Title: Recovery of uranium and/or plutonium from solution
Inventor: STEVENSON DAVID GORDON
IPC: C22B60/04
Filed: 1964-03-20
Abstract: Uranium is recovered by a continuous process comprising adding a base to an acidic aqueous solution of a salt of uranium in a precipitation zone in te presence of an aliphatic C10-C5 monocarboxylic acid to form a precipitate of a compound of uranium, said monocarboxylic acid being present in amount sufficient to form a complex ion with the metal ions but insufficient to precipitate a salt of said monocarboxylic acid with the metal ions in the absence of said base, and withdrawing the precipitate from the precipitation zone. The process may be applied to plutonium (see Division G6) and to co-precipitation of U and Pu.  The base is preferably NH4OH and the acid may be 0.1 to 5N acetic acid, in amount sufficient to form the ion (UO2Ac3]-.  The consistency of the precipitate of ammonium diurate is improved by adding ammonium acetate to NH4OH which results in faster precipitation and less filtration resistance.

Title: Purification of perchloroethylene
Inventor: SHELTON ROBERT DUKE
IPC: C07C17/38
Filed: 1958-04-18
Abstract: A process for the separation of perchloroethylene from a composition containing also trichloroethylene and symmetrical tetrachloro ethane comprises subjecting the composition to a first distillation, rejecting the major portion of the trichloroethylene as the low boiling fraction and collecting the remainder of the composition comprising mainly perchloroethylene and symmetrical tetrachloroethane and subjecting this remainder to a second distillation, rejecting substantially all of the symmetrical tetrachloroethane as distillation bottoms, and collecting the low boiling fraction from the second distillation and subjecting this fraction to a third distillation and collecting purified perchloroethylene as the bottoms product therefrom.  Preferably any inorganic compounds which may be present are removed before the distillations commence.  Distillation may be effected at increased or reduced pressure, but atmospheric pressure is preferred.  In an example, a mixture comprising trichloroethylene 68.0%, perchloroethylene 23.5%, and tetrachloroethane 6.8% was fed at 87.8 DEG  C. to the 24th plate of a 36 theoretical plate column and distilled to give a top fraction containing 99.86% and a bottom fraction comprising perchloroethylene 84.6% and tetrachloroethane 15.9% which was redistilled in a column with a feed temperature of 123 DEG  C., giving an overhead product containing 99.7% of perchloroethylene.  This product was redistilled using a temperature of 121 DEG  C. at the feed plate and a top temperature of 116 DEG  to 120 DEG  C. to produce a bottoms fraction which is pure perchloroethylene.  In a modified process in which the trichloroethylene constitutes only a minor quantity of the initial composition, the first and second distillations are consolidated into one.  Specifications 468,921, [Group IV], and 793,205, [Group IV (b)], are referred to.
