Figure 40
1-Ethyl-3-(4-methylpentanoyl)urea – the three diagrams on the left-hand side show the variation of the edges of the reduced triclinic cell with temperature in the region of change. The scatter of the experimental points suggests that the errors (random plus systematic) are at least an order of magnitude larger than the error estimates (bracketed values) given in Table 13. The temperature dependence of the cell volume is shown on the right-hand side and below that the variation of the angles of the reduced cell on temperature, and the DSC trace (lower curve: heating endotherm, upper curve: exotherm obtained on cooling, with hysteresis). The diagrams use data given by Hashizume et al. (2003). |
