Discussion on Technology Scheme of Preparing High Value Chemicals From Tobacco Rod
Tobacco rod is one of the important raw materials for direct extraction and preparation of nicotine.High purity nicotine can be prepared from tobacco rod by alkaline hydrolysis-extraction.In view of the large amount of solid waste residue after the synthesis of nicotine from tobacco rod,the residue was further hydrolyzed into high value chemical levulinic acid,and the optimization of the production process was discussed.The results showed that the optimized process route could improve the technical economy of the project,and solve the problem of solid residue treatment in the process of nicotine production.This schema had construction significance for the reconstruction and expansion of new and existing nicotine projects,and is also a feasible scheme for improving the comprehensive benefits of nicotine projects.
