Obtención de lignina y celulosa de residuos de maíz

Abstract

Mediante un método de pulpeo sencillo se obtuvo la lignina y la celulosa de tusa y olote de maíz con buenos rendimientos. Los estudios de termogravimetría mostraron que estas ligninas son térmicamente menos estables que la Lignina Kraft de maderas suaves. Por medio de varios métodos se determinó que las celulosas de desechos de maíz son menos cristalinas que la celulosa de Avicel de la casa Merck.

Using a simple pulping method, lignin and cellulose were obtained from corn waste in good yield. Thermal analysis results showed that lignins were thermally less stable than Kraft Lignin from soft woods. Using several different methods, it wasfound that the celluloses were less cristallin than Avicel cellulose.
