実験手順
Examples XII-XXVII elucidate the conditions at which lactitol monohydrate and lactitol dihydrate, respectively, may be obtained from aqueous solutions of lactitol. In each instance 200 g lactitol dihydrate was used as the starting material which wasd dissolved in an amount of water varying from 40 g to 50 g at 100° C. Thereupon the solutions obtained were cooled to a temperature varying from 25° C. to 45° C. and seeded with 2 g monohydrate or 2 g dihydrate. The crystallization proper occurred at temperatures between 18° C. and 45° C.
