FIELD: chemistry.
SUBSTANCE: process of alkylating phenols with alkenyl-hem-dichlorocyclopropanes is carried out in the presence of a boron trifluoride etherate catalyst at temperature 50-65°C. The process with phenol is carried out with the following ratio of components in wt %: boron trifluoride etharate 18-19; alkenyl-hem-dichlorocyclopropanes 18-21. The process with 2,6-di-tert-butylphenol is carried out with the following ratio of components in wt %: boron trifluoride etherate 10-11; alkenyl-hem-dichlorocyclopropanes 10-13.
EFFECT: high output as well as quality of the end product.
