    摘要: The present invention is directed to a method of preparing an inorganic-alkali metal salt of the formula:ZYwherein Z is an alkali metal selected from the group consisting of lithium and sodium, and wherein Y is an inorganic radical selected from the group consisting of SCN, CN, CNS, OCN, Br, I, Cl, NO.sub.2, NO.sub.3, ClO.sub.4, ReO.sub.4, and CF.sub.3 SO.sub.3. The method involves the reaction of a nitrogen-containing compound of the formula:QHYwherein Q is selected from the group consisting of specified nitrogen-containing groups, and wherein H is hydrogen and Y is as defined above, with an alkali metal compound of the formula:ZXwherein Z is defined above and wherein X is selected from the group consisting of hydrogen, specified nitrogen-containing radicals, and specified organic radicals. The reaction is carried out in ether solvent. In a preferred embodiment, Q is NH.sub.3 and X is hydrogen.

    摘要: THE YIELD OF CYANURIC CHLORIDE IS INCREASED AND THE LIFE OF AN ACTIVATED CHARCOAL CATALYST USED IN PREPARING CYANURIC CHLORIDE BY CONTACT OF CYANOGEN AND CHLORINE IN THE GAS PHASE AT A TEMPERATURE OF FROM ABOUT 350*C. TO ABOUT 750*C. IS CONSIDERABLY LENGTHENED BY PRETREATMENT OF THE ACTIVATED CHARCOAL CATALYST FOR REMOVAL THEREFROM OF METAL COMPOUNDS, PREFERABLY WITH A METALSOLUBILIZING ACID SUCH AS AQUEOUS HYDROCHLORIC ACID, FORMIC ACID, ACETIC ACID OR DILUTE NITRIC ACID.
