producing large quantities of propylene from steam crackers and coal-based MTO/
MTP process and has increased production of acrylic acid for SAP production.
BASF-YPC (a 50:50 joint venture of BASF and Sinopec) has constructed a new
super-absorbent polymer (SAP) plant with a capacity of 60,000 mtpa [138].
4.3.4 Processes for the Production of Acrylic Acid:
Commercial Perspective
The oxidation of acrolein is the earliest synthesis of acrylic acid and it was occurred
in 1843. Since 1927, several commercial processes have come up for producing
acrylic acid that include ethylene cyanohydrins process, the Reppe process, the
β-propiolactone process, and the acrylonitrile hydrolysis. In recent time, the research
effort has been put to develop microbe for producing 3-hydroxypropionic acid by
fermentation. 3-Hydroxypropionic acid then underwent dehydration reaction to
form acrylic acid.
Acrylic Acid Production from Propylene by Catalyzed Oxidation
Currently, the majority of acrylic acid is produced through two-step selective partial
oxidation of propylene in presence of suitable catalytic system [139]. Two reactions
happen in tubular fixed-bed reactor system connecting in series. Following two
reactions occur in two reactors (Scheme 13).
