SUMMARY CONCLUSIONS OF THE SIAR Human Health The toxicology database for tributyl phosphate (TBP) is large and well documented. There are adequate data with which to evaluate the potential hazard to human health of this compound. Acute oral toxicity values in rodents range from 1390 to 3350 mg/kg-bw in rats and from 400 to 1240 mg/kg-bw in mice. A rat six-hour LC50 of > 4.2 mg/L (highest dose tested) was reported. Dermal studies exist in rabbits (LD50s of >3100 mg/kg-bw and > 10,000 mg/kg-bw) and in guinea pigs (LD50 of 9700 – 19,400 mg/kg-bw).

The method involves the separation of TBP and shall solT(SST) from 30% TBP/SSP mixture by thorium nitrate extraction leading to the formation of a heavy phase (Third phase) which contains osssntially TBP. The equilibrium experiments revsaled that by utilizing Thorium feeds of concentrations above 525 g/L. in water at 111 ratio, a 30% TBP/SST mixture can be effectively separated into TBP and SST fractions with light SST phase having about 3% TBP, Using single stage mixer settler experiments, the feasibility of continuous separation of the three phases was assessed. Since there is a tendency for the degraded products of the diluent to seek the TBP phase, additional treatment steps would be necessary for their removal if the TBP is to be reused.
