As shown in Table 8, the spray paint solvent is predominately a mixture of several linear aliphatic, branched aliphatic, and cycloaliphatic hydrocarbons, and toluene, xylenes, and ethyl benzene. 2-Butanone (also known as methyl ethyl ketone) was also detected. The breakdown of the solvent mixture by class of compound (aromatic, //-alkane, iso-alkane, cyclic alkane, and others) is shown in Table 9. The solvent appears to be consistent with a mixture of a VM P naphtha... 

The major petroleum resources contain linear, saturated hydrocarbons (alkanes), cyclic alkanes, and aromatics. For the most part, this material is considered to have low free-energy content.

Reactions of alkanedwarboxyhe acids with sulfur tetrafluoride afford, in general, mixtures of bis(tnfluoromethyl)alkanes, cyclic a,tx,ot, oi -tetrafluoro ethers, linear bis(pentafluoroalkyl) ethers, and polyfluoroethers The cyclic ethers constitute the major products of the reactions with alkane-1,2 dicarboxylic acids, they are also formed in the reactions with alkane-1,3-dicarboxyhc acids but not with 1,1- nor 1,4-dtcarboxylic acids [211] (equation 105)... 

The selective substitution of tertiary hydrogens with dilute elemental fluorine (5% in nitrogen) is successfully achieved in a range of noncyclic alkanes, cyclic alkanes, and even steroids (Table 1). A typical experimental procedure is given for the formation of 2.9... 

In this discussion, polar compounds are defined as those that are capable of hydrogen bonding with other polar molecules. Thus, carboxylic acids, phenols, carbazoles, and amides are polar molecules. In addition, molecules such as pyridine benzologs are polar because they can hydrogen bond with carboxylic acids and phenols. Nonpolar molecules are those such as normal alkanes, cyclic alkanes, and aromatic hydrocarbons— molecules that normally do not associate with hydrogenbonding molecules. 

Simple (symmetrical) ethers have the general formula R—O—R or Ar—O—Ar mixed (unsymmetrical) ethers are R—O—R or Ar—O—Ar or Ar—O—R. The derived system names R and Ar as separate words and adds the word ether. In the IUPAC system, ethers (ROR) are named as alkoxy- (RO-) substituted alkanes. Cyclic ethers have at least one O in a ring.

In general, aldehydes, ketones, acids, esters, and acid chlorides are all reduced to the corresponding alcohols hy this reagent. Alkyl halides are unreactive towards DIBAL. Amides are reduced to amines, while nitriles afford aldehydes upon hydrolysis of an intermediate imine. Isocyanates are also reduced to the corresponding imines. Nitro compounds are reduced to hydroxy-lamines. Disulfides are reduced to thiols, while sulfides, suhbnes, and sulfonic acids are unreactive in toluene at 0°C. Tosylates are converted quantitatively to the corresponding alkanes. Cyclic imides can be reduced to carbinol lactams. 

The word oil is used for an organic phase that is essentially immiscible with water and is thus relatively apolar. It can refer to a hydrocarbon, a partially or totally chlorinated or fluorinated hydrocarbon, single-chain alkane, cyclic or aromatic hydrocarbon, polar monoester such as ethyl oleate, long-chain alcohol such as dodecanol, triglyceride natural oil, or polycyclic cholesterol. The most typical oil phase is, of course, n-alkane, which would be characterized by its length or alkane carbon number (ACN). 

As was the case for acyclic alkanes, cyclic alkanes may also be found as substituents. Again, the -ane ending is changed to -yl, as in 2-cyclopropylpentane ...

Petroleum is a mixture of liquid hydrocarbons of variable composition depending on its origin alkanes, cyclic hydrocarbons (cyclopentane, cyclohexane), and aromatic hydrocarbons. Crude oil always contains light gases (methane, ethane), particles in suspension, more or less brackish fossil water, and sulphur compounds. The sulphur content ranges from 0.5 to 3 %, depending on its origin.
