So with the long list of hydrocarbons -- gaseous, liquid, and solid -- called paraffins, that are obtained from petroleum and that are all composed of hydrogen and carbon, but with a different number of atoms of each, like a different number of a's or b's or c's in a word. ❋ John Burroughs (1879)
These hydrocarbons are known to chemists as "paraffins," ❋ W. J. Atkinson Butterfield (N/A)
Late last year, the agency quietly said that it would review the safety of phthalates, long-chain perfluorinated chemicals (PFCs), polybrominated diphenyl ethers (PBDEs) and short-chain chlorinated paraffins. ❋ Unknown (2010)
"The project will also result in increased production of medium waxes, mostly used for the candle industry in southern Africa, as well as liquid paraffins used in a variety of industrial applications." ❋ Unknown (2008)
Deasphalting also removes some sulfur and nitrogen compounds, metals, carbon residues, and paraffins from the feedstock. ❋ Unknown (2008)
There are basically four kinds of "reactive organics" that are important in smog photochemistry: paraffins, olefins, aromatics, and carbonyl compounds aldehydes and ketones, the latter being more commonly formed in the smog process than emitted outright. ❋ James Killus (2008)
I'm taking a bit of a liberty here by omitting alcohols, ethers, and other oxygenated compounds, partly because, ethanol and MTBE notwithstanding, they still don't amount to a large fraction of the mix, and partly because their photochemistry is pretty close to that of paraffins, or ketones that don't photolyze, i.e. break up by the direct action of sunlight. ❋ James Killus (2008)
The early days of smog chemistry were dominated by research into the chemistry of paraffins and olefins, so much so, in fact, that it wasn't until the mid-1970s that researchers realized that the photolysis of aldehydes and ketones was the primary source of catalytic radicals in the smog formation process. ❋ James Killus (2008)
The branched-chain (isomer) paraffins are usually found in heavier fractions of crude oil and have higher octane numbers than normal paraffins. ❋ Unknown (2007)
These compounds are more reactive than paraffins or naphthenes and readily combine with other elements such as hydrogen, chlorine, and bromine. ❋ Unknown (2007)
In China, for example, the mix of organic compounds is 46 percent paraffins, 32 percent olefins, 21 percent aromatics, and 1 percent aldehydes (Piccot, Watson, and Jones, 1992). ❋ Unknown (2000)
The plant also produces phenol and various types of cresols, as well as ammonia and ammonium compounds, solvents, creosote, methanol, paraffins, pipeline gas and sulphur. ❋ Unknown (1996)
On the other hand, a plant producing 100,000 tons of SCP from paraffins would require an equal supply of substrate and should thus be associated with an oil refinery having a minimal capacity of about 3 to 5 million tons of crude oil per year. ❋ Unknown (1983)
As in the case of SCP production from paraffins and methanol, optimal use of such sophisticated technology would require a minimal production well over the potential market of most developing countries, and would result in high investment and operation costs. ❋ Unknown (1983)
In addition, some of the large-scale industrial SCP processes developed over the past ten years use yeasts that utilize hydrocarbons (i.e., paraffins) as an energy source and carbon and hydrogen for growth and synthesis of cell constituents. ❋ Unknown (1979)
As in the case of SCP production from paraffins or methanol, the optimization of such sophisticated technology would require a minimal production of well over the potential market of most developing countries, and would result in high investment and operation costs. ❋ Unknown (1979)
During the nutritional evaluation of yeast grown on e-paraffins or gas oil, an experiment was carried out in which chicks were fed semi-synthetic diets with fishmeal or Yeast, respectively, as the sole source of protein. ❋ Unknown (1979)
Experimentation for several seasons has resulted in the finding that raw pine gum is miscible with the paraffins in almost all proportions because of physical or chemical affinity. ❋ Unknown (N/A)
I do not say tar, but more concentrated fuels, such as crude naphthas, paraffins, and pitch oil. ❋ Various (N/A)
I gave the old [paraffin] a [fiver] to get himself some [booze]. ❋ Jonny Bastard (2020)
After getting [white girl wasted] paul went [paraffin] teabagging to turn [Christy] on. ❋ Dick-fingers (2017)
