Vapor–liquid critical point measurements of fifteen compounds by the pulse-heating method

• Critical properties of compounds of industrial importance were measured.
• All the compounds studied decompose at near-critical temperatures.
• Pulse-heating method with short residence times was used.

The critical temperatures and pressures have been measured by the pulse-heating method for fifteen compounds: benzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, 4-methylbenzoic acid, benzaldehyde, 4-methylbenzaldehyde, phenylmethanol, (4-methylphenyl)methanol, 2-carboxybenzaldehyde, 1,3-propanediol, 2,2-dimethyl-1,3-propanediol, methyl tetradecanoate, methyl hexadecanoate, methyl octadecanoate, and (Z)-9-methyl octadecenoate. The experimental critical properties have been compared with those estimated by the Wilson/Jasperson and Marrero/Gani methods.
