Any other information on results incl. tables

Analytical data are given in Table 3, showing distillation ranges between 218.5 -225.2ºC and 218.2 -225.0ºC for test 1 and test 2 respectively, from 5mL recovered to end point. The mean range is 218.4 -225.1. Recovery data are given in Table 4 and show a total recovery (distillate and residue) of 94.5 and 96.5 per cent for tests 1 and 2 respectively.
