Get PriceUltrafine particles (UFPs) are particulate matter of nanoscale size (less than μm or 100 nm in diameter) Regulations do not exist for this size class of ambient air pollution particles which are far smaller than the regulated PM 10 and PM particle classes and are believed to have several more aggressive health implications than those classes of larger particulates

Get PriceParaffin hydrocarbon also called alkane any of the saturated hydrocarbons having the general formula C n H 2n 2 C being a carbon atom H a hydrogen atom and n an integer The paraffins are major constituents of natural gas and containing fewer than 5 carbon atoms per molecule are usually gaseous at room temperature those having 5 to 15 carbon atoms are usually liquids
Get PriceParaffins occur as simple straight or branched polymeric chains of hydrocarbons of alkanes with a chemical composition of C n H 2n 2 Paraffin wax was first commercially produced in 1867 by the chilling of petroleum to result in the precipitation of paraffin wax Nowadays paraffin wax is obtained from petroleum by the dewaxing of light lubricating oil stocks Synthetic paraffin has been

Get PriceParaffin wax is mostly found as a white odorless tasteless waxy solid with a typical melting point between about 46 and 68 °C (115 and 154 °F) and a density of around 900 kg/m 3 It is insoluble in water but soluble in ether benzene and certain esters Paraffin is unaffected by most common chemical reagents but burns readily
