Yield:-
Reaction Conditions:
magnesium chloride at 120; under 50 - 150 Torr; for 5.5 - 7 h;Product distribution / selectivity;
Steps:
1; 2; 3; 4; 5; 6
To the phosphochloridate mixture (6.4 wt% phenyl dichloridophosphate (MPCP), 89.7 wt% diphenyl chloridophosphate (DPCP), 3.9% triphenyl phosphate (TPP), and about 0.1wt% MgCl2) 2-ethylhexanol was added via sub-surface addition at reaction conditions. Table 1 summarises the reaction conditions and the crude product compositions for both the laboratory scale and pilot scale experiments. Acceptable product quality is achieved under all reaction conditions summarised in Table 1. Efficient HCI removal is required for minimising the by-product formation. In these examples vacuum is the key method for HCI removal.
