摘要：
The present invention relates to a process for the preparation of storage-stable iminodisuccinate solutions, by subjecting an aqueous solution of iminodisuccinate having an ammonia content of less than 20 ppm to thermal treatment at 40 to 120° C. for 5 hours up to 300 days and subsequent distillation at
