1-Heptanol is an alcohol with a seven carbon chain and the structural formula of CH 3 (CH 2) 6 OH. [1] It is a clear colorless liquid that is very slightly soluble in water, but miscible with ether and ethanol .
Numerical values of these thermodynamic properties are collected as tables or are calculated from thermodynamic datafiles. Data is expressed as temperature-dependent values for one mole of substance at the standard pressure of 101.325 kPa (1 atm), or 100 kPa (1 bar).
On the other hand, some constants, such as K f (the freezing point depression constant, or cryoscopic constant), depend on the identity of a substance, and so may be considered to describe the state of a system, and therefore may be considered physical properties. "Specific" properties are expressed on a per mass basis.
The formation of heptanal in the fractional distillation of castor oil [3] was already described in 1878. The large-scale production is based on the pyrolytic cleavage of ricinoleic acid [4] (Arkema method) and on the hydroformylation of 1-hexene with rhodium 2-ethylhexanoate as a catalyst upon addition of some 2-ethylhexanoic acid (Oxea method): [2] [5]
Heptanol may refer to any isomeric alcohols with the formula C 7 H 16 O: 1-Heptanol, an alcohol with a seven carbon chain and the structural formula of CH 3 (CH 2) 6 OH; 2-Heptanol, a secondary alcohol with the hydroxyl on the second carbon of the straight seven-carbon chain; 3-Heptanol, an organic alcohol with the chemical formula C 7 H 16 O ...
The thermodynamic properties of materials are intensive thermodynamic parameters which are specific to a given material. Each is directly related to a second order differential of a thermodynamic potential. Examples for a simple 1-component system are: Compressibility (or its inverse, the bulk modulus) Isothermal compressibility
Thermophysical properties are characteristics that control the diurnal, seasonal, or climatic surface and subsurface temperature variations (or thermal curves) of a material. The most important thermophysical property is thermal inertia , which controls the amplitude of the thermal curve and albedo (or reflectivity ), which controls the average ...
Heptyl acetate (C 9 H 18 O 2), also known as acetate C-7, [citation needed] is a colorless alcohol-soluble liquid that is the ester formed by the condensation of 1-heptanol and acetic acid. Heptyl acetate is used as a fruit essence flavoring in foods and as a scent in perfumes. It has a woody, fruity, rumlike odor and a spicy, floral taste with ...
