What are Antoine coefficients for CH4?
The Antoine coefficients for isobutane in the temperature range of -83°C to 7°C are A=13.8254, B=2181.79, C=248.870. These coefficients are valid for Antoine's equation in the form of ln(Psat [kPa]) = A - B/(T[°C] + C). (Source Introduction to Chemical Engineering Thermodynamics 7th ed by J.M. Smith, p.682)
What are Antoine coefficients for propylene?
From Lange's Handbook of Chemistry: For the equation Log10 (P) = A - B/(C + t), where "P" is the vapor pressure in mm of mercury, and "t" is the temperature in degrees centigrade, the coefficients for propanol are: A = 7.99733, B = 1569.70, and C = 209.5
What is 'azote'?
The word 'azote' is French for nitrogen. It's the name that was given to nitrogen by pioneering French scientist Antoine-Laurent de Lavoisier [26.viii.1743-8.v.1794]. The word comes from the Greek words for 'without life'.

Antoine coefficients Light Naphtha?
The Antoine coefficients are empirical constants used in the Antoine equation to describe the relationship between vapor pressure and temperature for a given substance. For light naphtha, these coefficients enable the calculation of vapor pressure at various temperatures, which is crucial for processes like distillation and refining in the petrochemical industry. Typically, the coefficients are determined experimentally and can vary based on the specific composition of the naphtha. Generally, light naphtha has a boiling range of about 30°C to 90°C, and its vapor pressure characteristics are essential for safe handling and processing.
What are Antoine Coefficient for H2S?
The Nation Institute of Standards and Technology web site has the figures Note there are three coefficients - the Antoine equation gives a reasonable fit to vapour pressure.
What were the steps taken to discover nitrogen?
Daniel Rutherford discovered nitrogen in 1772; Antoine Lavoisier was the first to consider nitrogen as a chemical element.
Who discovered nitrogen?
Nitrogen was isolated by the British physician Daniel Rutherford in 1772, but was not recognized as an element until 1776 by the French chemist Antoine Laurent Lavoisier.

Antoine coefficient for mercury?
The Antoine coefficient for mercury is a set of temperature-dependent constants used in the Antoine equation to describe the vapor pressure of mercury as a function of temperature. These coefficients are specific to mercury and are commonly used in chemical engineering and thermodynamics to model and predict the behavior of mercury in various processes.
Why nitrogen gas is called as azota?
The name "azote" for nitrogen gas is derived from the Greek word "azote" meaning "lifeless" because nitrogen is an inert gas that does not support combustion or sustain life. It was later changed to "nitrogen" by French chemist Jean-Antoine Chaptal.
