In rule 6 of the Li6ge Rules, which deals with saturated aliphatic hydrocarbons with side chains, definite instructions are given for naming these compounds. However, if a simpler name would result, another prescribed way of naming should be used. The simplicity of a name is obviously very much a question of personal opinion. Consequently, in this instance also, more than one method of naming is officially tolerated. 

The definition of how soluble a gas is in water is relative, as a gas may be regarded as soluble in one context but insoluble in another. For example, acetone with //A — 25.6Matm-1 is very soluble compared to aliphatic hydrocarbons but is insoluble compared to formaldehyde with HA = 6300 M atm-1. A useful solubility benchmark for... 

The references cited for a parficular tobacco and/or tobacco smoke component may deal with its identification or with a variety of topics pertinent to the particular component. Topics may include such simple items as the isolation and identification of a component, its characterization by classical chemical means, for example, the definition of the structure of solanesol isolated from flue-cured tobacco by Rowland et al. (3359), or the characterization of a component by spectrographic means, for example, UV, IR, NMR, MS, and chromatographic retention time. One example is the identification by Snook et al. of many PAHs (3756-3758) and aza-arenes (3750) in cigarette mainstream smoke (MSS). Many references cited herein describe the search for and elucidation of the precursor in tobacco of a particular component in cigarette MSS (3616), for example, the saturated aliphatic hydrocarbon precursors of the PAHs, including benzo[fl]pyrene (B[a]P) the quantitation of the component on a per gram of tobacco basis or on its per cigarette MSS... 

The definition of how soluble a gas is in water is relative as a gas may be regarded as soluble in one context but insoluble in another. For example, acetone with = 25.6 M atm is very soluble compared to aliphatic hydrocarbons but is insoluble compared to formaldehyde with — 6300 M atm . A useful solubility benchmark for atmospheric applications is the distribution of a species between the gas and the aqueous phases in a typical cloud species that reside mainly in the gas phase are considered insoluble, and species that are almost exclusively in the aqueous phase are considered very soluble. Intermediate species, with significant fractions in both phases, are considered moderately soluble. Let us formulate the above statements mathematically by defining the aqueous/gas-phase distribution factor. 

The UVCB definition for this substance is A complex combination of hydrocarbons separated as a liquid from natural gas in a gas recycling plant by processes such as refrigeration or absorption. It consists mainly of saturated aliphatic hydrocarbons having carbon munbers in the range of C2 through C8. This substance includes variable carbon chain lengths. ...
