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 {HEAD ~ the sodium tert butoxide} with {TAIL ~ 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
