- Propylheptanol is
a mixture of isomeric decyl alcohols: 2-propylheptanol,
4-methyl-2-propylhexanol and 5-methyl-2-propylhexanol.
- It is a clear and
colorless, high boiling liquid with a mild characteristic odor. It
is miscible with most common organic solvents but has very low water
solubility.
- 2-Propylheptyl
alcohol is "oxoalcohol", meaning that it is produced from the
hydroformylation ("oxo synthesis") of C9 alkenes followed by
hydrogenation of the resulting aldehyde. The production route is
similar to that for tripropylene.
- 2-propylheptanol
(2-PH), which is derived from valeraldehyde. World consumption of
valeraldehyde will grow at the highest rate of all oxo chemicals,
largely as a result of the commissioning of 2-PH capacity in Europe
and China starting in late 2009 and continuing into 2013.
- Synonyms are
2-Propylheptanol, 2-Propylheptan-1-ol, 1-Heptanol, 2-propyl-,
2-PROPYL-1-HEPTANOL, 2-Propylheptyl alcohol.
- Phthalate esters
prepared from this alcohol offer a number of advantages for flexible
PVC applications, such as low volatility in vinyl for automotive
products, long-term property retention, and excellent outdoor
performance properties.
- Demand for oxo
chemicals in the United States is expected to grow moderately, at an
average annual rate of almost 2% during 2008–2013. The long-term
prospects for oxo chemicals in Western Europe improved considerably
during 2005–2008, as consolidations and capacity reductions resulted
in improved efficiencies and capacity utilization.
- Demand for
plasticizer alcohols largely follows the patterns of the leading
world economies. The major end-use markets include
construction/remodeling, automotive production and original
equipment manufacture (OEM).
- The major
plasticizer producing regions, such as the United States and Western
Europe, are experiencing moderate growth rates, while Japan is
expected to see flat growth for plasticizers.
- BASF is the
largest producer of plasticizer alcohols, with production facilities
in the United States, Germany, China and Malaysia.
