Transformation of these species defines the formation of all the secondary products belonging to two series (due to two different substitutes in the aromatic rings) of acetophenones, benzoic acids, benzaldehydes and phenols. In our earlier publications on avobenzone aquatic chlorination (Kalister et...
A product of dehydrogenated (metabolized) alcohol, hence the name. Aldehydes cause most of the toxic effects of bibulous overindulgence (hangover). Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005 al·de·hyde (al'dĕ-hīd) ...
1.(Elements & Compounds) a colourless or yellowish oily liquid, miscible with water, used in the manufacture of rubber accelerators, as an organic solvent, in perfume, and as a hypnotic and sedative. Formula: CH3CHOHCH2CHO. Systematic name:3-hydroxybutanal ...
It has often been reported that complete conversion of benzaldehyde to PAC is not possible in whole cell systems because of the formation of by-products, namely benzyl alcohol and benzoic acid (refs. 15,16,21,25,26,27,28,29). Benzyl alcohol is the main by-product of the PAC process ...

Iron-based hydrotalcite catalysts such as MnFe, CoFe, CeFe, NiFe and MgFe as well as their single monoxides were screened for selective oxidation of styrene to obtain benzaldehyde and styrene epoxide. The catalysts were characterized by X-ray diffraction, ATR-FTIR and Raman spectroscopy, chemical...
After extensive condition optimization using benzaldehyde 1a and S-(fluoromethyl) benze- nesulfonothioate (PhSO2–SCH2F) 2a as the model substrates (Supplementary Table 1), we found that neutral eosin Y (4 mol%) in tert-butanol (tBuOH) under blue light (18 W, 470 nm LED) irradiation ...
Synthesis of 4-[2-(4,6-diamino-[1,3,5]triazin-2-yl)-vinyl]-benzaldehyde. To 107.2 g (800 mmol) of benzene-1,4-dicarboxaldehyde suspended in 450 mL methanol was added with stirring 294.0 g of 31% aqueous sulfuric acid (50 mL of concentrated sulfuric acid was added slowly to 200 mL...
wherein said aqueous solution of a low- or medium-boiling secondary component comprises a compound selected from the group consisting of acetic acid, maleic acid, fumaric acid, formaldehyde, propionic acid, benzaldehyde, diacrylic acid, hydroxypropionic acid, benzoic acid, diphenyl ether, and mixtures...
surface of the film, which has been subjected to an acid treatment, shows a contact angle to water of 70° or less; and a film-forming process which comprises coating said topcoating composition onto a substrate to form a film, followed by treating the surface of the film with an acid....
