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 g cm −3, mp −57 °C and bp °C. It is a Epichlorohydrin book liquid with a pungent garlic.
Epichlorohydrin is a volatile and flammable, clear, colorless, liquid, chlorinated cyclic ether with an irritating, chloroform-like odor that emits toxic fumes of hydrochloric acid and other chlorinated compounds when heated to decomposition.
Epichlorohydrin is used in the manufacture of epoxy resins, synthetic glycerin and elastomers. Exposure to epichlorohydrin irritates the eyes, skin. Other names: Oxirane, 2-(chloromethyl)- (2S)-; (S)-Epichlorohydrin; (2S)-chloromethyl-oxirane Permanent link for this species.

Description Epichlorohydrin PDF
At low temperatures, ECH shows excellent aging characteristics, high resiliency, and flexibility. Does your application involve high temperatures exceeding ° F. If so, ECH sponge rubber performs well as a gasket or seal in applications. Webster's bibliographic and event-based timelines are comprehensive in scope, covering virtually all topics, geographic locations and people.
They do so from a linguistic point of view, and in the case of this book, the focus is on "Epichlorohydrin," including when used in literature (e.g.
all authors that might have Epichlorohydrin in their name).Author: Icon Group International. epichlorohydrin Jerzy Gacaa*,Graz˙yna Wejnerowskaa and Piotr Cysewskia The present studies show that the currently accepted scheme for the hydrolysis of epichlorohydrin (ECH) needs to be extended by an additional path which makes allowance for the formation and decomposition of.
Epichlorohydrin definition is - a volatile liquid toxic epoxide C3H5ClO having a chloroform odor and used especially in making epoxy resins and rubbers. If epichlorohydrin is spilled on land, it most likely will volatilize or leach into the subsurface; biodegradation and hy-drolysis also may occur in soil.
Bioaccumulation in aquatic organ-isms is unlikely (HSDB ). Occupational exposure may occur during the production of epichlorohydrin and during its use to synthesize end products.

Epichlorohydrin (a.k.a. ECH, Chloromethyloxirane) is an epoxide and an organochlorine compound. It is not a halohydrin, as its name could suggest. In its pure form, epichlorohydrin is a clear, colorless liquid. The versatility conferred by the presence of both an epoxide ring and a chlorine atom explains epichlorohydrin's wide use as a chemical.
Analysis of Epichlorohydrin Dissolved from Metal Food Cans by GC This test method provides for GC/FID measurement of epichlorohydrin, one of the raw material monomers of epoxy resin used as an internal-surface coating in metal food cans.

epichlorohydrin (% purity), 6 hours/day, 5 days/week (duration-adjusted to17, and 34 mg/cu.m, respectively), for exposures. Epichlorohydrin vapor was generated by metering the liquid into a warmed vaporization flask then passed through the chamber airflow with compressed Size: KB.
Epichlorohydrin was administered in aqueous solution at, and mg/kg. A dose of rag/kg did not produce any observable signs of toxicity during 2 weeks of observation.
The two highest doses produced mortality in both rats and mice usually within the first 48 hours after treatment. The signs of toxicity observed were lethargy. Epichlorohydrin is an unstable liquid with an odor like that of chloroform. In animals, epichlorohydrin is irritating and systemically toxic by all routes of exposure (Shell Chemical Corporationas cited in ACGIH /Ex.p.
Polyamideamine epichlorohydrin (PAE) resin is a water soluble and the most used permanent wet strength additive in alkaline conditions for preparing wet strengthened papers. In this thesis, we studied some properties of PAE resins and wet strengthened papers prepared from them.In a toxicology book, a chapter stated that humans exposed to epichlorohydrin vapor at 20 ppm for 1 h experienced burning of the eyes and nasal mucosa, that exposure at 40 ppm caused ocular and throat irritation that lasted about 48 h, and that ppm was intolerable to man, with potential for pulmonary edema and renal lesions (Lefaux ).Epichlorohydrin ALS Environmental may or may not test for Epichlorohydrin (CAS # ).
