Condensation:Â Firstly,
a chemical reaction is carried out to synthesize the condensation
product of para-aminobenzoic acid (PABA) and glutamic acid. This
condensation product undergoes a series of reactions and processing
steps to ultimately form the structural framework of folic
acid.
Acid purification:Â The
synthesized folic acid solution is subjected to acid purification
to remove impurities and contaminants. Acid purification is
typically performed using dilute acids such as sulfuric acid or
hydrochloric acid to treat the solution. By adjusting the acidity,
alkalinity, and temperature, impurities are induced to precipitate.
Solid impurities are then separated by methods like filtration or
centrifugation, resulting in a relatively pure folic acid
solution.
Alkali
purification:Â The folic acid solution is reacted with a
strong alkali, such as sodium hydroxide, to aid in the removal of
residual impurities and contaminants. Subsequently, the pH of the
solution is adjusted through neutralization, gradually approaching
neutrality.
Acid
precipitation:Â Folic acid in the acidic solution undergoes
a reaction with acid, leading to its conversion into a solid
precipitate. The precipitate is then separated by methods such as
filtration or centrifugation.
Spray drying or flash
drying:Â The folic acid precipitate is sprayed into hot air
to facilitate rapid evaporation and formation of fine particles.
Another commonly used method is flash drying, where the folic acid
precipitate is exposed to a high-temperature environment to quickly
evaporate moisture and form dried
particles.
Packing:Â The dried
folic acid powder is packaged using sealed containers or bags to
ensure long-term storage and freshness of the
product.
Finished Product:Â The
final step involves labeling and quality inspection of the packaged
folic acid product. The product is evaluated according to quality
standards to ensure compliance with specified quality requirements
and purity standards.
