| titleOfInvention | Process for producing di-tert-butyl dicarbonate |
| abstract | A process for producing di-tert-butyl dicarbonate by continuously carrying out the following steps of reacting tert-butyl alcohol with sodium to form sodium tert-butoxide, reacting the sodium tert-butoxide with carbon dioxide to form mono-tert-butyl sodium carbonate, and 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. This process is an industrially advantageous process for producing di-tert-butyl dicarbonate from tert-butyl alcohol and an alkali metal. |
