Abstract
Systematic studies in the field of the synthesis of ethers based on glycerol and polycyclic unsaturated hydrocarbons have been carried out. The reactions of glycerol addition to cyclohexene, bicyclo[2.2.1]hept-2-ene, tricyclo[5.2.1.02,6]deca-3,8-diene, tetracyclo [4.4.12,5.17,10.01,6]dodec-3-ene and their alkyl-substituted derivatives were carried out in the presence of a homogeneous catalyst - boron trifluoride etherate (BF3 · OEt2). It was revealed that the BF3 · OEt2 catalyst promotes the successful transformation of the above-indicated polycyclic olefins and their alkyl-substituted derivatives into glycerol monoethers in the yields of 70-87, 81 and 64-74 %, respectively. The effects of temperature, reaction duration, the molar ratio of initial components and the amount of the catalyst on ether yields were studied, and the optimal conditions for the synthesis of bi-, tri- and tetracyclic glycerides were determined. The synthesized ethers may be used as additives to synthetic oils.
