Abstract

Acyl mannoses with acyl chain lengths of 8-16 were continuously produced at 50 degreesC using a plug-flow-type reactor packed with an immobilized lipase, Chirazyme(R) L-2. 2-Methyl-2-propanol dehydrated over 5A molecular sieves was used as the reaction medium. Irrespective of the acyl chain, a conversion of more than 0.5 was achieved at the superficial residence time ro equal to or longer than 20 min. It was demonstrated that 6-o-myristoyl mannose could be produced at a conversion of ca. 0.4 for at least 16 days using the reactor operated at tau (o) = 12 min, and that 6-o-lauroyl and 6-o-caproyl mannoses could also be produced at similar conversions with the same residence time. The surfactant properties of the produced capryloyl, caproyl,lauroyl and myristoyl mannoses were also determined at 25 degreesC. (C) 2001 Elsevier Science B.V. All rights reserved.
