Research of Technology of Cinnamic Acid Synthesized fron styrene and Carbon tetracholride by Two Step Reactions

The technology of cinnamic acid synthesized from styrene and carbon terrachloride by two step reactions has been researched in the paper. The paper suggested the appropriate conditions, i. e., reaction temperature, run-time and feed radio. The experiment results showed that styrene-carbon tetrachloride method is a better production method, which has some advantages of cheaper and easier feed, less environment pollution and higher-purity product compared with traditional Perkin method.
