Among the three hydrolysis times tested (5, 10, and 20 min), the best compromise was reached, as stated by Marquie and Bourrely (1991), with the 10-min hydrolysis of the seed kernel meal with glacial acetic acid
at 100[degrees]C in a boiling-water bath.
To 1-mL aliquots we added 10, 20, 30, and 35 [micro]L of 50% glacial acetic acid
As we observed, these results prove the successful concentration to glacial acetic acid
using commercially available equipment," said Tom Schafer, Vice President of Koch Modular Process Systems, Inc.
