Research on the Disproportionate Synthesization of p-Cymene from Monocyclic Monoterperpene

This paper focuses on the technique requirements for disproportion synthesizing p-cymene with monocyclic monoterperpene as raw material and CD molecular sieve as catalyst.Through spectrual analysis of the end products of the experiment, the advantageous characteristics of CD molecular sieve are identified as follow s:easy for preparing, low cost, easy for recycling, pollution- and erosion-free. In addition, the monocyclic monoterperpene is commonly found in industrial side-products and the overall cost can be sharply reduced.
