	Polymerization process for cis-1,4-polybutadiene using cycloalkane solvents and an aromatic polymerization regulator - ...
		It was unexpectedly found that when a cycloalkane was used as the chief solvent in the polymerization of butadiene, the polymerization proceeded at too fast a rate as a result of which it was difficult to control the polymerization temperature.
		Thus the present invention is an improved process of butadiene-1,3 polymerization employing a cycloalkane solvent and from 0.1 to 2 percent by weight of an alkyl substituted benzene as a polymerization regulator.
		Cycloalkanes useful in the process are those having 5 to 8 carbon atoms in the rings.

		Natürlich vorkommende Cycloalkane (Cyclopentan, Cyclohexan, Cycloheptan) wurden zuerst vom Chemiker Wladimir Wassiljewitsch Markownikow in der Rohbenzin-Fraktion, auch Naphtha genannt, des kaukasischen Erdöls gefunden.
		In der Sprache der Erdölwirtschaft ist Naphthen noch heute eine gebräuchliche Bezeichnung für diese Cycloalkane.
		Cycloalkane mit einem Kohlenstoffanteil von 14 bis 18 kommen zum Beispiel in Riechstoffen wie dem Moschus vor, der aus einer Drüse der Moschushirsche (Moschidae) gewonnen wird.

	Rule A-11. Unsubstituted Compounds and Radicals# (MONOCYCLIC HYDROCARBONS)
		The generic name of saturated monocyclic hydrocarbons (with or without side chains) is "cycloalkane".
		11.2 - Univalent radicals derived from cycloalkanes (with no side chains) are named by replacing the ending "-ane" of the hydrocarbon name by "-yl", the carbon atom with the free valence being numbered as 1.
		The double and triple bonds are given numbers as low as possible as in Rule A-3.3.

	Cycloalkane Information
		Cycloalkanes are chemical compounds with a one or more rings of carbons to which hydrogens are attached according to the formula C
		Cycloalkanes with a single ring are named analogously to their normal alkane counterpart of the same carbon count: cyclopropane, cyclobutane, cyclopentane, cyclohexane, etc. The larger cycloalkanes, with greater than 20 carbon atoms are typically called cycloparaffins.
		Cycloalkanes are classified into small, normal and bigger cycloalkanes, where cyclopropane and cyclobutane are the small ones, cyclopentane, cyclohexane, cycloheptane are the normal ones, and the rest are the bigger ones.

		In der Systematik der organischen Chemie zählt man sie zu den cycloaliphatischen Verbindungen, die Cycloalkane sind eine Untergruppe der Alkane, den kettenförmigen, gesättigten Kohlenwasserstoffen, sie werden aufgrund bestimmter Unterschiede meist getrennt von den Alkanen behandelt.
		Daraus ergibt sich ein weiteres Einteilungsschema der Cycloalkane, man unterscheidet einfache Ringe der monocyclischen Alkane von verbundenen und verbrückten oder Spiroverbindungen der polycyclischen Alkane.

		Generally, the hydrocracking conditions are effective to convert polynuclear aromatics in the heavy aromatic gas oil into smaller partially hydrogenated aromatic and hydrogenated species, to convert some normal paraffins to isoparaffins and to convert sulfur and nitrogen present in the heavy aromatic gas oil to hydrogen sulfide and ammonia.

	Naming Cycloalkanes
		Cycloalkanes are ring structures with the general formula: C
		Use the cycloalkane as the parent chain if it has a greater number of carbons than any alkylsubstituent.
		If an alkyl chain off the cycloalkane has a greater number of carbons, then use the alkyl chain as the parent and the cycloalkane as a cycloalkyl-substituent.

	Liquid phase oxidation of cycloalkane compound (US6930209)
		A method for liquid phase oxidation of a cycloalkane compound is provided by which the cycloalkane compound intended to be oxidized mixes with water to form an azeotropic mixture, and then an oxygen enriched gas is introduced to perform an oxidation reaction.
		This method is particularly suitable for liquid phase oxidation of cyclohexane by using an oxygen enriched gas or pure oxygen, which not only enhances conversion rate and selectivity of the cyclohexane oxidation process but also improves process safety in the use of an oxygen enriched gas or pure oxygen for cyclohexane oxidation.

		Time-dependent density functional theory (TD-DFT) calculations of the photoabsorption of molecules in the vacuum region have been performed in order to aid in the design of transparent materials for use as photoresists for F2 lithography (157 nm).
		We have used the TD-DFT approach to predict the photoabsorption of substituted benzenes, and cycloalkane including norbornane.
		The calculations show that norbornane is the best cycloalkane on which to start substitution studies.
