Pentanes Pentanol

Reduction of 1-pentanol to pentane reportedly occurs during condensation of samarium with excess alcohol (86).

The 0x0 process is used to convert the C4 fraction to C5 derivatives. Synthesis gas is catalytically reacted with 1-butene to give pentanal which can be hydrogenated to 1-pentanol ( -amyl alcohol), giving a route to C5 compounds in larger amounts than what would be available from C5 alkanes in petroleum.

The direct gas chromatography/mass spectrometry metliod was also used to study the volatiles in com-soy food blends without prior treatment or enrichment of the sample. As shown in chromatogram B of Figure 3, the inferior sample has a much greater concentration of volatile components than does the good (control) sample shown in chromatogram A. The inferior sample has large amounts of pentanal, 1-pentanol, hexanal, 1-hexanol, 2-heptanone,...

Conducting the same experiment using tril-inolein produced volatiles unique to the trili-nolein substrate, with the major classes being alkanals, 2-alkenals, 2,4-alkadienals, and hydrocarbons. Those volatiles, produced uniquely from this substrate and attributable to the breakdown of 9- and 13-hydroperoxides, include pentane, pentanal, 1 -pentanol, hexanal, 2-hexenal, 3-hexenal, 2-heptenal, 2-octenal, 2,4-decadienal, and acrolein. Addition of triolein afforded the added production of volatiles previously identified in triolein alone, but ad-... 

The OH substituent is attached internally (rather than terminally ) to the linear alkane chain of pentane the point of attachment is labeled a, which corresponds to C-3 of pentane, for which the shift value of 34.7 is given in Table 4.6. To this value is added the increment +41, this being the increment for an OH group attached internally to the a-carbon of 3-pentanol (see line 12, 2nd column of numbers). The shift, therefore, for the point of attachment (the...

I IS. Consider the compounds butanoic acid, pentanal, n-hexane, and 1-pentanol. The boiling points of these compounds (in no specific order) are 69°C, 103°C, 137°C, and 1 64°C. Match the boiling points to the correct compound.
