Product Application of Acrylic acidCAS#79-10-7
Chemical Reactivity & Derivative Monomer Introduction
Acrylic acid carries typical carboxylic acid functional group and active carbon-carbon double bond, presenting diversified chemical reactivity. It can conduct esterification reactions with various alcohol substances to generate corresponding acrylic ester products.
All acrylic acid esters and their metal salt derivatives are uniformly named acrylates, also known as propenoates under systematic chemical nomenclature.
The mainstream alkyl acrylate monomers synthesized from acrylic acid raw material include methyl acrylate, ethyl acrylate, butyl acrylate and 2-ethylhexyl acrylate. These acrylate monomers are core intermediate raw materials widely used in water-based coatings, industrial adhesives, textile binders, superabsorbent polymers and printing ink manufacturing.

FAQ
Q: What key risks and storage limits should we notice during acrylic acid storage and transportation?
A: Acrylic acid has two major hazards: strong corrosive irritation and auto-polymerization risk.
- Temperature control: Keep storage and transit temperature within 15–25°C; temperatures above 30°C will accelerate polymerization, while temperature below 13.5°C will cause crystallization and uneven distribution of stabilizer.
- Segregation rule: Strictly separate acrylic acid from strong oxidants and strong alkaline chemicals to avoid violent chemical reactions.
- Container requirement: All sealed packaging must retain proper MEHQ inhibitor content and partial dissolved oxygen to inhibit runaway polymerization during long-term storage.
