Abstract: 1. A PROCESS FOR THE CONTINUOUS PREPARATION OF ALKYLPEROXYDICARBONATES IN SOLUTION FROM SODIUM PEROXIDE AND ALKYLCHLOROFORMATES COMPRISING CONGINUOUSLY CIRCULATING IN A REACTION CHAMBER AN AQUEOUS LIQUID MAINTAINED AT A TEMPERATURE OF AT LEAST -10* C., CONTINUOUSLY INTRODUCING INTO SAID AQUEOUS LIQUID HYDROXIDE, HYDROGEN PEROXIDE IN A STOICHIOMETIC EXCESS OF 10-20%, ALKYLCHLOROFORMATE AND A SOLVENT FOR SAID ALKYLPEROXYDICARBONATE, AT FLOW RATES SUCH THAT THE PJ OF THE AQUEOUS LIQUID IS CONSTANTLY MAINTAINED AT A VALUE WITHIN THE RANGE OF 3 TO 10, WHEREBY THE AMOUNT OF SODIUM HYDROXIDE FORMED IS IN EXCESS OF 10-20% BY WEIGHT OF THE ALKYLFORMATE SODIUM PEROXIDE CHIOMETRIC RATIO OF THE ALKYLFORMATE/SODIUM PEROXIDE, CONTINUOUSLY SEPARATING THE OBTAINED SOLUTION OF ALKYLPEROXYDICARBONATE FROM THE AQUEOUS LIQUID, WASHING SAID SOLUTION WITH WATER, AND SEPARATING THE WASHED SOLUTION OF ALKYLPEROXYDICARBONATE FROM THE WASH WATER.
