Betaine recovery process.

摘要: Betaine is recovered from natural sources such as beet molasses, rest molasses and vinasse by diluting the to 25-50% solids, introducing top of a chromatographic column containing salt polystyrene sulfonate cation exchange resin cross-coupled with about 2 12 weight percent divinylbenzene, eluting water collecting fraction betaine downstream side resin. When successive feeds predetermined intervals are made, may be partly overlapped. The preceding feed then eluted dilute following feed. evaporated under vacuum crystallized anhydrous crystals or monohydrate.
