Catalytic hydrolysis of cellulose into reducing sugar (RS) over solid acid catalysts is one of efficient pathways for the conversion of biomass into fuels and chemicals. In this study, we developed a new method for the hydrolysis of cellulose into RS in ionic liquids
The hydrolysis of aluminum-tri-(sec-butoxide), ASB, in ionic and nonionic media is shown to be a useful method for the synthesis of aluminum minerals. Infrared and X-ray analysis were used to identify the reaction products. Pseudoboehmite is formed at low water to
Hydrolysis of cellulose in ionic liquid 1-butyl-3-methyl imidazolium chloride was greatly affected by the content of water. The highest RS yield and glucose selectivity were obtained in and at 110 C after 3 h with the weight ratio of
Depolymerization of cellulose and hemicellulose from loblolly pine wood is studied in the ionic liquid 1-butyl-3-methylimidazolium chloride, which is capable of dissolving carbohydrates and lignin. In the presence of an acid catalyst, the carbohydrate fraction is converted into water-soluble products under milder conditions than reported for similar reactions in the aqueous phase. The water
With ionic liquids as solvents and corn straw as raw material, different processes of lignocellulose pretreatment with acid as catalyst were studied under conventional irradiation and the reducing sugar was measured. The results indicated that acid can accelerate hydrolysis reaction of corn straw into reducing sugar with ionic liquids as solvent, and microwave irradiation
Salt hydrolysis is defined as the process in which a salt reacts with water to give back the acid and the base. Salt +water Acid + Base BA + H2O HA + BOH All salts are strong electrolytes and thus ionize compley in the aqueous solution. (1)
Hydrolysis of Aluminum-Tri-(Sec-Butoxide) in Ionic and Nonionic
Hydrolysis of Equations A salt is an ionic compound that is formed when an acid and a base neutralize each other. While it may seem that salt solutions would always be neutral, they can frequently be either acidic or basic. Consider the salt formed when the

Abundant plant biomass has the potential to become a sustainable source of fuels and chemicals. Realizing this potential requires the economical conversion of recalcitrant lignocellulose into useful intermediates, such as sugars. We report a high-yielding chemical process for the hydrolysis of biomass into monosaccharides. Adding water gradually to a chloride ionic liquid-containing

Controversy behind the postulation that ionic liquids (ILs) are entirely green materials emerged a few years ago. This statement is not always valid, and properties such as toxicity and stability of ILs should be fully characterized to evaluate their potential use as green solvents. Therefore, in this work, the thermal and chemical decompositions of
