Technical Document

Brief Overview

Acrylic acid, characterized by its unsaturated carboxylic acid structure (CH2=CHCO2H), presents as a clear, odorless liquid. It exhibits distinct solubility in water owing to its polar carboxylic acid functional group and mixes well with moderately polar organic compounds like alcohols, ethers, and chloroform. However, its sensitivity to air and water makes it highly reactive with free radicals, electrophilic or nucleophilic agents. Under specific conditions such as exposure to heat, light, or certain chemicals, acrylic acid tends to undergo polymerization, sometimes explosively, even at room temperature. This compound also displays corrosive properties towards metals and tissues.In various applications, acrylic acid finds use in multiple forms, including free acids, ammonium, and alkali salts. It serves diverse purposes such as thickening agents, dispersants, flocculants, wetting agents, coatings, and textile finishes. Its reactivity with a wide array of organic and inorganic compounds makes it a valuable source material for producing various lower molecular weight compounds. For instance, through reactions with water, alcohols, amines, halogens, and chlorinated hydrocarbons, acrylic acid can generate derivatives of propionic a

cid. Additionally, it participates in reactions leading to unsaturated fatty acids, heterocyclic compounds, and Diels-Alder addition products.

Due to its tendency to explosively polymerize, acrylic acid requires stabilization using inhibitors like hydroquinone before shipping. Typically, there's no need to remove the stabilizer as its effect can be balanced by adding an excessive initiator.

Manufacturing Process

he primary method embraced for producing acrylic acid involves the vapor-phase oxidation of propylene, a byproduct obtained during the production of ethylene and gasoline, into acrolein. Chemical-Grade (CG) propylene is commonly combined with steam and air in a two-stage oxidation process. Initially, propylene undergoes oxidation to form acrolein, which subsequently undergoes further oxidation to yield acrylic acid. These oxidation steps are conducted within tubular, fixed-bed reactors, utilizing the heat released by the exothermic reactions to generate steam.

Water Treatment Industry

Acrylic acid monomers, when copolymerized, find application in wastewater treatment, particularly in the flocculation of mineral ore fines, wastewater treatment, and the remediation of sewage.
