Hemicellulose in corn straw: Extracted from alkali solution and produced 5-hydroxymethyl furfural in HCOOH/HCOONa buffer solution

This diagram demonstrated the whole experimental process which roughly divided into two steps. In the first step, hemicellulose of corn straw was extracted in alkaline solution and specific precipitant. During this process, several factors had been investigated for the maximum of hemicellulose. The next step was the degradation procedure. Buffer solution and hemicellulose were mixed into the iron batch autoclave under high temperature for a period of time. The products of the mixture were detected by HPLC, NMR, FTIR and other testing means. The buffer solution could be used for recycling for 4 times.178
