Kinetic Study of the Esterification Between Citric Acid Molecules and Dombeya Mollis’ Leaf Cellulose Titrated by Spectrophotometer UV-Visible Procedure

Cellulose is the most abundant natural organic polymer on earth and could be valorized and used in different applications. It’s mainly used to produce paper but also to produce biodegradable cellophane and biofuels. Thus, the extraction of cellulose from green plants, where it’s the most important structural component, was interesting. This manuscript treated the extraction of cellulose from the Dombeya Mollis leaf by esterification-reaction with citric acid molecules. This method is usually used to extract, to identify, to characterize and to quantify the active molecules of alive organisms but in this case the advantage to use the esterification-reaction with citric acid molecules is that the synthesized solution contains straightaway reticulated cellulose. Indeed, the refractive index value of the Dombeya Molli leaf’s cellulose-citric acid esterified solution was 1.336 in the vicinity of the refractive index values of citric acid-solid, citric acid in solution and nanocellulose which were respectively 1.493, 1.345 and 1.470. In addition, A cellulose quantification procedure using spectrophotometer UV-visible was performed and established in this manuscript and permitted to quantify the quantities of cellulose extracted from the plants to the solution by esterification-reaction with citric acid molecules. In consequence, a kinetic study was done under this esterification-reaction between citric acid molecules and Dombeya Mollis leaf’s cellulose and permitted to evaluate the speed constant with the partial orders of citric acid, cellulose and proton-H+ which play the role of catalyst-inductive during this esterification-reaction. At the end, a reactional mechanism which could govern this esterification-reaction between the Dombeya Mollis leaf’s cellulose and the citric acid molecules was proposed.
