Abstract: To research the cocatalyst effect of metal salt in cellulose hydrolysis by extremely-low acid,Choosing 7 different kinds of metal salts: K2SO4,MgSO4,Na2SO4,Al2(SO4)3,CuSO4,FeSO4,Fe2(SO4)3 in 3 different concentration as cocatalysts. Then,the results reveal that the cocatalyst effects of K2SO4、MgSO4、Na2SO4 are better. Repeating experements show that K2SO4 as cocatalyst is more stable. By the experimental results and literatures,we choose K2SO4 as representative metal salt inferring the mechanism of metal salt in cellulose hydrolysis by extremely-low acid,making a theoretical guidance for the subsequent research work.
