SYNTHESIS OF ASPIRIN (acetylsalicylic acid) Place 2.0 g (0.015 mole) of salicylic acid in a 125-mL Erlenmeyer flask. Add 5 mL (0.05 mole) of acetic anhydride, followed by 5 drops of conc. H 2 SO 4 (use a dropper, H 2 SO 4 is highly corrosive) and swirl the flask gently until the salicylic acid dissolves.; Heat the flask gently on the steam bath for at least 10 minutes.
Infrared spectroscopy (IR spectroscopy) has been described as being important in the techniques involved in drug design, development and the study of the reactions, which they are involved in. This allows an understanding of how drugs are metabolised within the body and thus provides a valuable insight into the pharmokinetics and pharmodynamics of the drug and thus its clinical use. IR.
Secoiridoids result from a branching in the mevalonic acid pathway in which terpene synthesis (oleoside moiety, see Figure 5.3) and phenylpropanoid metabolism (phenolic moiety) merge. These compounds are present in olive fruit and are released to VOO during the mechanical extraction process. Oleuropein is the most important representative of secoiridoid glycosides. It is present in high.
Due to a highly activating effect of the hydroxyl group in phenols, they undergo halogenation even in the absence of Lewis acids.When phenols are treated with bromine in the presence of a solvent of low polarity like CHCl 3 at low temperatures, monobromophenols are formed. When phenol is treated with bromine water, a white precipitate of 2, 4, 6-tribromophenol is formed.
Accurately weigh 3.00 grams of salicylic acid and transfer to a dry Erlenmeyer flask. If you will be calculating actual and theoretical yield, be sure to record how much salicylic acid you actually measured.; Add 6 mL of acetic anhydride and 5-8 drops of 85% phosphoric acid to the flask.
In this aspirin course work I will be investigating different types of aspirin and making aspirin. I will be looking at all the process taken to make aspirin and all the ingredients in aspirin.I Will be:Extracting some salicylic acid (2-hyroxy benzoic acid) from willow twigs or bark.OCOHOH2- hydroxy benzoic acid structureWe will also be learning about TLC (thin layer chromatograph), and its.
