Application
Epichlorohydrin is a versatile chemical intermediate primarily used in the production of epoxy resins. It reacts with bisphenol A to form diglycidyl ethers, which are the backbone of high performance coatings, adhesives, composites, and electrical laminates. In the synthesis of synthetic glycerin, epichlorohydrin is hydrolyzed to monochlorohydrin and then to glycerol, serving as a major route for glycerin production. The compound is also a precursor for elastomers such as epichlorohydrin rubber (ECO and GECO), which offer excellent oil, fuel, and ozone resistance for automotive and industrial hoses and seals. In water treatment, epichlorohydrin is used to produce cationic flocculants by reacting with dimethylamine and ammonia, resulting in polyamine polymers that clarify raw water and treat industrial wastewater. The pharmaceutical industry employs it as an alkylating agent for synthesizing beta blockers (e.g., propranolol, atenolol) and other drugs. Additionally, epichlorohydrin is used in paper wet strength resins (polyamide epichlorohydrin resins), textile finishing agents, and ion exchange membrane manufacturing.

FAQ
Q1 How should epichlorohydrin be stored safely?
A Store in a cool, dry, well ventilated area away from ignition sources, strong acids, bases, and metal halides. Keep container tightly sealed. Shelf life is 12 months under recommended conditions due to slow epoxide ring opening.
Q2 What purity grades do you supply?
A Standard grade is 99.5 percent minimum. We also offer 99.9 percent grade for high performance resins and pharmaceutical intermediate applications.
Q3 Is epichlorohydrin soluble in water?
A Slightly soluble in water (about 6 g per 100 mL at 20 deg C) and miscible with most organic solvents such as acetone, toluene, and dichloromethane.
Q4 Do you provide sample quantities for formulation development?
A Yes, free samples of 1 kg are available for qualified US companies. Shipping fee applies for small quantities due to hazardous material classification.
Q5 What are the common impurities in epichlorohydrin and how do you control them?
A Key impurities include 1,3 dichloro 2 propanol and 2,3 dichloro 1 propanol. Our process limits each below 0.10 percent by GC. Full impurity profiles are provided with each certificate.
Q6 Can you supply epichlorohydrin with stabilized inhibitors?
A Yes, we can add inhibitors such as nitroalkanes or tertiary amines to suppress polymerization during long term storage. Please specify your requirements.
