sorbitol anhydride monoacetylated acid solution

Organic Synthesis Engineering

Organic Synthesis Engineering The symmetric diols are selectively monoacetylated probably due to the higher rate of monoacetylation compared to the rate of diester formation from the monoester The partial hydrogenation step was carried out using Pd on carbon in a solution of MPD in aqueous acetic acid and a conversion of with a
