QuinaII,* IDepartment of Chemistry, Davidson College, 28035 Davidson, NC, USA IIInstituto de Química, Universidade de São Paulo, CP 26077, 05513-970 São Paulo-SP, Brazil ABSTRACT Boiling points (TB) of acyclic alkynes are predicted from their boiling point numbers (YBP) with the relationship TB(K) = -16.802YBP2/3 + 337.377YBP1/3– 437.883. In turn, YBP values are calculated from structure using the equation YBP = 1.726 … Continue reading “A simple method to evaluate, correlate and predict boiling and flash points of alkynes”

The data were provided by the Design Institute for Physical Property Data (DIPPR) Project 801 database. These data sets were composed of 298 hydrocarbons and heteroatom-containing structures including N compounds (data set I), … Continue reading “Prediction of the Normal Boiling Points of Organic Compounds from Molecular Structures with a Computational Neural Network Model”
