摘要
Phosphate and phosphite mono and diesters in small amounts function as antifoulant additives in ethylene cracking furnaces which are subjected to elevated temperatures from about 500 1700.degree.F. These furnaces produce material that deposits and accumulates upon furnace surfaces including furnace coils and transfer line exchangers. The present antifoulant additives inhibit and suppress fouling and also help clean up previously fouled furnace surfaces.
