| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | chloroforme-2-chloroethyl Ester is an intermediate of the fungicide oxaoling. organic synthesis. used as intermediate for medicine and pesticide |
| production method | the preparation method is to add chloroethanol in a phosgene reactor, start stirring, phosgene is then passed through a phosgene flow meter. The phosgene temperature is 40~50 ℃, and the phosgene is continued for 20~24H. When the endpoint is close to the end point, the phosgene is stopped after reaching the standard, and then the phosgene and hydrogen chloride are driven away by nitrogen, phosgene was destroyed and decomposed, and the gas was driven to pH = 5~6, and the sample was analyzed as a product.
