Abstract
A process for the restoration of the initial chemical lighting potential of the oxalate component of a chemiluminescent lighting system. The oxalate component comprises an oxalate diester in a first liquid solution which prior to restoration exhibits a failure to produce initial high intensity luminosity upon mixture of the oxalate component with a liquid activator component comprising a peroxide in a second liquid solution. The process comprises contacting the oxalate component with magnesium silicate or calcium silicate for a period of time sufficient to correct the failure and thereafter separating the oxalate component from the selected silicate.
