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

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.
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.

www.bc.edudeprotonated. Hydrochloric acid is generally used to protonate amines. The solid forms of the acidic and basic organic compounds can be recovered from the aqueous solution using the same solubility switch principles. When acid is added to an aqueous solution that contains the salt of a deprotonated organic acid, the organic acid is re-protonated.
