Abstract: PRODUCTION OF SODIUM BICARBONATE BY REVERSION OF NaHCO3-CONTAINING DOUBLE SALT Sodium bicarbonate is produced by introducing solid sodium sesquicarbonate and/or Wegscheider's salt into a reversion slurry, saturated with respect to bicarbonate and containing at least 10 wt. % solids, to effect rapid and complete conversion of the feed solids to crystal- line sodium bicarbonate which is recovered from the slurry. Carbon dioxide is introduced into the reversion liquor to maintain its composition at a relatively constant value, preferably in a region of the Na2CO3- NaHCO3-H2O phase diagram that minimizes the equili- brium partial pressure of CO2 vapor above such liquor.
