Ammonium Compounds Rule C-816 . A Carbosieve S column was utilized for CO and CO2 analysis, with a programmed increase in oven temperature from 40 to 240 °C (TCD). The acetylenic alcohols (423) have found application for coal flotation 〈85URP1198074〉. Molecular Formula. The amidinium salts (152) are useful for the synthesis of imidazoles. Derivatized anionic gums and compositions thereof are disclosed. n = positive whole number R 1, R 2, R 3, and R 4 could be hydrogen atoms, alkyl groups, aryl groups, or any combination thereof. Ammonium nitrate is a dangerous solid and should be handled with great care. In liquid fabric softeners, the chloride salts are often used. Unless otherwise specified, the residence time was equal to 3.6 s. The reactor outlet was kept at 200 °C, to prevent product condensation and methacrylic acid polymerization. Mixed with organic matter, ammonium nitrate is used as a substitute for dynamite in open-pit mining. The precipitate was dried at 120 °C overnight (with solvent evaporation), and then calcined up to 350 °C in static air, for 6 hours. They become ions when dissolved in water. Many simple ammonium salts are very soluble in water, exceptions being ammonium perchlorate (NH4ClO4) and ammonium hydrogen carbonate (NH4HCO3). The benzodioxole carboxylic acid (424) has been used as a chiral derivatizing agent to allow determination of the ee of alcohols and amines by NMR and HPLC 〈89TL5277〉 and the analogue (425) has been used for this purpose 〈92JAP04346982〉 and as a derivatizing agent for TLC resolution of amino acids 〈93TA1431〉.
