1-heptanol (short- heptanol ; interchangeably 1-heptyl alcohol ) is a chemical compound from the substance group of alkanols . In addition to 1-heptanol, there are other isomers , for example 2-heptanol , 3-heptanol and 4-heptanol .
Extraction and presentation
Mainly, 1-heptanol by reduction of heptanal by hydrogen addition produced:
In addition, 1-heptanol occurs in small quantities in petroleum .
properties
1-Heptanol is a colorless, hardly inflammable liquid with a characteristic odor, which is sparingly soluble in water. The refractive index is 1.424 (at 20 ° C and the D-line of sodium light).
use
1-Heptanol is used in the perfume industry as an additive for clove and jasmine fragrances. It is used as a solvent for linseed oil, shellac and as a diluent for resins and celluloses. By reaction of 1-heptanol with thionyl chloride in pyridine can one-chloroheptane be won.
safety instructions
The vapors of 1-heptanol can form an explosive mixture with air ( flash point 70 ° C, ignition temperature 275 ° C, lower explosion limit 0.89 vol.% Or 43 g · m −3 ).
