PETROLEUM


PETROLEUM


1 Oil of Inorganic Materials

Stated by Berthelot. He said the metal - alkali metals react with CO2 in the earth at high temperatures to form acetylene gas (C2H2), which later formed the other hydrocarbon compounds.

Another hypothesis by Dmitri Mendeleev Ivaovick, iron carbide in the Earth react with water and produce acetylene gas. This reaction is similar to the reaction that occurs between a rock carbide and water.

2 Crude Oil from Organic Matter

This theory stated by o.g. Macquir, based on the source of coal which is also derived from plants - plants.

As for the theory that oil comes from animals, first proposed by JPLesley. Then another scientist named B. Haquet petroleum distillation experiment of mollusks. Another experiment conducted by H. Hofer and C.Eugler. They do a distillation of the clam meat and fish at a temperature of 3000C - 4000C and a pressure of 10 atm. In substance produced substances resembling petroleum.

Based on the theory of creation, the oil derived from the weathering of living organisms that lasts very long (millions - millions of years). Petroleum formation requires an environment that can provide high levels of organic matter and allow preservation so that no oxidation or spoilage. The beach area has a river estuary facing the open sea, are more likely to produce organic matter. Furthermore, the organic matter is spread into a smooth slab of shale rock, accumulated and concentrated. Furthermore, it moved into the rocks and trapped in sedimentary rocks.

OIL COMPONENTS
1 Straight Chain Aliphatic Hydrocarbon Compounds

Also called normal alkanes or paraffin. These compounds are widely available in natural gas and oil, which has a short carbon chain

2 Forms of Cyclic Hydrocarbons Compounds

Cyclic hydrocarbons are hydrocarbons or cycloparaffins cycloalkane group. Hydrocarbon compounds have the same molecular formula alkenes, but has no double bond and form a ring structure. In general, cyclic hydrocarbons in petroleum a mixture of cyclopentane and cyclohexane called naften. In petroleum, the intermolecular cyclic sometimes - sometimes combine to form a molecule that consists of several cyclic compounds.

3 Compounds Aliphatic Hydrocarbon Chain Branching

Example: isoalkana or isoparaffins

Amount of hydrocarbons is not as straight-chain aliphatic hydrocarbons and cyclic hydrocarbons form.

4 Compound Aromatic Hydrocarbons

Is a cyclic hydrocarbon compounds that form hexagons, doubly bonded hose - alternating, and unsaturated hydrocarbons. Amount of hydrocarbons is at least among the other types. In general, these aromatic hydrocarbons found in petroleum that has a large number of C atoms






Crude oil (crude oil) is mostly composed of compounds of saturated hydrocarbons (alkanes). The unsaturated hydrocarbons (alkenes, alkynes and alkadiena) very little dkandung by oil, because susceptible addition to alkanes.

Because petroleum berasl of fossil organisms, mak oil containing sulfur compounds (0.1 to 7%), nitrogen (0.01 to 0.9%), oxygen (0.6-0.4%) and metal compounds in amounts smaller sanagt. Crude oil is separated into a number of fractions through a distillation process (distillation).

Separation of crude oil into the pure components (single compound) is not possible and also not prakstis because too many compounds present in the oil and hydrocarbons have isomers with close boiling points. Fractions obtained from the distillation of crude oil is a mixture of hydrocarbons that boil at a certain temperature trajectory. For example, the fraction of kerosene (kerosene) is composed of a mixture of compounds boiling between 180 0 C-250 0 C. Distillation process is done by using a distillation column or tower.

  1. because Alkanes are the main raw materials for the manufacture of organic compounds other.
    2. Alkanes trading system is the basis of the name - the name of all organic compounds.

    Alkanes are hydrocarbons that all bonds saturated. / Single. Alkanes also called paraffin series of significant affinity smaller and less reactive.
