Ammonium acetate chloride

From this ranking, quaternary ammonium acetates, chlorides, nitrates, and bromides are apparently more soluble in organic solvents such as aqueous /-butyl alcohol than are the corresponding quaternary ammonium hydroxides. Thus these quaternary ammonium salts would be readily extracted into the organic phase. In addition, a high concentration of...

Substituents in the 6-position (cf. 267) show appreciable reactivity. 6-Bromo-as-triazine-3,5(2j, 4j )-dione (316) undergoes 6-substitution with secondary amines or hydrazine, with mercaptide anions or thiourea (78°, 16 hr), with molten ammonium acetate (170°, 24 hr, 53% yield), and with chloride ion during phosphorous oxychloride treatment to form 3,5,6-trichloro-as-triazine. The latter was characterized as the chloro analog of 316 by treatment with methanol (20°, heat evolution) and hydrolysis (neutral or acid) to the dioxo compound. The mercapto substituent in 6-mercapto-as-triazine-3,5(2iI,4if)-dione is displaced by secondary... 

Either the Mohr titration or the adsorption indicator method may be used for the determination of chlorides in neutral solution by titration with standard 0.1M silver nitrate. If the solution is acid, neutralisation may be effected with chloride-free calcium carbonate, sodium tetraborate, or sodium hydrogencarbonate. Mineral acid may also be removed by neutralising most ofthe acid with ammonia solution and then adding an excess of ammonium acetate. Titration of the neutral solution, prepared with calcium carbonate, by the adsorption indicator method is rendered easier by the addition of 5 mL of 2 per cent dextrin solution this offsets the coagulating effect of the calcium ion. If the solution is basic, it may be neutralised with chloride-free nitric acid, using phenolphthalein as indicator. 

Prolonged heating of 2-butoxy-3//-azepine with ammonium carbonate in methanol produces 3H-azepin-2-amine in excellent yield.79 Lesser yields (50-55%) of the amine are also obtained from 2-(heptyloxy)-3//-azepine using ammonium acetate or ammonium chloride as the animating agent.79,229... 

Aroylation of 3-arylhydrazonoisatin with aroyl chlorides gave 1043, which cyclized with ammonium acetate to give [1,2,4]triazino[5,6-A>]indole 1044 (92MI1). Derivatives of 1045 were prepared (92MI1). Cyclocondensation of 5-ethyl-3-hydrazino-5/f[l,2,4]triazino[5,6-b]indole 165 with succinic anhydride in acetic acid gave pyridazinedione derivative 1046 (90MI7) (Scheme 197).

Ethylbenzoic acid was converted to the acid chloride, which was treated with AICI3 and benzene to give 4-ethylbenzophenone in 90% yield overall. Condensation with ethyl cyanoacetate afforded ethyl 4-ethyl-a-cyano-B-phenylcinnamate as an essentially 50/50 mixture of the Z- and E-isomers. The yield of the condensation was highly sensitive to reaction conditions, and was optimized at 75% with portionwise addition of the ammonium acetate catalyst. Bromination and dehydrobromination as described earlier then completed the preparation. The overall yield of ethyl 4-vinyl-a-cyano-p-phenylcinnamate was 20%. 

Azolo[1,5]naphthyridines. Imidazonaphthyridines can be prepared by the reaction of ammonium acetate with appropriately substituted naphthyridinium salts. For example, reaction of the ketone 236 in acetic acid with iron(m) chloride produces the tetracycle 237 <2001AJC105> (Equation 64). 

Imidazo[2,l- ][l,7]naphthyridines can be prepared by reaction of the ketonaphthyridinium salt 300 with ammonium acetate and iron(m) chloride at high temperature (Equation 102) <2001AJC105>. Reaction of the />m-fused [2,7]naphthyridine 301 with benzylamine or 2-phenylethylamine in the presence of silica gel gives a pentacyclic imidazonaphthyridine 302 (Equation 103) <2001H(54)721>. 

Cr-ZSM-5 catalysts prepared by solid-state reaction from different chromium precursors (acetate, chloride, nitrate, sulphate and ammonium dichromate) were studied in the selective ammoxidation of ethylene to acetonitrile. Cr-ZSM-5 catalysts were characterized by chemical analysis, X-ray powder diffraction, FTIR (1500-400 cm 1), N2 physisorption (BET), 27A1 MAS NMR, UV-Visible spectroscopy, NH3-TPD and H2-TPR. For all samples, UV-Visible spectroscopy and H2-TPR results confirmed that both Cr(VI) ions and Cr(III) oxide coexist. TPD of ammonia showed that from the chromium incorporation, it results strong Lewis acid sites formation at the detriment of the initial Bronsted acid sites. The catalyst issued from chromium chloride showed higher activity and selectivity toward acetonitrile. This activity can be assigned to the nature of chromium species formed using this precursor. In general, C r6+ species seem to play a key role in the ammoxidation reaction but Cr203 oxide enhances the deep oxidation. 

Various chromogenic reagents have been used for the spectrophotometric determination of boron in seawater. These include curcumin [108,109], nile blue [110], and more recently 3,5 di-tert butylcatechol and ethyl violet [111]. Uppstroem [108] added anhydrous acetic acid (1 ml) and propionic anhydride (3 ml) to the aqueous sample (0.5 ml) containing up to 5 mg of boron per litre as H3BO3 in a polyethylene beaker. After mixing and the dropwise addition of oxalyl chloride (0.25 ml) to catalyse the removal of water, the mixture is set aside for 15-30 minutes and cooled to room temperature. Subsequently, concentrated sulfuric-anhydrous acetic acid (1 1) (3 ml) and curcumin reagent (125 mg curcumin in 100 ml anhydrous acetic acid) (3 ml) are added, and the mixed solution is set aside for at least 30 minutes. Finally 20 ml standard buffer solution (90 ml of 96% ethanol, 180 g ammonium acetate - to destroy excess of protonated curcumin - and 135 ml anhydrous acetic acid diluted to 1 litre... 

Anthrapyrimidine and its substituted derivatives are obtained by condensation of 1-aminoanthraquinone (or its derivatives) with formamide or aqueous form-aldehyde/ammonia in the presence of an oxidant, such as ammonium vanadate or m-nitrobenzosulfonic acid. A newly developed, more simple route proceeds via formamidinium chloride, which is prepared from 1-aminoanthraquinone with di-methylformamide and thionyl chloride or phosphorus oxychloride. Cyclization in a solvent in the presence of ammonium acetate affords the desired product ... 

A good method for the preparation of acetamide is to pass ammonia gas into an ethereal solution of acetic anhydride, evaporate the ether and extract the residual mixture of ammonium acetate and acetamide with benzene in an extraction apparatus (Fig. 25). The salt remains undissolved. Amides can also be prepared by the action of ammonia on acid chlorides and esters.
