	Hydrocarbon - Wikipedia, the free encyclopedia
		Hydrocarbons are mined from tar sands, oil shale and potentially extracted from sedimentary methane hydrates.
		Hydrocarbons are of prime economic importance because they encompass the constituents of the major fossil fuels (coal, petroleum, natural gas, etc.) and plastics, paraffin, waxes, solvents and oils.
		Hydrocarbons (usually coal) are burnt and the energy released in this way is used to turn water in to steam, which is used to turn a turbine that generates energy.

	Hydrocarbon Ingestion \| Poison Control Center - Children's Hospital of Philadelphia
		In fact, petroleum distillate refers to a type of hydrocarbon which results from the processing of crude oil, and may be aliphatic or aromatic.
		When considering hydrocarbons and the nature of their effects, it is important to remember that these substances may also be vehicles for highly toxic ingredients such as camphor, heavy metals and organophosphate insecticides.
		Symptoms of aliphatic hydrocarbon ingestion, in the absence of toxic substituents, are confined to the gastrointestinal tract and the respiratory tract.

	Aromatic hydrocarbon - Wikipedia, the free encyclopedia
		is a hydrocarbon, the molecular structure of which incorporates one or more planar sets of six carbon atoms that are connected by delocalised electrons numbering the same as if they consisted of alternating single and double covalent bonds.
		The term 'aromatic' was assigned before the physical mechanism determining aromaticity was discovered, and was derived from the fact that many of the compounds have a sweet scent.
		The configuration of six carbon atoms in aromatic compounds is known as a benzene ring, after the simplest possible aromatic hydrocarbon, benzene.

		Hydrocarbons can be classified as being aliphatic, in which the carbon moieties are arranged in a linear or branched chain, or aromatic, in which the carbon moieties are arranged in a ring.
		Halogenated hydrocarbons are a subgroup of aromatic hydrocarbons, in which one of the hydrogen molecules is substituted by a halogen group.
		The chemical properties of the individual hydrocarbon determine the specific toxicity, while the dose and route of ingestion affect which organs are exposed to the toxicity.

	Hydrocarbon Resins Market Study Report - European Adhesives Industry
		Hydrocarbon resins, as is the case for all tackifiers, are mostly used in adhesives as modifiers for polymers that have been selected for the specific end use purpose.
		The use of hydrocarbon resins has historically developed in substitution for natural product-sourced resins such as rosin derivatives or polyterpenes during times of short supply.
		With the development of hydrocarbon resins with lighter colors, better compatibility, enhanced tack with specific elastomers, improved specific adhesion to various substrates, and a broader range of melt points, hydrocarbon resins have now established their own presence.

		In emissions research, hydrocarbon speciation is a powerful tool used to understand the combustion process and to observe the effects of varying gasoline and alternate fuel composition, fuel additives, and emission control hardware.
		Analysis of the heavy hydrocarbons from diesel exhaust is performed with an automated thermal sample desorption system coupled to a gas chromatograph/quadrupole mass spectrometer (GC/MS) and a flame ionization detector (FID).
		Hydrocarbon speciation data generated by SwRI helped establish California’s Phase II gasoline requirements and were used in the development of the EPA complex model.

		While the aliphatic hydrocarbons have little GI absorption, aspiration frequently occurs, either initially, or in a semidelayed fashion as the patient coughs or vomits, thereby resulting in pulmonary effects.Once aspirated, the hydrocarbons can create a severe pneumonitis.
		Hydrocarbon pneumonitis results from a direct toxic affect by the hydrocarbon on the lung parenchyma.
		Many of the hydrocarbons that affect the CNS directly are able to make their way across the blood-brain barrier because certain hydrocarbons are highly lipophilic.

	Hydrocarbon "metabolism"
		In this paper, we consider the "intermediary metabolism" of a hydrocarbon assembler, i.e., the set of reactions that permit processing of the feedstock molecules and their conversion into molecular tools (positionally controlled carbenes, radicals, and other reactive species).
		The stiff hydrocarbons include a wide enough class of materials to be a very attractive goal (diamond, graphite, and structurally related materials are included in this class).
		As the radical will have to approach the butadiyne quite closely during the radical addition, and as the hydrocarbon structure confining the butadiyne will also have to be in close proximity to the butadiyne, allowing close proximity between the silicon radical and the confining structure relaxes a significant design constraint.
