Calcium acetate oxide

Buffer solution, double strength - add to 4.5 I water, 400 g oven-dried calcium acetate, 80 g 4-nitrophenol and 6 g of light magnesium oxide. [Safety note 4- (or para-) nitrophenol may cause eye irritation or irreversible eye injury, and may be harmful by absorption through skin or ingestion.] Heat the mixture to dissolve the solids and dilute to 5 I. Filter if the solution is not clear. The pH of this solution should lie between 6.9 and 7.1 adjust by the addition of hydrochloric acid or magnesium oxide as necessary.

In tonnage production, acetaldehyde may be manufactured by (1) the direct oxidation of ethylene, requiring a catalytic solution of copper chloride plus small quantities of palladium chloride, (2) the oxidation of ethyl alcohol with sodium dichromate, and (3) the dry distillation of calcium acetate with calcium formate. 

Benzalacetone has been obtained in small yield by drv distillation of a mixture of calcium acetate and calcium cinnamate (1) by heating the sodium derivative of cinnamaldehyde with methyl iodide (2) by heating cinnamaldehyde and methyl alcohol with zinc chloride (2) by heating acetone and benzaldehyde with acetic anhydride or zinc chloride (3). It is also formed when styrene and acetyl chloride are condensed by means of stannic chloride and the product is treated with diethylaniline (4) and when the vapors of cinnamic acid and acetic acid are passed together over ferric oxide at 470-490° (5). The only practical method, however, consists in condensing benzaldehyde and acetone by means of dilute aqueous alkali (6). 

In the model mixture studies calcium acetate was observed to react with pyrite at 750° and 1000°C to generate anhydrite XRD peaks of greater intensity than those observed for the system of calcite reacting with pyrite (Table II, Systems A and B). Sulfur fixation by calcium released from calcium acetate by pyritic sulfur was greater than in the calcite case probably due to the similar tanperatures at which calcium acetate decomposes and pyrite oxidizes (400° to 500°C). Calcite, on the other hand, does not decompose until higher temperatures (900°C) therefore the calcium necessary to form anhydrite is not as readily available. Most of the SO2 formed by oxidation of pyrite would be lost to the atmosphere by the time calcite decomposes. 

In system F calcite was used as a calcium source for the formation of gehlenite. The reaction did not proceed as completely as with calcium acetate, as inferred from two observations 1) some of the calcium remained as calcium oxide upon decomposition of... 

Acetic acid, unlike formic acid, cannot be oxidized easily. Thus, acetates can be reacted with H2S04 to produce acetic acid. As mentioned earlier, acetate produced by the condensation of wood can be precipitated as calcium acetate using limewater. Methanol and acetone are evaporated from the mixture and if the remaining calcium acetate is reacted with H2S04, 99.5% pure acetic acid is obtained.

Concerning the rise in importance of acetone, Northrop, Ash, and Morgan say, Acetone was one of the substances for which the war created a greatly increased demand. It was needed by all the allies for the dope used on airplane wings and by the English in addition for the manufacture of cordite. The ordinary source of acetone, the dry distillation of wood, proved quite inadequate to supply the qualities needed. It became necessary therefore to develop some new method for the production of acetone. Large quantities were made from calcium acetate which was in turn produced from acetic acid obtained by the oxidation of alcohol. The expense of this process, however, rendered it impracticable. It seemed important, therefore, under these conditions, to attempt the development of a direct fermentation process for the production of acetone, inasmuch as such a method, if successfully developed, would furnish aoetone in practically unlimited quantity and at a low cost. ... 

The salt obtained by evaporating the solution to dryness is called gray acetate of lime. Commercial acetic acid is obtained from the calcium acetate so prepared by distilling with concentrated hydrochloric acid in copper stills. The acid is a slightly-colored liquid which contains about 50 per cent of acetic acid. It may be further purified by redistilling over a little potassium bichromate, which oxidizes some of the impurities, and by filtering through charcoal. 

Considerable interest has been shown in analytical methods for the determination of algin (68, 72, 78, 101, 158, 171, 21A, 292). Improvements were made in the Lefevre-Tollens hydrochloric acid decarboxylation method by McCready, Swenson, and Maclay (135, 143) to make it more adaptable to routine determinations. Kenyon and coworkers (148, 262, 271, 272) in a series of articles compared various methods for the determination of the carboxyl content of sugar acids. These included the calcium acetate-acetic acid method, the potentiometric titration method in the presence of sodium bromide, decarboxylation and determination of the isolated furfural. Percival and Ross (70, 187) described improvements in the colorimetric carbazole determination of algin. New analytical methods include the oxidation of algin with cerium sulfate (W) and Perlin s (188) recent report of the quantitative thermal decomposition of algin at 255 C.

Grosshardt et al. prepared a series of furan based polyesters, by reacting FDCA dimethyl ester with 1,3-propanediol, 1,6-hexanediol, 1,12-dodecanediol and 1,18-octadecanediol, using calcium acetate and antimony(III) oxide as catalysts [47]. Molecular weights and thermal properties were determined for all polyesters and are summarized in Table 9.6.

Slosarczyk et al. have used a wet method to obtain carbonated HAp powders [56, 57]. Calcium oxide (CaO), calcium nitrate, calcium tetrahydrate [Ca(N03)2-4H20] or calcium acetate [Ca(CH3COO)2-H20] were used as the calcium source. As the phosphorous source, phosphoric acid (H3PO4) or di-ammonium phosphate [(NH4)2HP04] were used. The molar ratio of Ca P was 1.67. Ammonium bicarbonate (NH4HCO3) or sodium bicarbonate (NaHCOs) were used as reactants to introduce groups. Biological apatites in natural bone, dentin, and enamel...
