Verfahren zum Herstellen von di-tert-butyl Dicarbonat |
摘要 |
<p>An industrially advantageous process for producing di-tert-butyl bicarbonate from tert-butyl alcohol and an alkali metal comprises continuously carrying out the following steps: (A) reacting tert-butyl alcohol with sodium to form sodium tert-butoxide; (B) reacting the sodium tert-butoxide with carbon dioxide to form mono-tert-butyl sodium carbonate; and (C) reacting the mono-tert-butyl sodium carbonate with an aromatic sulfonyl halide such as p-toluenesulfonyl chloride in the presence of a tertiary amine such as N,N,N',N'-tetramethylethylenediamine, without isolating an intermediate in the middle of each reaction stage.</p> |
