Abstract
The present disclosure concerns processes for regenerating organocations from perchlorate-rich waste products, more specifically transformation of water-insoluble organocation-perchlorate salt, originating from perchlorate-removal water treatment processes, into a water-soluble perchlorate salt for reusing same.
Claims19
A process for recovering a water-soluble organocation salt from a substantially water-insoluble organocation-perchlorate, the process comprising:
- (a) contacting said substantially water-insoluble organocation-perchlorate with a first solution containing a first salt dissolved in an organic solvent, the first salt consisting of a metal cation and a balancing anion, under conditions permitting precipitation of metal-perchlorate salt and formation of a second salt dissolved in said organic solvent, the second salt consisting of the organocation and the balancing anion;
- (b) separating the metal-perchlorate salt from the organic solvent in which the second salt is dissolved;
- and
- (c) separating the organic solvent from the second salt to obtain said second salt, said second salt being a water-soluble organocation salt.

A process for obtaining water-soluble benzalkonium-hydroxide from substantially water-insoluble benzalkonium-perchlorate, the process comprising:
- (a) contacting an aqueous slurry of benzalkonium-perchlorate with a first solution containing potassium hydroxide dissolved in an organic solvent, under conditions permitting precipitation of potassium-perchlorate salt and formation of benzalkonium-hydroxide dissolved in said organic solvent;
- (b) separating the precipitated potassium-perchlorate from the organic solvent in which the benzalkonium-hydroxide is dissolve;
- and
- (c) separating the organic solvent from the benzalkonium-hydroxide to obtain a water-soluble benzalkonium-hydroxide,
- benzalkonium having the following formula (I):
- wherein
- R is a —(C3-C18) alkyl;
- R1 and R2 are each independently selected from H and —(C1-C6) alkyl;
- and
- R3 is one or more substituents, each independently selected from H, —(C1-C6) alkyl, —(C1-C6) alkoxy, —NHCO(C1-C6) alkyl, —OH, and —NH2.
