Thermal fractionation of petroleum consumes large amounts of energy. Here stable microporous polymers are synthesized using click chemistry, which have similar performance to commercial polyimides for the fract
While this approach avoids many of the immediate hazards that bulk oil poses to marine and coastal ecosystems, it introduces the possibility of long-term effects resulting from the introduction of the complex and potential toxic components of petroleum into the ocean’s food chain. A number of ...
Kerosene contains alkanes from about 10 to 16 carbon atoms. Above n=17, the alkanes are solids at room temperature. Alkanes with higher values of n are found in diesel fuel, fuel oil, petroleum jelly, paraffin wax, motor oils, and for the highest values of n, asphalt. ...
Biomass-derived monomers, such as adipic acid (AA), 2,5-furandicarboxylic acid (FDCA), and 1,3-propanediol (PDO) can fully extend the boundaries of petroleum-based applications with desirable elastic properties, biodegradability, and impermeability. ...
Petroleum-based emollients such as petroleum jelly and mineral oil are found in many formulations because they do not contain double bonds or reactive functional groups. Silicone oils such as cyclomethicone, dimethicone are often added to increase slip and emolliency (See Figure 5). ...
candlesticks were presented to Queen Victoria in 1836. Sometimes called ‘vaseline glass’ because of the similar colouration of the petroleum jelly, the glass coloured with uranium dioxide has a strong yellow-green shade that is most dramatic in ultraviolet light, where it glows a conspicuous ...

22.5 Petroleum The refining process starts with the distillation of petroleum (crude oil) into fractions according to boiling point. Cracking is a controlled process by which hydrocarbons are broken down or rearranged into smaller, more useful molecules. ...
As a matrix, a retail-available petroleum jelly was used to simulate a real product cleanup. The TLC plates were analysed under an UV lamp (Camag, Muttenz, Switzerland) at 254 nm. Table 2. Test compounds for the TLC investigation. #SubstanceFunction 1 BHT Antioxidant 2 α-Tocopherol ...
11.The method of claim 7, wherein the each of the first and second compositions further comprise a base selected from the group consisting of white petrolatum, white petrolatum USP, mineral jelly, petroleum jelly, yellow petrolatum, yellow soft paraffin, white soft paraffin, fats, waxes, sterols...
