0000006396 00000 n While it is commonly employed as a commercial food flavourant (almond flavour) or industrial solvent, benzaldehyde is used chiefly in the synthesis of other organic compounds, ranging from pharmaceuticals to plastic additives. This glycoside breaks up under enzyme catalysis into benzaldehyde, hydrocyanic acid and two molecules of glucose. Create: 2006-01-25. 0000009302 00000 n Benzaldehyde dimethyl acetal used as an effective reagent for the construction of selenocarbonyl compounds. However, the chemicals are not in widespread use because they damage vegetation and contaminate water supplies.

Molecular Weight: 185.02 g/mol. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. endstream endobj 16 0 obj<> endobj 18 0 obj<> endobj 19 0 obj<>/Font<>/XObject<>/ProcSet[/PDF/Text/ImageC/ImageI]/ExtGState<>>> endobj 20 0 obj<> endobj 21 0 obj<> endobj 22 0 obj<> endobj 23 0 obj[/ICCBased 32 0 R] endobj 24 0 obj[/Indexed 23 0 R 255 33 0 R] endobj 25 0 obj<> endobj 26 0 obj<> endobj 27 0 obj<>stream 0000000945 00000 n The speed of this reaction depends on the substituents present in the aromatic ring. 0 The Technical grade is a versatile chemical intermediate in the manufacture of pharmaceuticals, dyes, perfume and flavoring chemicals. 0000002565 00000 n It is a member of benzaldehydes and a monomethoxybenzene. ChEBI. Benzyl alcohol can be formed from benzaldehyde by means of hydrogenation or by treating the compound with alcoholic potassium hydroxide thus undergoing a simultaneous oxidation and reduction which result in the production of potassium benzoate and benzyl alcohol. It has a role as a Brassica napus metabolite. Benzaldehyde can also undergo disproportionation in concentrated alkali (Cannizzaro's reaction): one molecule of the aldehyde is reduced to the corresponding alcohol and another molecule is simultaneously oxidized to the salt of a carboxylic acid. 0000002531 00000 n 2 Names and Identifiers Expand this section. 84T?�Hػ��H� ��-���0q]���r�P��u;v&������8u�(� �5���7 �$k0�]O���Jg;��3����&}��_ҧt�������ÜJv�K�a%|$�|����%[����|�HH�i@�2y�'J���W����sד�t��jQ=�+�(����A{à0�U@��ԅ��3F���Ҋ��~'��ԉ�=��qz冂 trailer 3-methoxybenzaldehyde is a member of the class of benzaldehydes in which the hydrogen at position 3 of benzaldehyde has been replaced by a methoxy group.
