Calcium benzoate

D C and external D C lakes These lakes are usually manufactured by precipitating a soluble dye onto an approved substrate. In the case of D C colors, the substrate may be alumina, blanc fixe, gloss white, titanium dioxide, zinc oxide, talc, rosin, aluminum benzoate, calcium carbonate, or any combination of these materials.

Similarly, androstane-5a,6a,17)S-triol 6-tosylate 17-benzoate (115b) is converted to 17)S-hydroxy-6)S-methyl-10(5 6)SH)flZ)en-androstan-5-one benzoate (116b) on treatment with calcium carbonate in dimethylformamide. Similar treatment of 10-methyldecalin-l,9-diol 1-tosylate (121) gives 10-methylbicyclo[5.3.0]decan-l-one (122). 

Reactions.—i. Make a neutral solution of ammonium benzoate by adding excess of ammonia to benzoic acid and boiling until neutial. To different poitionsadd solutions of calcium chloi ide, ferric chloride, silver nitrate and lead acetate and note the results. 

It is prepared artificially by the distillation of calcium benzoate, or by the condensation of benzene and benzoyl chloride in the presence of aluminium chloride. 

Benzophenone has been prepared by the distillation of calcium benzoate,1 by the action of benzoyl chloride on benzene in the presence of aluminium chloride,2 by the action of phosgene on benzene in the presence of aluminium chloride,3 by the action of carbon tetrachloride on benzene in the presence of aluminium chloride followed by hydrolysis.4... 

Calcium propionate is used in bakery products as a mold inhibitor. Propionates prevent microbes from producing the energy they need, just as benzoates do. However, unlike benzoates, propionates do not require an acidic environment. 

Fumaric acid is used to lower the pH (make something more acidic, which makes it taste more sour). This helps certain antimicrobial agents such as sodium benzoate and calcium propionate work more effectively. Fumaric acid also kills bacteria. 

The presence of water results in very rapid saponification of ethyl benzoate. Dimethyl sulfoxide (Crown Zellerbach Corp.) may be dried by stirring with calcium hydride for 4-8 hours, followed by distillation under reduced pressure at 80-90° without filtration. Commercial 2-butyl alcohol and ethyl benzoate are conveniently dried by stirring for 2-4 hours with calcium hydride followed by filtration.

Several types of corrosion inhibitors have been investigated in the last 20 years [53-55] these include calcium and sodium nitrites, sodium benzoate, sodium/potassium chromate, sodium salts of silicates and phosphates, stannous chloride, hydrazine hydrate, sodium fluorophosphate, permanganate, aniline and related compounds, alkalis, azides, ferrocyanide, EDTA and many chelating compounds. However, in terms of field practice and research data, nitrite-based compounds occupy a dominant position. 

The most widely used anodic inhibitors are calcium and sodium nitrite, sodium benzoate and sodium chromate. With the exception of calcium nitrite, no other chemical is available in North America as a proprietary product. Nitrites have been used in the USA for more than 14 years and for nearly 40 years in Europe. Calcium nitrite is marketed as a non-chloride accelerator, as well as a corrosion inhibitor. For 25-30% solids in solution, dosage rates range from 2 to 4% by weight of cement depending on the application [50]. Calcium nitrite has been used in bridges, parking and roof decks, marine and other prestressed concrete structures that are exposed to chloride attack. 

Sodium benzoate has been used singly in concrete structures exposed to severe corrosion attack and also in combination with sodium nitrite in cement slurries to paint on steel reinforcement before embedment in concrete [65, 66]. Work done by Lewis et al. showed that concrete to which 2% benzoate was added produced setting times that were similar to control concretes, but the compressive strengths decreased by about 40% [66, 67]. Lewis et al. [66] however have concluded that sodium benzoate has a more persistent inhibitory effect than calcium nitrite. 

Methyl />-acetylbenzoate has been prepared by the esterification of -acetylbenzoic acid with methanol in the presence of hydrogen chloride,6 by the hydrogenation of methyl -trichloro-acetylbenzoate in the presence of a palladium on calcium carbonate catalyst,6 and by the air oxidation of methyl / -ethyl-benzoate.4...
