This article
describes a simple and rapid gas chromatographic method for identification of
residual solvents present in benzyl alcohol. Benzyl alcohol is used in foods
and pharmaceutical products.
The organic
solvents such as benzene, chlorobenzene and toluene are frequently used
in manufacturing of benzyl alcohol. Even after such
manufacturing process, some solvents still remain in small quantities.
Method for the
quantification of residual solvents present in benzyl alcohol was done by gas
chromatography with flame ionization detector and utilizes the Agilent 7700
with FID (DB-624, 30 m × 0.53 mm, 3 μ) capillary column, nitrogen as carrier
gas with a flow rate of 2.5 ml mn-1.
