Ammonium lactate

Ammonium lactate [34302-65-3] ia coaceatrated aqueous solutioas has beea coaverted to ammonia and the ester by alcoholysis at temperatures ranging from 100—200°C usiag a variety of alcohols and water entrainers, such as toluene. Ester yields ranging from 50—80% were obtained. This method has also been suggested as a recovery and purification method from impure solutions of lactate (29). However, a considerable amount of the lactate is not converted to the recoverable ester and is lost as lactamide (6).

In a further method [67] for the determination of ammonium lactate extractable (i.e. available) phosphorus in soils, the sample 5g is extracted with 100ml acidic ammonium lactate and then phosphate determined by flow-injection analysis using the stannous chloride method [68].

Lactose is readily fermented by lactic acid bacteria, especially Lactococcus spp. and Lactobacillus spp., to lactic acid, and by some species of yeast, e.g. Kluyveromyces spp., to ethanol (Figure 2.27). Lactic acid may be used as a food acidulant, as a component in the manufacture of plastics, or converted to ammonium lactate as a source of nitrogen for animal nutrition. It can be converted to propionic acid, which has many food applications, by Propionibacterium spp. Potable ethanol is being produced commercially from lactose in whey or UF permeate. The ethanol may also be used for industrial purposes or as a fuel but is probably not cost-competitive with ethanol produced by fermentation of sucrose or chemically. The ethanol may also be oxidized to acetic acid. The mother liquor remaining from the production of lactic acid or ethanol may be subjected to anaerobic digestion with the production of methane (CH4) for use as a fuel several such plants are in commercial use. 

Whey permeate may also be fermented anaerobically to fuel gas. Studies have also been reported on the production of ammonium lactate by continuous fermentation of deproteinized whey to lactic acid followed by neutralization with ammonia. Conversion of whey and whey permeate to oil and single-cell protein with strains of Candida curvata and Trichosporon cutaneum have been examined. Production of the solvents n-butanol and acetone by Clostridium acetobutylicum or C. butyricum is under investigation in New Zealand. Whey permeate also has potential for citric acid and acrylic acid manufacture. Extracellular microbial polysaccharide production from whey permeate has... 

A quick separation of 152Eu — 241 Am mixture with ammonium lactate as eluant has been described [77]. The influence of the flow rate of the eluant and the particle size of the ion exchanger has been studied. Katex KP-1, a polystyrol cation exchange resin was used to separate 152Eu, 154Eu and 147Pm mixture with success [75].

Urea is a hydrating agent (a hydrotrope) used to treat scaling conditions such as psoriasis, ichthyosis, and other hyperkeratotic skin conditions. Applied in a water-in-oil vehicle, urea alone or in combination with ammonium lactate hydrated stratum corneum and improved barrier function when compared to the vehicle alone in human volunteers in vivo [45], Urea also has keratolytic properties, usually when combined with salicylic acid for keratolysis. The somewhat modest penetration-enhancing activity of urea probably arises from a combination of increasing stratum corneum water content (water is a valuable penetration enhancer) and through the keratolytic activity. 

Treatment of xerosis on the plantar surface of the feet for two weeks gave more pronounced improvement in skin roughness, fissures, and dryness by a 40% urea cream (Carmol 40) than from a 12% ammonium lactate lotion (Lac-Hydrin).40 No change in transepidermal water loss (TEWL) was noted from urea-treatment. Both therapies showed sustained benefit during the next two weeks. Furthermore, a cream containing 10% urea and 4% lactic acid provided faster and better improvement with significantly less xerosis regression in patients with diabetes.41...
