synthesized by reaction of
1,2-epoxydodecane with potato starch in aqueous alkaline medium. Careful
attention has been given to the purification steps and more precisely
to the identification and quantification of the impurities. The purification
by Soxhlet extraction compared to the process by grinding required
fewer steps but a longer time. The values of the MS were always around
1.1, but the recovery yields were higher for the treatment by grinding
compared to Soxhlet (85 vs 63%).
