Tri-n-amyl phosphate (TAP) is a promising extractant for use in fast reactor fuel reprocessing. The effect of diluent on the enthalpy of extraction of uranyl nitrate by tri-n-amyl phosphate was studied in the temperature range 283 K to 303 K employing a number of diluents including isooctane, n-dodecane, cyclohexane and benzene. Except o-dichlorobenzene, all the diluents gave almost comparable enthalpy values. 

The effect of solvent structure on the enthalpy of extraction of americium (III) nitrate was studied using various trialkyl phosphates such as tri-n-butyl phosphate (TBP), tri-isobutyl phosphate, tri-n-amyl phosphate (TAP), tri-isoamyl phosphate and tri-n-hexyl phosphate. The results indicated that the enthalpy of extraction decreased in the order TBP>TsBP>TAP>TiAP THP. This behaviour was in contrast to the variation of the enthalpy of extraction of uranium (VI) with the alkyl carbon stmcture of the trialkyl phosphates reported in literature. 

The above is a general procedure for preparing trialkyl orthophosphates. Similar yields are obtained for trimethyl phosphate, b.p. 62°/5 mm. triethyl phosphate, b.p. 75-5°/5 mm. tri-n-propyl phosphate, b.p. 107-5°/5 mm. tri-Mo-propyl phosphate, b.p. 83-5°/5 mm. tri-wo-butyl phosphate, b.p. 117°/5-5 mm. and tri- -amyl phosphate, b.p. 167-5°/5 mm. The alkyl phosphates are excellent alkylating agents for primary aromatic amines (see Section IV,41) they can also be ua for alkylating phenols (compare Sections IV,104-105). Trimethyl phosphate also finds application as a methylating agent for aliphatie alcohols (compare Section 111,58).

Various organic extractants may be used, including butyl and amyl alcohols, di-isopropyl ether, tri-n-butyl phosphate, and tri-2-ethylhexyl phosphate. The fluoride remains with the calcium chloride solution, from which it may be recovered for sale or disposal. The process was invented in 1957 by A. Baniel and R. Blumberg at Israel Mining Industries, Haifa. 

This is a general method for preparing alkyl phosphates. Using a similar procedure, the w-propyl ester may be obtained in 60-65 per cent yields, the -butyl ester in 40-45 per cent yields, and the n-amyl ester in 60-65 per cent yields, from the corresponding alcohols.2...

Crosslinked PBU [(VeA o) 0-20 kmol/m ] and crosslinked elastomer of butadiene-nitrile rubber SCN-26 [(VeA o) 0.07 kmol/m ] were used in this study. The tests were carried out at 25+0.10 C in the following mixtures n-nonane-tributyl phosphate (TBP), n-hexane-dibutyl phthalate (DBP), n-hexane-dibutyl maleate (DBM), and dioctyl sebacate (DOS)-diethyl phthalate (DEP). A crosslinked elastomer SCN-26 was immersed to equilibrate in amyl acetate-dimethyl phthalate mixture. Liquid phase composition was in range of 5 to 10%. A sol-fraction of samples (plates of 0.9x10 m diameter and in 0.3x10 m thickness) was preliminary extracted with toluene.
