How is epichlorohydrin produced?
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 another name for epichlorohydrin?
It is a colorless liquid with a pungent, garlic-like odor, moderately soluble in water, but miscible with most polar organic solvents….Epichlorohydrin.

Is epichlorohydrin carcinogenic?
EPA has classified epichlorohydrin as a Group B2, probable human carcinogen.
Where is epichlorohydrin used?
epoxy resins
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.
What is epoxy resin made of?
Epoxy resins are produced industrially from raw materials that are for the most part derived from petroleum. An epoxy resin is a polyepoxide comprised of reactive prepolymers and polymers that contain epoxide groups. Epoxide groups are commonly known as epoxy which is known as a strong adhesive.
What is epichlorohydrin used for?
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.
What is the signal word for epichlorohydrin?
Signal word Danger Page 2 Page 2 of 8 Hazard statement(s) H226 Flammable liquid and vapour. H301 + H311 + H331 Toxic if swallowed, in contact with skin or if inhaled H314 Causes severe skin burns and eye damage. H317 May cause an allergic skin reaction. H350 May cause cancer.
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.
Where does resin come from?
Resins are produced in special resin cells in plants, and are also produced when an injury occurs to the plant. Resins can be produced through the bark of a tree, the flowers of an herb, or the buds of a shrub.
Who invented epoxy?
Seventy-five years ago, in a small lab in Louisville, Kentucky, Dr. Sylvan O. Greenlee invented a material that may have seemed ordinary to most, but he knew that he had just discovered a material that would enable the future. That landmark discovery was liquid epoxy resin.
Where does epoxy resin come from?
The vast majority of epoxy resins are themselves an industrial product which are derived from petroleum and are also the result of an epoxide reactive process. All depending on the type of reaction that was used to produce them, cured epoxy resins can either be like honey, or something much more viscous.
What is the primary use of epichlorohydrin?
The principal uses for epichlorohydrin are in the production of epoxy resins (its primary use), synthetic glycerin, epichlorohydrin elastomers, specialty water treatment chemicals, wet-strength resins for paper production, and surfactants.
What is the history of epichlorohydrin production in China?
Chinese epichlorohydrin production started in the 1960s. As demand for epichlorohydrin picked up during 1997–2007, China had to rely heavily on imports because of its lack of capacity. In the mid-2000s, demand rose quickly, imports increased substantially, and domestic companies increased epichlorohydrin capacity.
Which country consumes the most epichlorohydrin in the world?
China has been the world’s largest epichlorohydrin-consuming country since the late 2000s; in China, epichlorohydrin is used primarily for the production of epoxy resins, accounting for approximately 97\% of total epichlorohydrin consumption.
What is happening to the epichlorohydrin and epoxy resins industries?
Over the past decade, the epichlorohydrin and epoxy resins industries have suffered from low profitability, mainly because of an excessive buildup of capacity in China. China now accounts for about 50\% of global nameplate capacity, although it is believed that a number of plants are running at reduced operating rates.
