Abstract

Vaporization enthalpies for methyl myristoleate (methyl  Z  9-tetradecenonate), methyl 10-pentadecenoate, methyl palmitoleate (methyl  Z  9-hexadecenoate), methyl  Z  10-heptadecenoate, methyl oleate (methyl  Z  9-octadecenoate), methyl linoleate (methyl  Z , Z  9,12-octadecadienoate), methyl linolenate (methyl  Z , Z , Z  9,12,15-octadecatrienoate), methyl  Z  11-eicosenoate, methyl  Z , Z  11,14-eicosadienoate, methyl  Z , Z , Z  11,14,17-eicosatrieneoate, methyl arachidonate (methyl  Z , Z , Z , Z  5,8,11,14-eicosatetraeneoate), methyl  Z , Z , Z , Z , Z  5,8,11,14,17-eicosapentaeneoate, methyl erucate (methyl  Z  13-docosaneoate), methyl  Z , Z  13,16-docosadienoate, methyl  Z , Z , Z , Z , Z , Z  4,7,10,13,16,19-docosahexaenoate and methyl nervonate (methyl  Z  15-tetracosenoate) are evaluated at  T  = 298.15 and vapor pressures are evaluated over the temperature range  T  = 298.15–450 K by correlation gas chromatography. The results are generated by an interpolative process using literature values for the saturated fatty acid methyl esters (FAMEs) from methyl decanoate to methyl tetracosanoate, exclusive of methyl nonadecanoate, heneicosanoate and tricosanoate, as standards. Relationships for calculating vapor pressures for all of the compounds studied from  T  = 298.15 to 450 K are provided.
