Dinitrogen tetraoxide reacts explosively between —32° and — 90°C with propene, 1-butene, isobutene, 1,3-butadiene, cyclopentadiene and 1-hexene, but 6 other unsaturates failed to react [1]. Reaction of propene with the oxide at 2 bar/30°C to give lactic acid nitrate was proceeding in a pump-fed tubular reactor pilot plant. A violent explosion after several horns of steady operation was later ascribed to an overheated pump gland which recently had been tightened. A similar pump with a tight gland created a hot-spot at 200°C [2],... 

CH3CH(0H)C(0)0Et. A colourless liquid with a pleasant odour, b.p. 154 C. Manufactured by distilling a mixture of ( )-lactic acid, ethanol and benzene in the presence of a little sulphuric or benzenesulphonic acid. It is a solvent for cellulose nitrate and acetate and also for various resins. Used as a lacquer solvent. 

In similar work, Sturgeon et al. [125] compared direct furnace methods with extraction methods for cadmium in coastal seawater samples. They could measure cadmium down to 0.1 pg/1. They used 10 pg/1 ascorbic acid as a matrix modifier. Various organic matrix modifiers were studied by Guevremont [116] for this analysis. He found citric acid to be somewhat preferable to EDTA, aspartic acid, lactic acid, and histidine. The method of standard additions was required. The standard deviation was better than 0.01 pg/1 in a seawater sample containing 0.07 pg/1. Generally, he charred at 300 °C and atomised at 1500 °C. This method required compromise between char and atomisation temperatures, sensitivity, heating rates, and so on, but the analytical results seemed precise and accurate. Nitrate added as sodium nitrate delayed the cadmium peak and suppressed the cadmium signal.

Two methods of prepn are listed in Ref 3 a)By esterification of lactic acid with ethanol and b)By combining acetaldehyde with hydrocyanic. acid to form acetaldehyde cyanohydrin, and this is treated wi th ethanol HC1 to ethyl lactate. Used as a solvent for cellulose acetate and nitrate, other cellulose esters, resins, lacquers, paints and enamels Refs l)Beil 3, 264, 267, 280,(102,109) ...

Changing the composition of the aqueous phase (1 mol L 1 lactic acid + 0.05 mol L 1 DTPA or HN03 3 mol L ) has a negligible effect on the global yields of HDEHP decomposition products in solution. However, substantial changes have been observed in the gaseous composition in the presence of lactic acid (the yields of H2 doubled and C02 appeared, whereas 02 completely disappeared), and the amount of oxidation products increased, contrary to nitration derivatives, which decreased (12). 

During the early stages of fermentation the growth of harmful bacteria is checked, in the past lactic acid was used, but now antiseptics, to which the selected yeast has been acclimatized, are employed. The following substances have been used bismuth nitrate, calcium bisulphite, hydro-fluoric acid, ammonium fluoride, the latter being now most in favour. 

LACTIC ACID, ETHYL ESTER (97-64-3) CjHioOj Forms explosive mixture with air [explosion limits in air (vol %) 1.5 to 11.4 flashpoint 115°F/46°C cc autoignition temp 752°F/400°C Fire Rating 2]. Contact with strong oxidizers may cause fire and explosions. Incompatible with nitrates alkalis or acids (either can generate high heat). Contact with alkali metals and hydrides liberates flammable hydrogen gas. On small fire use dry chemical, alcohol-resistant foam, or COj extinguishers. LACTOBARYT (7727-43-7) see barium sulfate.
