And then after several billion years of evolution, human beings have.

   C.
Billions of years ago, the earth's climate was much less oxygen than it is now, and the temperature of the mushrooms that erupted when the volcano erupted is about 200 degrees Celsius. These substances fall to the ground, and after many years of interaction, they can be synthesized with self replicating RNA molecules, so that it makes the emergence of the original cells possibally.

   The sources of organic compounds pollutions include phenols, aldehydes, sugars, polysaccharides, protein and oil, a large presence in many industrial wastewater. Organic toxic pollutants mainly have the following categories:

(1) organic pesticides can be divided into the organic phosphorus pesticide and the organic chlorine pesticide. Toxicity of organic phosphorus pesticide, although large, but generally susceptible to degradation, accumulation is not strong, and impact on the ecosystem is not obvious; and the vast majority of organochlorine pesticides, toxicity, almost no degradation and accumulation is very high,the ecological system has significantly affected.

(2) carcinogenic substances. Carcinogens can be generally divided into three categories: polycyclic aromatic hydrocarbons (PAHs), such as 3,4 - benzopyrene, etc.; heterocyclic compounds, such as aflatoxin; aromatic amines, such as acetanilide, benzidine and other.

(3) general organic matter. If there are more than 2000 kinds of phenolic compounds, the most simple is the phenol, are highly toxic substances; cyanide compounds are toxic, in which the environmental impact of acrylonitrile is the most eye-catching. (4) oil pollutants. Petroleum is a mixture of alkanes, olefins and aromatic hydrocarbons.
