The present paper reports a differential scanning calorimetry (DSC) study of 19 industrially important compounds that lacked key experimental data in their respective two-phase vapor liquid regions. The compounds are o-tolualdehyde (CAS 529-20-4), m-tolualdehyde (CAS 620-23-5), p-tolualdehyde (CAS 104-87-0), 3-methylbenzyl alcohol (CAS 587-03-1), p-toluic acid (CAS 99-94-5), 1-phenyl-1-propanol (CAS 93-54-9), 1-phenyl-2-propanol (CAS 698-87-3), 2-phenyl-1-propanol (CAS 1123-85-9), 2-isopropylphenol (CAS 88-69-7), 2,5-dimethylfuran (CAS 625-86-5), 5-methylfurfural (CAS 620-02-0), phenyl acetate (CAS 122-79-2), ethyl 2-phenylacetate (CAS 101-97-3), n-hexylcyclohexane (CAS 4292-75-5), 6-undecanone (CAS 927-49-1), 1H-perfluorooctane (CAS 335-65-9), 2,6-dimethoxyphenol (CAS 91-10-1), trans-isoeugenol (CAS 5932-68-3), and 1-propoxy-2-propanol (CAS 1569-01-3). New experimental melting temperatures, enthalpies of fusion, glass transition temperatures, and heat capacities of the liquid compounds as a function of temperature are reported with a comparison to similar compounds.
