Solid-phase behavior of several long-chain n-paraffins, esters, and a ketone

The long•spacings of the co mpound s meth yl stea rate , eth yl stearate , n•butyl stea rate , 2• non• adeca none , n-eicosa ne , n-hexatriaco ntane a nd n-tetratetraco ntan e have bee n examin ed as a fun ction of temperature by mean s of low-a ngle x-ray diffraction.The intensity of the long-s pacin g wa s also determin ed versus te mperature_ The e ffect of ann ealing temperature and tim e was exa min ed by means of the DSC.Diel ectri c loss was studi ed in two crystallin e ph ases of n-but yl stea rate.
