Zusammenfassung:	C-7818 PROCESS FOR PREPARING LIQUID TRIARYL THIOPHOSPHATE MIXTURES Liquid mixed triaryl thiophosphate mixtures can be prepared by forming a mixture of phenol and substituted phenols, forming a phosphite from that mixture and sulfurizing the phosphite, washing the thiophosphate with aqueous base, and drying the so washed thiophosphate under mild conditions. The products are liquid while containing at least 25 percent symmetrical triaryl thiophosphate. Colorless and odorless products are prepared.
