Abstract:
A method for preparing a new crystalline form of γ-aminobutyric acid, including the steps of: S1: preparing a γ-aminobutyric acid solution at an initial concentration of 0.5-1.0 g/mL by adding crude γ-aminobutyric acid to water; adding an additive to the γ-aminobutyric acid solution, raising the temperature to 50-80° C., stirring to produce a clear solution; and S2: obtaining a suspension by evaporating water from the product of S1 under reduced pressure and at 50-80° C.; obtaining a wet product by filtering the suspension; drying the wet product to obtain the new crystalline form of γ-aminobutyric acid. The preparation method of the new crystalline form of γ-aminobutyric acid is simple, easy to operate, low in energy consumption, economical and environmentally friendly. It is suitable for large-scale industrial production.

Claim (Index 1):
