Ephedra Oil Separation And Synthesis Of Ibuprofen Ester Amide Pseudoephedrine

This experiment use Gas chromatography-mass spectrometry Analysis of the naphtha Chemical composition, Contains32and27compounds respectively in Horsetail ephedra, active ingredients in naphtha is L-a-terpinene alcohol, this experiment use TLC come to separate L-a-terpinene alcohol use solubility grouping and NMR and qualitative analysis was carried out on separation of products. Determination of the molecular formula and acid value, iodine value, saponification value, ibuprofen pseudo hemp have antipyretic analgesic and alleviate nasal mucosal hyperemia, this drugs is common in daily life. In the process of synthesis produce ibuprofen pseudoephedrine ester. Study with chemical synthesis method synthesis separation of impurities PE, to provide the suppor to chemical synthesis ibuprofen pseudo hemp.This article is divided into three parts:1) main features of active ingredients of ephedra oil and extraction method.2) this is experiment par t, introduced the extraction technology of ephedra collected in brown oily matter analysis methods, steps and results analysis.3) synthesis of ibuprofen ester amide pseudoephedrine, ibuprofen and pseudoephedrine Separation, the chromatography column method to separate two substances, this experiment use TLC come to separate use solubility grouping and NMR and qualitative analysis was carried out on the separation of products, the molecular structure and molecular of two substances is determined。...
