Table identifying density results for Monoesters of C16 and C18 (branched and linear) fatty acids with decan-1-ol at 20 °C and including the mean over multiple runs

 

Sample/Temperature (°C)	Decyl Isostearate at 20°C
Density 1 (g/cm³)	0.8607
Density 2 (g/cm³)	0.8609
Density 3 (g/cm³)	0.8607
Mean (g/cm³)	0.8608

 

The relative density of the sample at 20 °C, compared with water at 20 °C, is given by the following formula:

 

ρ^t_tw = ρ_t / ρ_tw = 0.8608 / 0.9982 = 0.8623

Conclusions:

The relative density of Monoesters of C16 and C18 (branched and linear) fatty acids with decan-1-ol at 20 ºC is 0.8623

Executive summary:

The density of Monoesters of C16 and C18 (branched and linear) fatty acids with decan-1-ol was determined using a method consistent with standard method ASTM D7042. As such the density of Monoesters of C16 and C18 (branched and linear) fatty acids with decan-1-ol was found to be 0.8623 at 20ºC.
