The anaerobic metabolism of marginally lethal levels of [13C]formaldehyde by Escherichia coli (K12, MU352, CRB, and CR63) was followed in vivo by 13C NMR. The products include 1, 2-propanediol. Under aeration, the 1, 2-propanediol is converted to hydroxyacetone. The hydroxyacetone is reconverted to 1, 2-propanediol when aeration is stopped. The process can be cycled by varying the rate of aeration.Key words: hydroxyacetone, 1, 2-propanediol, Escherichia coli, production.

An Ni/SiO2 catalyst was synthesized by the deposition-precipitation method and used in a mild hydrotreatment process.

The reaction of aqueous glycerol over a series of ceria catalysts is investigated, to produce bio-renewable methanol. Product distributions were greatly influenced by the reaction temperature and catalyst contact time. Glycerol conversion of 21% was achieved for a 50 wt.% glycerol solution, over CeO2 (8 m2 g−1) at 320 °C. The carbon mass balance was &gt;99 % and the main product was hydroxyacetone. In contrast, at 440 °C the conversion and carbon mass balance were &gt;99.9 % and 76 % respectively. Acetaldehyde and methanol were the major products at this higher temperature, as both can be form

Abstract. Gaseous and particulate semi-volatile carbonyl compounds were determined every three hours in the atmosphere of Mount Tai (elevation, 1534 m) in the North China Plain during 2–5, 23–24 and 25 June 2006 under clear sky conditions. Using a two-step filter cartridge in a series, particulate carbonyls were first collected on a quartz filter and then gaseous carbonyls were collected on a quartz filter impregnated with O-benzylhydroxylamine (BHA). After the two-step derivatization with BHA and N,O-Bis(trimethylsilyl)trifluoroacetamide (BSTFA), carbonyl derivatives were measured using a gas

Abstract:
In this study, a set of enantiomerically pure aziridines bearing a phosphine oxide moiety were prepared in high yields and tested as chiral catalysts in the direct asymmetric Mannich reaction of hydroxyacetone, an amine (p-anisidine), and various aromatic aldehydes. The appropriate Mannich adducts were formed in chemical yields from moderate to good with a high level of enantio- and diastereoselectivity. The best results were obtained using the catalysts bearing a free NH-aziridine subunit.

Abstract:
N-alkylated C2-symmetric amino acid amide derivatives were shown to catalyse the Michael addition of 2-hydroxy-1,4-napthoquinone to β-nitrostyrene, achieving a maximum ee of 44%. The corresponding trifluoroacetic acid salts also catalysed the aldol reaction between 4-nitrobenzaldehyde and hydroxyacetone, leading to the formation of predominantly syn-aldol products in up to 55% ee. Aspects of the solvent dependence of the aldol reaction and the H-bonding of the catalyst were investigated.

Abstract:
Abstract Hydroxyl radicals from the radiolysis of N2O/O2 (4:1)-saturated aqueous solutions of acetone (10−3 mol dm −3) react with the solute by H-abstraction thereby forming acetonyl radicals. As shown by pulse radiolysis, the acetonyl radicals rapidly add oxygen (k = 3 x 109 dm3mol−1s−1) thereby forming acetonylperoxyl radicals which decay by second-order kinetics (2 k = 8 x 108 dm3mol−1s−1). Under steady-state radiolysis conditions (0.24 Gy s−1) the products (G values in parentheses) are methylglyoxal (2.5), hydroxyacetone (0.5), form aldehyde (1 .6), acids (1 .7), carbon dioxide (0 .5), org
