| titleOfInvention | Ethrel by product 2 chloroethyl phosphoric acid acid anhydride changes into the method for 2 chloroethyl phosphoric acid |
| abstract | The by product 2 chloroethyl phosphoric acid acid anhydride that the invention discloses the production of a kind of ethrel changes into the method for 2 chloroethyl phosphoric acid, the present invention by ethrel by product 2 chloroethyl phosphoric acid acid anhydride at the temperature of 75 ~ 100 DEG C by common hydrolysis and at the temperature of 85 ~ 110 DEG C the method for lower boiling acid catalysis back hydrolysis, be converted into 2 chloroethyl phosphoric acid completely, thus make the mass content of the former medicine of ethrel be promoted to 91% ~ 96% from 82% ~ 90%, the significantly lifting of the former medicine of ethrel, has widened the export market of ethrel product further; The invention provides a kind of efficient, low cost, have the new technology by product 2 chloroethyl phosphoric acid acid anhydride that ethrel is produced being changed into 2 chloroethyl phosphoric acid of industrial value. |
