Sodium Hydrogen Diacetate

Figs. 19 and 20 show the infrared spectra of some acid salts and related crystalline compounds. The spectrum in Fig. 19(a) is from an acid salt of Type B, and it approximates to a superposition of the spectra of free acid and neutral salt. The other spectra are all of Hadzi s T5q>e (ii), which is shown in its starkest form in Fig. 19(c) (sodium hydrogen diacetate) with a window near 950 cm h Potassium hydrogen malonate, a Type A structure, has a similar spectrum (20 (a)). The picoline-N-oxide hemi-hydrobromide (19(d)) is a T5q>e A basic salt Cook s basic salt (Sect. XI) is of pseudo-Type A and gives the spectrum (20(b)). Sodium bicarbonate (20(c)) and potassium hydrogen oxalate (20(d)) are acid sdts of intermediate character (see Sect. XV and XVI A).

Considering that the zero tolerance requirement brought about many problems in terms of export of San Daniele dry cured ham to the USA because of a remote chance that it may be affected by a very low contamination with L. monocytogenes (<10 CFU/g) as it is impossible to completely eliminate it during production or in the finished product, the aim of the work was to produce and validate different methods to eliminate or reduce L. monocytogenes from San Daniele Dry cured ham. The methods used included chemical solutions (1.5% sodium lactate, 1% sodium diacetate, a 1.5%/1.0% sodium lactate/diacetate mixed solution), ionized air, water and ozonised air, hydrogen peroxide solution, essential oils and microbial protective starter (Leuconostoc camosum).

The dimethyl acetal (94) is readily prepared from the 22-aldehyde (93) by direct reaction with methanol in the presence of hydrogen chloride. Ena-mines (95) are formed without a catalyst even with the poorly reactive piperidine and morpholine.Enol acetates (96) are prepared by refluxing with acetic anhydride-sodium acetate or by exchange with isopropenyl acetate in pyridine.Reaction with acetic anhydride catalyzed by boron trifluoride-etherate or perchloric acid gives the aldehyde diacetate. 

The electrochemical oxidation is often more sensitive to the reaction conditions than to the substituents. Platinum electrodes are recommended for methoxylation and the equivalent acetoxylation procedures.290 In acetonitrile buffered by hydrogen carbonate ion, 3,4-diethylfuran affords the 2,5-dihydroxy-2,5-dihydro derivative (84%) and Jones oxidation readily leads to diethylmaleic anhydride in what is claimed to be the best general method for such conversions.291 In unbuffered methanol and under current density control, the oxidation of 2-methylfuran appears to eliminate the methyl group since the product is the acetal-ester 111 also obtained from methyl 2-furoate.292 If sodium acetate buffer is used, however, the methyl group is retained but oxidized in part to the aldehyde diacetate 112 in a... 

To a solution of 1.6 grams of anhydrous hydrogen fluoride in 2.85 grams of tetrahydrofurane and 10 cc of methylene chloride cooled to -60°C was added a solution of 650 mg of the 16,21-diacetate of 6a-fluoro-9p,lip-oxido-S4-pregnene-16a,17a,21-triol-3,20-dione in 20 cc of methylene chloride and the mixture was kept at -10°C for 72 hours. It was then poured into saturated aqueous sodium bicarbonate solution and the organic layer was separated, washed with water, dried over anhydrous sodium sulfate and evaporated. The... 

The lower-melting dimethylene compound was resistant to periodate treatment and its ditosyl ester did not participate in the sodium iodide exchange reaction thus it was probable that the diacetal was of the 1,2,4,6-, 1,3,4,6- or 1,3,5,6-type. For theoretical reasons the authors48 favored tentatively the 1,3 4,6-pattern. Since the other dimethylene-D-talitol (m. p. 261-262°) did not react with periodate and since its ditosyl ester could be converted into a didesoxy-dimethylene-hexitol by sodium iodide exchange and hydrogenation, it was designated as 2,3,4,5-dimethyl-...
