Persulfates, perhaps the least known of peroxygen chemicals, have unique properties which make them useful in processes involving polymerization and depolymerization, organic synthesis and others. This class of peroxygen compounds has applications in such diverse fields as textiles, soap, rubber, adhesives and others in which unique properties expedite processing. It is possible you have problems in which persulfates may be helpful. We suggest that you write for Becco Bulletins No. 34 and

68, which are bibliographies on the uses of persulfates. They contain 184 references in ineuGen specific and a number of miscellaneous fields, including cellulose chemistry, fur bleaching and carroting, photographic chemistry, starch processing, metal surface treatment, etc. Also, your technically trained Becco representative can discuss your problems from a specific and practical standpoint. Becco Ammonium and Potassium Persulfates are two among many peroxygen chemicals of which Becco is a leading producer.
