What are Antoine coefficients for propylene?

Answer 1

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

Answer 2

The Antoine coefficients for propylene are A=4.62158, B=1221.442, and C=-35.221°C. These coefficients are used in Antoine's equation to estimate the vapor pressure of propylene over a range of temperatures.

Answer 3

Here's what I was able to find at 3 different temp ranges:

Temp range (K):

277.5 - 360.8 K A: 4.53678 B: 1149.360 C:24.906

230.5 - 320.6 K A: 3.98292 B: 819.296 C:-24.417

166.02 - 231.41 K A: 4.01158 B: 834.260 C:-22.763

P is in units of bar, T is in K for these coefficients.

Answer 4

According to The Dortmund database: Antoine equation for Propylene log P =A-B/(t+C) t (C), and P (mm Hg) Valid between -51 and 91 C A = 7.0823 B = 905.7 C = 263.387

Answer 5

A=7.23160 B=1277.030 C=237.230 enjoy
