PROCESS FOR PREPARING DIALKYL CARBONATES |
摘要 |
<p>Process for preparing dialkyl carbonates A b s t r a c t Dialkyl carbonates can be prepared by reaction of carbon monoxide with alkyl nitrites in a continuous gas-phase reaction using a platinum metal catalyst on a metal phosphate support and adding hydrogen halide stepwise or continuously during the course of the reaction in almost quantitative selectivity; the corresponding dialkyl oxalates are formed in such small amounts that in most cases they cannot be detected.</p> |
