Benzaldehyde Specification

Benzaldehyde(CAS NO.100-52-7)is slightly soluble in water but is miscible in all proportions with alcohol or ether. On standing in air, benzaldehyde oxidizes readily to benzoic acid. Benzaldehyde (CAS NO.100-52-7) 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.

Physical properties about Benzaldehyde are: (1)ACD/LogP: 1.452; (2)ACD/LogD (pH 5.5): 1.45; (3)ACD/LogD (pH 7.4): 1.45; (4)ACD/BCF (pH 5.5): 7.48 ; (5)ACD/BCF (pH 7.4): 7.48; (6)ACD/KOC (pH 5.5): 146.93; (7)ACD/KOC (pH 7.4): 146.93; (8)#H bond acceptors: 1; (9)#Freely Rotating Bonds: 1; (10)Index of Refraction: 1.567; (11)Molar Refractivity: 33.006 cm³; (12)Molar Volume: 101.099 cm³; (13)Polarizability: 13.084 10-24cm³; (14)Surface Tension: 38.8059997558594 dyne/cm; (15)Density: 1.05 g/cm³; (16)Flash Point: 62.778 °C; (17)Enthalpy of Vaporization: 41.504 kJ/mol; (18)Boiling Point: 178.749 °C at 760 mmHg; (19)Vapour Pressure: 0.973999977111816 mmHg at 25°C

Preparation of Benzaldehyde: Commercially, Benzaldehyde may be produced

(1) By heating benzal chloride (C₆H₅CHCl₂) with calcium hydroxide:
C₆H₅CHCl₂ + Ca(OH)₂ → C₆H₅CHO + CaO + 2HCl
(2) By heating calcium benzoate and calcium formate:
(C₆H₅COO)₂Ca + (HCOO)₂Ca → 2C₆H₅CHO + 2CaCO₃(3) By boiling glucoside amygdalin of bitter almonds with a dilute acid.

Benzaldehyde is manufactured in two grades, technical and refined. The technical grade is largely used as an intermediate in the synthesis of other chemicals, such as benzyl benzoate, cinnamic aldehyde, and dyes.

Most of the technical grade is made by direct vapor-phase oxidation of toluene, although some is made by chlorinating toluene to benzal chloride, followed by alkaline or acid hydrolysis. For perfume and flavoring use, the refined, chlorine-free grade is required, which is economically produced by the direct vapor-phase oxidation of toluene with air at 500 ℃.
C₆H₅CH₃ + [O] → C₆H₅CH=O

It is claimed that a catalyst mixture of 93% uranium oxide and 7% molybdenum oxide gives relatively high yields. The oxidation is sometimes carried out in the liquid phase by using manganese dioxide/sulfuric acid at 40 ℃.

Uses of Benzaldehyde: Benzaldehyde is used as a flavoring material, in the production of cinnamic acid, in the manufacture of malachite green dye, as an ingredient in pharmaceuticals, and as an intermediate in chemical syntheses.While benzaldehyde is commonly used as a commercial food flavorant (almond flavor) or industrial solvent, it is used chiefly in the synthesis of other organic compounds, ranging from pharmaceuticals to plastic additives. Benzaldehyde is also an important intermediate for the processing of perfume and flavoring compounds and in the preparation of certain aniline dyes.
