    • 专利摘要:
    The invention relates to a process for recovering salts of aspartic acid corresponding to the general formula <IMAGE> in which either n = 1 and Me is an alkali metal or n = 2 and Me is an alkaline earth metal or a divalent heavy metal and X represents an integer or a fractional number having a value of from 0 to 4, depending on the cation present, which comprises spray drying a solution of the salt at temperatures in the range from 500 DEG C to 20 DEG C. Preferably the spray drying is carried out at temperatures in the range from 300 DEG C to 80 DEG C. The salts are obtained in a substantially quantitative yield and in highly pure form during spray drying.
