Potassium Hydroxide → Potassium Lauryl Phosphate

Participants

Reaction Steps

In the same manner as for Example 4, 502.9 g dodecyl phosphate from Example 3 was added to 232.1 g potassium hydroxide solution (44.9 wt. %), diluted with an additional 595.2 g deionized water, over a 25 min. period and temperature range of from 61° to 81° C. The resulting potassium/phosphorus molar ratio of 0.99 was near the intended 1.00, stoichiometric ratio for the 43.1% salt solution and the pH of the modestly viscous, pearlescent liquid at room temperature was 6.0.
