Inventor: SHIMADA KEIZO
IPC: D01F6/60
Filed: 1986-01-09
Abstract: PURPOSE:In a polar amide solvent containing an alkali metal chloride, terephthaloyl chloride is added stepwise to p-phenylenediamine to effect polycondensation reaction, then a precipitating agent is added, and the precipitate is crushed to give the titled fiber of high processability, giving high-duration paper.

Title: Diluent for extractant for use in nuclear fuel reprocessing
Inventor: KOMA YOSHIKAZU
IPC: G21C19/46
Filed: 1994-01-11
Abstract: PURPOSE:To improve the efficiency of operation in the extraction of tri-, tetra-, and hexavalent metals from a highly radioactive liquid waste with a solvent containing CMPO by using a specific diluent to prevent the solvent from separating into two phases without reducing extraction efficiency. CONSTITUTION:2-Methylundecane, 3-methylundecane, or 2,2,4,6,6- pentamethylheptane is used as a diluent for inhibiting a solvent containing CMPO from separating into two phases upon contact with a high-concentration aqueous solution of metals. Of these compounds, 2-methylundecane has a remarkable effect. An extractant comprising a mixture of the solvent with the diluent is contacted with a highly radioactive liquid waste to extract tri-, tetra-, and hexavalent metals, and the extract is subjected to back extraction with, e.g. diluted nitric acid to separate the intended metal elements from the extractant.
