Epichlorohydrin (ECH) is an intermediate chemical used in the production of epoxy resins (about 90% of the total global market), synthetic glycerin, epichlorohydrin elastomers, specialty water treatment chemicals, wetstrength resins for paper production, and surfactants.
Is epichlorohydrin hazardous?
Safety. Epichlorohydrin is classified by several international health research agencies and groups as a probable or likely carcinogen in humans. Prolonged oral consumption of high levels of epichlorohydrin could result in stomach problems and an increased risk of cancer.
How do you make epichlorohydrin?
Epichlorohydrin (1-chloro-2,3-epoxy propane), is obtained by the chlorination of propylene, followed by the reaction of allyl chloride with hypochlorous acid. The resultant product is treated with Ca(OH)2 and is a colourless liquid with a density of 1.18 g cm−3, mp −57 °C and bp 115 °C.
What is the chemical formula of epichlorohydrin?
C3H5ClO
Epichlorohydrin/Formula
What is the pH of epichlorohydrin?
Epichlorohydrin, which is colourless and poorly soluble in water and has a pungent, chloroform-like odour, is converted to 3-chloro-1,2-propanediol (α-chlorohydrin) in an aqueous milieu at a pH of 7 and 20°C.
Is epichlorohydrin volatile?
Epichlorohydrin is an epoxide compound that is volatile, highly reactive and unstable. Most commonly, epichlorohydrin is combined with Bisphenol A to form Epoxy resins. Epichlorohydrin has also been used as an Insecticide.
What PPE is needed when using epichlorohydrin?
NIOSH approved supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode.
How do you neutralize epichlorohydrin?
The epichlorohydrin containing epoxy compound can be treated with an alkali metal sulfite to reduce the amount of free epichlorohydrin either during or after processing. However, it is preferred that the treatment with sulfite be performed during processing.
What is the signal word for epichlorohydrin?
Danger

What is the molecular weight of epichlorohydrin?
92.52 g/mol
Epichlorohydrin/Molar mass
How do you handle epichlorohydrin?
Control measures include: (1) enclosing chemical processes for severely irritating and corrosive chemicals, (2) using local exhaust ventilation for chemicals that may be harmful with a single exposure, and (3) using general ventilation to control exposures to skin and eye irritants.
Is epichlorohydrin flammable?
Epichlorohydrin is a FLAMMABLE and REACTIVE LIQUID that can polymerize violently when exposed to HEAT. Use dry chemical, CO2, water spray or alcohol-resistant foam as extinguishing agents. Epichlorohydrin may form an ignitable vapor/air mixture in closed tanks or containers.
What is the main conversion of epichlorohydrin?
Epichlorohydrin is mainly converted to bisphenol A diglycidyl ether, a building block in the manufacture of epoxy resins. It is also a precursor to monomers for other resins and polymers. Another usage is the conversion to synthetic glycerol.
What is epichlorohydrin 106-89-8?
Epichlorohydrin (1-Chloro-2,3-Epoxypropane) 106-89-8 Hazard Summary Epichlorohydrin is mainly used in the production of epoxy resins. Acute (short-term) inhalation exposure to epichlorohydrin in the workplace has caused irritation to the eyes, respiratory tract, and skin of workers.
What is the hazard of epichlorohydrin?
Hazard Summary Epichlorohydrin is mainly used in the production of epoxy resins. Acute (short-term) inhalation exposureto epichlorohydrin in the workplace has caused irritation to the eyes, respiratory tract, and skin of workers. At high levels of exposure, nausea, vomiting, cough, labored breathing, inflammation of the lung,
Is epichlorohydrin soluble in water?
Epichlorohydrin. Despite its name, it is not a halohydrin. It is a colorless liquid with a pungent, garlic-like odor, moderately soluble in water, but miscible with most polar organic solvents. It is a chiral molecule generally existing as a racemic mixture of right-handed and left-handed enantiomers.
