Zusammenfassung:	The previous processes for obtaining desensitised aliphatic diperoxydicarboxylic acids using sodium sulphate intrinsic to the process are difficult in terms of safety because of the production of sodium sulphate in the presence of the diperoxydicarboxylic acid and are only controllable with losses; impurities such as heavy metals must additionally be virtually completely removed in a complicated manner by means of the sodium sulphate-containing waste liquors produced during the desensitisation in order not to impair the stability of the products. The new process should not have the disadvantages mentioned. To this end, a new process is proposed that yields, on the basis of process sodium sulphate, improved diperoxydicarboxylic acid granules which do not have the abovementioned disadvantages. On the basis of process sodium sulphate, improved diperoxy- dicarboxylic acids are obtained in a safe process and have a good chemical stability in spite of a high content of impurities, safe handling ability, low bulk weights and high resistance to abrasion. Preparation of desensitised aliphatic diperoxydicarboxylic acids.
