ISOTHERMAL PROCESS FOR PHOSPHOROMONOCHLORIDITE SYNTHESIS |
摘要 |
<p>The present invention relates to a process for preparation of a phosphoro- monochloridite in high yield by contacting phosphorus trichloride (PCI3) with an aromatic diol in a solution of one or more organic solvents under reaction conditions sufficient to produce the phosphoromonochloridite. The reaction is carried out by adding a feed solution containing the aromatic diol dissolved in a first organic solvent into a reaction zone containing PCI3, and optionally one or more second organic solvents, the addition being conducted so as to maintain substantially isothermal process conditions. The reaction solution comprises less than 5 mole percent of a nitrogen base. (Formulae I,II)</p> |
