Benzyl alcohol and benzoic acid group used as excipients
www.ema.europa.euReport published in support of the ‘Questions and answers on benzyl alcohol used as an excipient in medicinal products for human use’ (EMA/CHMP/50818 8/2013) and the ‘Questions and answers on benzoic acid and benzoates used as excipients in medicinal products for human use’ (EMA/CHMP/508189/2013)

One part of sodium benzoate is soluble in 1.8 parts of water at ordinary temperature, whereas only 0.34 parts of benzoic acid is soluble in 100 parts of water. Sodium benzoate is thus nearly 170 times as soluble as benzoic acid, pure sodium benzoate is tasteless and odourless.
Expt 5: Synthesis of Benzoic Acid Using the Grignard Reaction
tigerweb.towson.eduOne way to carry out this reaction is to bubble carbon dioxide gas into a solution of the Grignard reagent. However a more convenient alternative is to simply pour the Grignard reagent onto dry ice (solid CO 2). The immediate product of nucleophilic addition is actually a magnesium carboxylate, i.e. the magnesium salt of a carboxylic acid. In order

Experiment 3: Extraction: Separation of an Acidic, a Basic ...
www.bc.eduThe 4-chloroaniline is separated first by extraction with hydrochloric acid. Since no phenolic compound is present in this mixture, two extractions with base solution are not required; thus, the benzoic acid could be separated from the neutral compound by extraction with either aqueous sodium bicarbonate or aqueous sodium hydroxide solution.
Synthesis and Analysis of Acetyl Salicylic Acid
joshstaiger.orgIn the first part, FTIR spectra were collected for three different powders: aspirin, benzoic acid, and sodium salicylate. The MIDAC spectrometer was used. It was first necessary to prepare the sample that was placed in the apparatus. For each powder, approximately 10 mg was massed before it was ground to a fine powder using the mortar and pestle.

However, it is possible to stop the oxidation at the aldehyde stage with suitable reagents that convert the methyl group to an intermediate that is difficult to oxidise further. The following methods are used for this purpose. (a) Use of chromyl chloride (CrO2Cl2): Chromyl chloride oxidises
