Negative excess surface tension was observed in the whole concentration range, indicating an enrichment of the surface region by n-pentane. The parameters of the model (SPTM3) for n-pentane and n-heptane were calculated and reported. By continuing you agree to the use of cookies. Surface tension of vinyl acetate: Supplement to Volume IV/24. It also shows the saturation pressure with changes in temperature. https://doi.org/10.1016/j.jct.2009.07.018. There is no information available on the methods used to determine the value for this endpoint. This chapter provides surface tension of exo-tetrahydrodicyclopentadiene at various temperatures. To read the full-text of this research, you can request a copy directly from the author. Chemical, physical and thermal properties of pentane:Values are given for liquid at 25oC /77oF / 298 K and 1 bara, if not other phase, temperature or pressure given. This chapter provides surface tension of propanoic acid at various temperatures. The phase diagram for pentane shows the phase behavior with changes in temperature and pressure. Density of pentane with varying temperature and pressure. This means there is more opportunity for charge imbalance, and more opportunity for attraction between molecules. The curve between the critical point and the triple point shows the pentane boiling point with changes in pressure. So why does octane have more surface tension than pentane?

Hoar and Melford's equation was the best. This information has not been reviewed or verified by the Agency or any other authority. If you are concerned with formulation problems which involve surface wetting, solubility, and viscosity control, you may wish to consult both tables. This chapter provides surface tension of the binary liquid mixture of water and benzylamine at various temperatures. This is supported by a value of 15.49 mN/m at 25°C from the CRC Handbook (Lide 2008). The parameters of the model (SPTM3) for n-pentane and n-heptane were calculated and reported. It belongs to the organic class alkanes, and is naturally present in crude oils and condensates. The selected reference fluids were n-pentane for the range C 2 –C 7, n-decane for C 8 –C 12 and C 15 for those n-alkanes with >12 carbon atoms. New experimental results are reported for the surface tension of normal pentane, hexane, heptane, and octane. New experimental results are reported for the surface tension of normal pentane, hexane, heptane, and octane. Equations for calculating the surface tension of these n-alkanes as a function of temperature are presented.

The boling point 36°C/97°F, and the vapors are heavier than air. This chapter provides surface tension of pentane at various temperatures. It is a component of some fuels and is employed as a specialty solvent in the laboratory. The comparison between the mixture surface tension results and those calculated by the model indicate that the new proposed model can be satisfactorily used for calculating the surface tension of n-pentane, n-heptane and their mixtures.

This range has been agreed by the consortium to represent the substance. The surface tension is between 13 and 17 mN/m at 25°C for n-pentane based on Wilhelmy plate methodology. Welcome to the ECHA website. The surface tension is between 13 and 17 mN/m at 25°C for n-pentane based on Wilhelmy plate methodology. This chapter provides surface tension of the binary liquid mixture of dimethylsulfoxide and propan-1-ol at various temperatures. Pentane is a liquid at standard conditions. The comparison between the mixture surface tension results and those calculated by the model indicate that the new proposed model can be satisfactorily used for calculating the surface tension of n-pentane, n-heptane and their mixtures. The comparisons between the obtained surface tension data and those calculated by the SPTM3 model indicate that the data can be described with deviations less than 1.56%.
