Chemie und Industrie
Anwendungen
VerwendenSodium Sesquicarbonate is a ph control agent that is prepared by: (1) partial carbonation of soda ash solution followed by crystallization, centrifugation, and drying; (2) double refining of trona ore, a naturally occurring impure sodium sequicarbonate. It is used in cream manufacture at a level of the ingredient sufficient to control lactic acid prior to pasteurization and churning of cream into butter.
Ergänzende Hinweise
Definitionsodium sesquicarbonate: A whitecrystalline hydrated double salt,Na2CO3.NaHCO3.2H2O, soluble inwater but less alkaline than sodiumcarbonate; r.d. 2.12; decomposes onheating. It may be prepared by crystallizingequimolar quantities of theconstituent materials; it also occursnaturally as trona and in SearlesLake brines. It is widely used as adetergent and soap builder and,because of its mild alkaline properties,as a water-softening agent andbath-salt base.
