WebThe dehydration of succinic acid to succinic anhydride has been brought into the spotlight due to its environmental-friendly process. However, it is still an industrial challenge to enhance the dehydration performance under moderate reaction conditions. In this study, a series of acid-treated niobic acid catalysts were prepared for the dehydration of succinic … Web(57) [Summary] The present invention relates to a method for producing anhydrous or almost anhydrous formic acid. In this case, first, aqueous formic acid is produced by hydrolysis of methyl formate, and at that time, methanol contained therein is previously removed from methyl formate. The process according to the invention comprises, before …

WebOutline: # Nomenclature Classification Physical properties Classification Physical properties WebChemical procedures such as acid hydrolysis, chlorination, alkaline extraction are used for the purification of cellulose (Astley & Donald, 2001; Mora´n, Alvarez, Cyras, & Va´zquez, 2008). In amorphous regions, the rate of acid hydrolysis is more. As a result, the cellulose which is left after a major portion of cellulose is pure.
