3. H. 8. Vanillyl alcohol is derived from vanillin. Reaction Sodium Borohydride Vanillin to Vanillyl Alcohol 2.00 g of vanillin used 0.5g of NaBH4 used Filter Paper: 0.19g Watch Glass: 43.17 g Add a stir bar, clamp the flask above a stir plate and commence stirring at room temperature to solublize the vanillin. O. Using the syringe provided in the hood, add 2 mL of 1 M NaOH to the vanillin in the conical vial. OH H H MW 37.83 Vanillyl Alcohol MW 154.06 C. 8. After the vanillin goes into solution, add an ice bath under your flask to cool the solution. 2. O + OH OCH. H. 10.

Pre-lab Questions for reduction of vanillin 1. Vanillyl alcohol is often used as an intermediate in the production of perfumes and flavorings. 3. Vanillyl alcohol is a monomethoxybenzene that is 2-methoxyphenol substituted by a hydroxymethyl group at position 4. In determining the theoretical yield of vanillyl alcohol, you should have used vanillin as the limiting reagent, even though we use fewer millimoles of …

If the mixture does not dissolve after 5 minutes of continuous stirring add another 5 mL NaBH4 and cool the solution to just below 15°C. 3. It is used to flavor food. It has a role as a plant metabolite.

H O OCH. 3. OH 1. Vanillin is a naturally-occurring version of natural vanilla extract and is widelysynthesized and utilized as a substitute due to its low production cost compared to naturalvanilla. Place 380 mg (0.380 g) of vanillin in a clean 5 mL conical reaction vial containing a spin vane. Sodium Borohydride will be used to reduce vanillin to vanillyl alcohol. It is a …

4, NaOH 2. 1. 1. O. In a separate reaction vial, dissolve 0.5 g H. 3. 2. NaBH. Vanillin MW 152.15 C. 8. The purpose of this experiment is to see if vanillin can be synthesized to vanillyl alcohol through reduction with sodium borohydride. It is the main component of both natural and artificially produced vanilla extracts 1.Vanillin can be reduced through sodium borohydride (NaBH 4 ), as well as lithium aluminumhydride (LiAlH 4 ), to produce vanillyl alcohol—a molecule that is widely used in the flavoring ofdifferent foods.
