Updated: 2026-08-05

Overview

2-Propenylacrylic acid is an unsaturated carboxylic acid with a molecular formula of C6H8O2. It is primarily used in industrial applications, particularly in polymer chemistry and specialty coatings. The compound features reactive double bonds, making it valuable for cross-linking and polymerization reactions. Due to its chemical structure, 2-propenylacrylic acid is often employed as a monomer or intermediate in the synthesis of resins, adhesives, and other high-performance materials. Its moderate volatility and solubility in common organic solvents enhance its versatility in formulation processes.

Physical and Chemical Properties

2-Propenylacrylic acid is a colorless to pale yellow liquid with a density of approximately 1.02 g/cm³. It has a boiling point in the range of 200-210°C and is soluble in organic solvents like ethanol and acetone, though its solubility in water is limited. The compound's key chemical properties include its reactive double bonds, which participate in addition and polymerization reactions. These properties make it useful for creating cross-linked polymers and coatings. Stability under normal storage conditions is good, but exposure to strong oxidizers or high temperatures should be avoided.

Main Applications

The primary use of 2-propenylacrylic acid is in the production of polymers and specialty coatings. Its reactive nature allows it to serve as a building block for resins, adhesives, and sealants, providing durability and chemical resistance. In the coatings industry, it is valued for its ability to enhance film-forming properties and adhesion. Additionally, it finds niche applications in the synthesis of specialty chemicals, where its double bonds enable tailored modifications for specific performance requirements.

Safety and Storage

2-Propenylacrylic acid is classified as an irritant, posing risks to skin and eyes upon contact. Proper personal protective equipment (PPE), including gloves and goggles, is essential when handling this chemical. Adequate ventilation is also recommended to minimize inhalation exposure. Storage should be in a cool, dry place, away from direct sunlight and oxidizing agents. Containers must be tightly sealed to prevent moisture absorption and degradation. Spills should be contained and cleaned promptly using appropriate absorbent materials.

B2B Procurement Guide

When procuring 2-propenylacrylic acid, buyers should prioritize supplier reliability and product consistency. Key factors to evaluate include purity levels (typically 95% or higher), batch-to-batch uniformity, and compliance with industry standards. Requesting certificates of analysis (CoA) and material safety data sheets (MSDS) is advisable. Pricing varies depending on quantity and supplier, so obtaining multiple quotes is recommended. For large-scale purchases, consider negotiating long-term contracts to secure stable pricing and supply.
