Design Basis
Propionic Acid: Synthesized from
Syngas (1:1 ratio of CO & H2) Ethylene Oxygen
Low level of toxicity as mentioned by EPA Major Uses:
Preservative for animal & human food consumption Intermediate product for Thermoplastics Bactericide, fungicide and pesticides

Chemical Information Analysis Reaction Mechanism
Syngas feed with Ethylene PropionaldehydeCatalyst: Rhodium(1) CO + H2 +C2H4 CH3CH2CHO
Aldehyde oxidation Propionic AcidCatalyst: Cobalt Ion(2) CH3CH2CHO + ½ O2 CH3CH2COOH
In = Out (per year) 6.64E7 lb (CO+H2+C2H4+O2)= 6.64E7 lb Product

Catalyst Information Rhodium: Used in the production of
Propionate Extremely durable to poisonous material Reaction conditions: 212°F, 290 psi
Cobalt Halide: Used in the oxidation of Propionate to Propionic acid Dissolve cobalt halide in water to obtain ion Poison: K2CO3
Reaction Conditions: 122°F, 14.7 psi
