摘要：

An oxypropylation reaction was carried out by suspending sugar beet pulp in propylene oxide in the presence of a basic catalyst and heating the resulting mixture under pressure. Optimisation of the conditions (pulp granulometry, type and amount of catalyst, relative proportion of pulp with respect to propylene oxide, amount of residual moisture and temperature) allowed quantitative conversion of the pulp into polyols possessing different viscosities and OH numbers.
