0000001025 00000 n Reaction of benzaldehyde with anhydrous sodium acetate and acetic anhydride yields cinnamic acid, while alcoholic potassium cyanide can be used to catalyze the condensation of benzaldehyde to benzoin. 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. 0000001154 00000 n Q�=+��‚̓���6���2�\NUzi�Ra�����Hx��~�WzshN6�n��W�k���ٮ�d����������#\S���E�p���)���V鷯��,���'p&�O���?w����c��eT�w��]I�@�sQ�BP^���r�b�4��� ����l��,v�Ы�s(Ph'I�Ln��qJ��q��:�)FQTǕ�a�3GRԦZ�0zҭ�C�b&���MD��V�Ӏ{�S��XθO�6�\X������!L��C��J��b��1�W�q22��,Y������@��.rl��~�C@�Q�Q�B��m͂��tH�����C)v [�P�������E�xL���׏Z��TBR5�C�)�m5�.m㗤�I����׎����7�

0000005643 00000 n 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. Contents.

Glaciologists LaChapelle and Stillman reported in 1966 that benzaldeyde and N-heptaldehyde inhibit the recrystallization of snow and therefore the formation of depth hoar. Benzaldehyde (C 6 H 5 CHO) is a chemical compound consisting of a benzene ring with an aldehyde substituent.

It is the simplest representative of the aromatic aldehydes and one of the most industrially used members of this family of compounds. There are also a number of discontinued applications such as partial oxidation of benzyl alcohol, alkali treating of benzal chloride and reaction between benzene and carbon monoxide.

It is the primary component of bitter almond oil extract, and can be extracted from a number of other natural sources in which it occurs, such as apricot, cherry, and laurel leaves, peach seeds and, in a glycoside combined form (amygdalin), in certain nuts and kernels. 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.

On oxidation, benzaldehyde is converted into unpleasant smelling benzoic acid.
