Citric Acid → Trisodium citrate

Participants

Reaction Steps

An aqueous solution of sodium citrate was prepared by adding 38.8 gms. of sodium hydroxide to 620 gms. of water with stirring. When the sodium hydroxide dissolved, 880 gms. of anhydrous citric acid were added as stirring was continued. When the citric acid dissolved, 60 gms. of POLY-TERGENT SL-62 surfactant, 90 gms. of POLY-TERGENT SL-42 surfactant and 80 gms. of POLY-SOLV DPM glycol ether were added. An additional amount of 300 gms. of water containing 38.8 gm. sodium hydroxide was added. Stirring was continued until the mixture is homogeneous. The resulting formulation had a pH greater than 2.
