Abstract
Dialkyl peroxydicarbonates are prepared in aqueous reaction media, washed with water, and then dried with sodium sulfate, calcium chloride, or the like. Peroxydicarbonates, particularly heat-sensitive peroxydicarbonates, may be dried safely and more effectively with the use of molecular sieves by contacting substantially phase water free peroxydicarbonate with sieves. Contact between heat-sensitive peroxydicarbonate and sieves should be effected in a way that avoids abrupt, excessive warming of peroxydicarbonate.
