Abstract: 1. A PROCESS FOR PREPARING CRYSTALLINE, SUBSTANTIALLY NON-SOLVATED ALUMINUM HYDRIDE WHICH COMPRISES; (A) PROVIDING AN ETHER SOLUTION OF ALUMINUM HYDRIDE, SAID SOLUTION HAVING AN ALUMINUM HYDRIDE/ETHER RATIO OF FROM ABOUT 0.05 TO ABOUT 1 ON A GRAM-MOLE BASIS, AND (B) HEATING SAID SOLUTION UNDER PRESSURE AT A TEMPERATURE OF FROM ABOUT 50 TO ABOUT 85*C. WITHOUT REMOVING SAID ETHER THEREFROM FOR A PERIOD OF TIME SUFFICIENT TO CRYSTALLIZE THE PARTICULATE SUBSTANTIALLY NON-SOLVATED, CRYSTALLINE ALUMINUM HYDRIDE THEREIN AND (C) RECOVERING SAID PARTICULATE SUBSTANTIALLY NONSOLVATED, CRYSTALLINE ALUMINUM HYDRIDE THEREFROM.

Abstract: An aqueous liquor containing oxidizable organic materials is treated in the following manner to oxidize the organics. There is provided in solution, in the organically polluted aqueous liquor, a catalytic quantity of iron ions. The pH of the aqueous liquor is adjusted to 4 or below and then treated with oxygen and light energy having a wave length of 5800 A or less. The principle products of the oxidation process are CO2, water and lower molecular weight organics.
