Abstract:    

It has been established the possibility for phenol allylation 

on natural zeolites and them analogs. Here is demonstrated the synthesis of 

allyl phenol, which has wide industrial applications. The offered method in 

comparison with the traditional methods has more advantages – higher 

selectivity, smaller material and power resources consumption. It has been 

obtained the mixture of allylating phenols (30%) in general with allyl 

phenyl ether (1) with 80% yields. At 600 K is obtained allylphenyl ether, at 

700 K beginning the formation of allyl phenols, which is the result of direct 

C-allylation of the aromatic ring. It has been investigated the possibility of 

Claisen rearrangement in the same conditions. All of that are established by 

gas-liquid chromatography and liquid chromatography data.

INTRODUCTION 

 

In the processes of chemical technology, as a rule, there are a lot of stages and 

manufactures, which can be supplemented by various stages of recycling processes. 

Allyl phenols are raw material for the manufacture of a wide assortment of organic 

compounds, in producing of biologically active compounds, accelerators for rubber 

vulcanization, explosives, lubricant oils, gasoline anticorrosive additives, etc.  

Finding of new ways for synthesis and chemical transformation of allyl phenol, despite 

of rich history of researches, still presents scientific and applied interest.
