Petroleum paraffins

Mineral/ Petroleum Paraffin Mixtures of straight chain alkanes... 

Paraffin is a name that is commonly used to denote a group of saturated alkane hydrocarbons with the general formula Q,H2 +2, n being greater than 20. They take both solid and liquid forms. The solid form known as paraffin wax was discovered by Karl Reichenbach in 1830. Paraffins are mostly obtained from petroleum. Paraffin oil, used as a fuel, is also known as kerosene. 

Hydrogenation of carbon oxides with iron, cobalt, or nickel catalysts (Fischer-Tropsch process). Hydrocarbons are the main products Recovery and separation of oxygenated products obtained from CO and H2 Partial oxidation of nonaromatic hydrocarbon mixtures, e.g., petroleum, paraffins, and natural gas, to produce a mixture of products, such as esters, acids, aldehydes, ketones, and alcohols. This also includes higher fatty acids from petroleum and patents on formaldehyde production...

Waxes Waxes are an additional class of materials used to improve rubber ozone protection primarily under static conditions. Waxes used in elastomeric formulations fall into two categories microcrystalline and paraffin. Microcrystalline wax has a melting point in the range of 55-100 C and is extracted from residual heavy lube stock of refined petroleum. Paraffin wax has melting points in the range of 35-75°C and is obtained from the light lube distillate of crude oil. 

Paraffin wax n. Inert hydrocarbon wax derivative of crude petroleum. Paraffin waxes are distinguished by their melting points. Their main uses include the conferring of water resistance, slip, or solvent retention in special types of compositions. 

Oxidation Products of Petroleum Paraffin 2.2.1 Brief Introduction to Synthetic Fatty Acids... 

Oxidized paraffin soaps can be synthesized by adopting petroleum paraffin as raw material. Because synthetic reaction of oxidized paraffin is relatively simple, oxidized paraffins are widely applied in industry. Synthetic methods of oxidized paraffin comprise air oxidation process and NO2 oxidation process. Air oxidation process is widely applied. In general, petroleum paraffin is heated to 150 or above in the presence of O2 and KMn04. The oxidation reactions can be given by ffie following ... 

As mentioned before, the collecting capability of hydroxy acid is better than that of general fatty acid. Petroleum ether extracted from oxidized petroleum paraffin... 

Therefore, the deep oxidation of petroleum paraffin is needed for improving the collecting capability of oxidized paraffin soap product. But it should be pointed out that the collecting capability of oxidized paraffin soap will decrease when the oxidation of petroleum paraffin is too deep. The reason lies in that the molecular weight decreases with the increase in the oxidation degree of petroleum. And the decrease in molecular weight of reagent is bad for flotation performance of oxidized paraffin soap. 

Extrusion. Polychloroprene has been employed in a wide variety of extrusion (qv) processes. Intricate cross-sections such as highway compression seals, bulb weather-stripping, and hose represent a few examples. As with calendering, extrusion is very sensitive to nerve. The DuPont Dow neoprene sol/gel blend types are best suited for extrusion applications. Use of low levels of highly structmed furnace carbon blacks, stearic acid, petroleum, paraffin wax, triethanolamine benzoic acid, and calciiun stearate are particularly effective extrusion aids. The screw of the extruder should have a constant diameter root with increasing pitch. Heat history of the compound should be minimized, with only a brief warm-up before extrusion begins. The barrel and screw should be lun cool, 50°C, and the die hot, 95°C (96,119).
