The first three tertiary amines in the aliphatic series were studied by Strecker and Baltes. The authors studied tri-n-butylamine, tri-n-hexylamine, and tri-n-heptyl-amine. Each amine was ozonated at dry ice temperature and treated with picric acid. The tri-n-butylamine oxide picrate readily deposited as crystals on standing. Although the latter two amine oxides formed oily products at first, on long standing in the refrigerator they gave crystals of the amine oxide picrates. The purified amine oxide picrates were analyzed by direct titration with perchloric acid. [Pg.202]

Phase-transfer agents are the most popular catalysts for the Halex reaction with alkaline fluorides. All types of transfer agents have been claimed tetraalkyl-ammonium halides (refs. 34, 48), Aliquat 336 (ref. 49), branched pyridinium halides (eventually supported on a polymer) (refs. 50 to 53), tetraalkylphosphonium chlorides (refs. 42, 54 - 57) or bromides (ref. 12), crown-ethers (refs. 58, 59) eventually associated with Ph4PBr (refs. 43, 60), tris-(dioxa-3,6-heptyl)amine (TDA-1) (ref. 61) or polyethyleneglycols (PEG) (ref. 62). [Pg.272]

The class of aliphatic and aromatic amines is presented by primary (octadecyl, isopropyl and allyloamines), secondary (tributyl, triisopropyl amines) and other amines as well as by benzyl amine, salts of aliphatic amines (diisopropylamine nitrite, octadecylamine salicylate, hexamethylene diamine chromate, ethyl and diethyl amine benzoate, 2-ethyl-hexyl-heptyl amine molybdate), heteroalkylated lower amines (aminoketones, aminoni-triles Cl of Russian grade IFHAN amine alcohols). [Pg.35]
