Propene, also known as propylene or methyl ethylene, is an unsaturated organic compound having the chemical formula C3H6. It has one double bond, and is the second simplest member of the alkene class of hydrocarbons.
Detailed description
Properties
At room temperature and atmospheric pressure, propene is a gas, and as with many other alkenes, it is colorless and has a faint petroleum-like odor.[2]
Propene has a higher density and boiling point than ethylene due to its greater mass. It has a slightly lower boiling point than propane and is thus more volatile. It lacks strongly polar bonds, yet the molecule has a small dipole moment due to its reduced symmetry (its point group is Cs).
Propene has the same empirical formula as cyclopropane but their atoms are connected in different ways, making these molecules structural isomers.
Occurrence in nature
Propene is found in nature as a byproduct of vegetation and fermentation processes.
On September 30, 2013 NASA announced that the Cassini orbiter space craft, part of the Cassini-Huygens mission, had discovered small amounts of naturally occurring propene in the atmosphere of Titan using spectroscopy.
Uses
Propene is the second most important starting product in the petrochemical industry after ethylene. It is the raw material for a wide variety of products. Manufacturers of the plastic polypropylene account for nearly two thirds of all demand.[11] Polypropylene end uses include films, fibers, containers, packaging, and caps and closures. Propene is also used for the production of important chemicals such as propylene oxide, acrylonitrile, cumene, butyraldehyde, and acrylic acid. In the year 2013 about 85 million tonnes of propene were processed worldwide.[11]
Propene and benzene are converted to acetone and phenol via the cumene process. Propene is also used to produce isopropanol (propan-2-ol), acrylonitrile, propylene oxide and epichlorohydrin.[12] The current industrial production of acrylic acid involves the catalytic partial oxidation of propene.[13] The propene is also an intermediate in the one-step propane selective oxidation to acrylic acid.[14][15][16][17] In industry and workshops, propene is used as an alternative fuel to acetylene in Oxy-fuel welding and cutting, brazing and heating of metal for the purpose of bending. It has become a standard in BernzOmatic products and others in MAPP substitutes,[18] now that true MAPP gas is no longer available.
Reactions
Propene resembles other alkenes in that it undergoes addition reactions relatively easily at room temperature. The relative weakness of its double bond explains its tendency to react with substances that can achieve this transformation. Alkene reactions include: 1) polymerization, 2) oxidation, 3) halogenation and hydrohalogenation, 4) alkylation, 5) hydration, 6) oligomerization, and 7) hydroformylation.

Packaging details
We usually bag ores in 50kg,100kg,150kg and 200kgs depending on specifications. Now for a 50kg bagged ore it will contain 480 bags for a 20ft container,610 bags for a 40ft container,  642 and 674 bags for a 48ft and 53ft containers respectively. For a 100kg bagged ore we  have 240 bags for a 20ft container, 305 bags for a 40ft container,329 bags for  48ft  and 344 bags for a 53ft container. However, the best method to transport ores such as iron is through ship loads such as in 25000 ,50000, tones and so on, because through this way the transporting is less cumbersome and one can transport more materials at a given time.

PRICE
$1184.28/KG OR $538.30/IB
