Cooling thermograms

Figure 3.1 DSC melting and crystallisation thermograms of palm oil. For melting thermogram, sample was cooled to — 30°C at rate of 40°C/min, held for 10 mins and heated to 80°C at 5°C/min for cooling thermogram, sample was melted to 80°C and cooled to —30°C at 5°C/min. Lm low melting fraction, Hm high melting fraction.

The properties of PPBC/EPDM blends strongly depend on the crystalline micromorphology of PPBC, as well as on the particle size and degree of dispersion of EPDM (Xavier et al. 1994). The DSC cooling thermograms indicated that the degree of crystallinity in PPBC decreased with increasing concentration of EPDM (Table 10.14 and Fig. 10.18).

Techniques such as microscopy or the use of a Coulter counter are common techniques to study O/W emulsion stability, but they are applicable only to dilute systems. DSC represents a suitable technique to characterize a W/O emulsion without disturbing the system. Characterization of a water-in-crude oil emulsion has been studied in the laboratory. The degree of undercooling and the probable temperature obtained from a cooling thermogram allows the determination of the distribution size of dispersed droplets. By knowing the latent heat of solidification, it is also possible to determine the number of droplets crystallized at temperature T. ...
