Use of tributoxyethylphosphate to control foam in the production of soda ash from trona

Tributoxyethylphosphate is useful in controlling foam produced during the evaporative crystallization of calcined trona solutions. The chemical is effective at low concentrations, i.e. 1 to 30 ppm, and does not significantly alter the crystal habit of the sodium carbonate crystals.
