Computed Properties of C8H12O4. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: cis-Cyclohexane-1,2-dicarboxylic acid, is researched, Molecular C8H12O4, CAS is 610-09-3, about FT-IR and FT-Raman spectroscopy study of the cyclic anhydride intermediates for the esterification of cellulose. Part 3. Cyclic anhydrides formed by the isomers of cyclohexanedicarboxylic acid. Author is Yang, Charles Q.; Zhang, Guobao.
Multifunctional carboxylic acids were used as crosslinking agents for cotton and wood pulp cellulose. In the authors’ previous research, the authors found that a polycarboxylic acid esterifies cellulose through the formation of a 5-membered cyclic anhydride intermediate by the dehydration of 2 carboxyl groups. The authors studied the formation of those cyclic anhydride intermediates by different isomers of cyclohexanedicarboxylic acid (CHA) so that the authors can elucidate the effects of mol. structure on the formation of the anhydride intermediates. The authors found that both cis- and trans-1,2-CHA form 5-membered anhydride intermediates when temperature reaches their m.p. and that cis-1,2-CHA forms the cyclic anhydride at temperatures lower than does trans-1,2-CHA. 1,3-CHA forms 6-membered cyclic anhydride at temperatures much higher than its m.p. The formation of a 5-membered cyclic anhydride intermediates takes place at temperatures lower than that of a 6-membered anhydride. This is probably the main reason why those polycarboxylic acids with their carboxylic acid groups bonded to the adjacent carbons of the mol. backbones are more effective crosslinking agents for cellulose than those with their carboxylic groups bonded to the alternative carbons. No formation of cyclic anhydride was found for 1,4-CHA. The formation of a 5-membered cyclic anhydride was accelerated by monosodium phosphate, which is used as a catalyst for the esterification of cotton cellulose by polycarboxylic acids.
After consulting a lot of data, we found that this compound(610-09-3)Computed Properties of C8H12O4 can be used in many types of reactions. And in most cases, this compound has more advantages.
