High yield of isosorbide production from sorbitol dehydration catalysed by amberlyst 36

Isosorbide (ISB), one of the important polyols, can be produced through the sequential intramolecular dehydration of sorbitol derived from abundance renewable biomass resource. The advantages of its rigid structure has granted the ISB a wide application in the polymer industries. Acidic catalyst in...
