Why is vanillin soluble in water?
Vanillin has a soothing, pleasant aroma. Its molecular weight is relatively low, and it is fairly volatile. The oxygen-containing groups attached to the ring in vanillin can form strong hydrogen bonds with water, making it water soluble (about a gram of vanillin can be dissolved in 100 mL of cold water).
How do you dissolve vanillin?
Vanillin is soluble in water,ethyl alcohol, pyridine ,glycerol,oils and aqueous alkali hydroxides. For scent traps we can use ethyl alcohol or a mixture of alcohol water,according to requirements.

Is vanillin soluble in ethyl acetate?
Vanillin is sparingly soluble in water but freely soluble in ethyl acetate and short- chain alcohols. Ethyl acetate chosen for aqueous extraction on account of immiscibility with water and ease ofdrying.
Is vanillin soluble?
Solubility: Vanillin is soluble in cold water, diethtl ether, acetone and is very soluble in hot benzene, and petroleum ether. Vanillin is freely soluble in chloroform, carbon disulfide, glacial acetic acid, pyridine, oils, and in aqueous solutions of akali hydroxides.
Is vanilla extract soluble in water?
One of the main flavour molecules within vanilla is vanillin (see vanilla vs vanillin). Vanillin is one of the main molecules you’d want to extract when making a vanilla extract. The solubility of vanillin is 50mg/ml whereas it is only 10mg/ml in water (source).
Why does vanillin dissolve in NaOH?
The reason for dissolving our Vanillin in NaOH is because we wanted to deprotonate the the “OH” on the Phenol so that when we add the NaBH4, the hydride can attack the carbonyl group and not the hydrogen on the “OH “and from H2 gas. Sodium borohydride reduces the aldehyde group in vanillin to primary alcohol.
What is the chemical name of vanilla?
Vanillin
Vanillin is an organic compound with the molecular formula C8H8O3. It is a phenolic aldehyde. Its functional groups include aldehyde, hydroxyl, and ether. It is the primary component of the extract of the vanilla bean.
Is vanillin polar or nonpolar?
Due to the commulative effect of the functional groups of the compound, vanillin is a polar molecule. Vanillin is an organic compound with the molecular formula of C8H8O3.It is a phenolic aldehyde.
Is vanillin highly soluble in water?
Slightly soluble in cold water, soluble in hot water, soluble in ethanol, ethyl ether, propylene Ketone, benzene, chloroform, carbon disulfide, glacial acetic acid, pyridine and volatile oil.
What is the solubility of vanillin in cold water?
Solubility: Vanillin is soluble in cold water, diethtl ether, acetone and is very soluble in hot benzene, and petroleum ether. Vanillin is freely soluble in chloroform, carbon disulfide, glacial acetic acid, pyridine, oils, and in aqueous solutions of akali hydroxides. Solubility in water.
Which is the most common name for vanillin?

How is vanillin used as a natural antimicrobial?
The utilization of vanillin was studied as a natural antimicrobial in a combined technology for producing a shelf-stable strawberry puree. Mild heat treatment (blanching) was combined with addition of 3,000 ppm vanillin and 500 ppm ascorbic acid and adjustment of water activity (aw) to 0.95 and pH to 3.0.
