Atomic Parachors The values for a given compound are expressed as sum of the
numbers and nature of atoms present called atomic parachors. Knowing that
each CH, group has a parachor value of 39, while decane C|0H,, has a parachor

critical temperature, as described by the following Eqs. (8) and (9). M P = (8) ρl −
ρv σ 1/4 where P is the parachor, ρl and ρv denote densities of liquid and vapor
phases, respectively, σ is the surface tension, and M is the molecular weight.

Chemical Property Estimation: Theory and Application
Estimating the surface tension from the value of parachor produces an average
error of 4.5% and a maximum error of -20% with a test set of 28 polar, nonpolar,
and hydrogen- bonding liquids (Reid etal., l987l. McGowan (l952l reports ...

Surface tension and the parachor McLeod (1 923) reported that the surface
tension of a liquid could be related to the difference in density between the liquid
and its vapour by the relation 7 = C(p,-pvr, (1.18) where C and m are constants,
and ...

Multiplying both sides of the equation by M, the molecular weight of the
substance, we get, =MC = constant = [P] The constant P was called the parachor
by Sugden. Since the density of the saturated vapour can be ignored in
comparison with ...

Q. What is parachor ? □»" The parachor, may be defined as the molar volume of
a liquid at a temperature at which its surface tension is unity. Suppose at a
particular temperature, the surface tension is unity, then Mm/d\s molar volume.
