Name: Eastman Propionic Acid
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Eastman Propionic Acid

High-purity grade with consistent batch-to-batch performance for reliable process control.
Low water content (<0.15%) minimizes side reactions in sensitive esterification and acylation processes.
Optimized acidity (pKa 4.87) provides effective pH control and buffering capacity in feed and food preservation systems.
Stable under ambient storage conditions with low volatility risk compared to shorter-chain carboxylic acids.
Produced via Eastman’s proprietary catalytic carbonylation process, ensuring trace metal impurities remain below detection limits.

Typical Applications Of Eastman Propionic Acid

Preservative in animal feed to inhibit mold, salmonella, and clostridia growth.
Chemical intermediate for synthesis of propionate esters used in fragrances, pharmaceuticals, and plasticizers.
pH adjuster and antimicrobial agent in bakery dough conditioners and dairy-based food systems.
Corrosion inhibitor component in oilfield fluid formulations and metalworking coolants.
Monomer modifier in specialty polyacrylate and polyvinyl acetate copolymer production.
