Abstract
Equations correlating the normal boiling points (TB), critical temperatures (TC) and critical pressures (PC) with the respective carbon numbers (n) were developed for the straight-chain homologous series H-(CH2)n-Y, where Y denotes CH3, OH, CH=O, OCOCH3 and COOH and n varies from 5 to 18. The estimates based on these equations were found to reproduce experimental data within the average errors less than 0.27% for TB and TC, and 1.45% for PC thus allowing a prediction of new data.
