The synthesis of bis-dibenzoat, bis-p-dichloro-dibenzoat ethers of ethylene-glycol in the presence of ionic-liquid catalyst

Bis-dibenzoat and bis-p-dichloro-dibenzoat ethers of ethylene-glycol with 82–92 % of yield correspondingly were synthesized based on the benzoic, p-chlorobenzoic acids and ethylene-glycol in the ratio of 2:1,2, at 110 оС temperature and 6-7 hours of reaction duration in the presence of ionic liquid catalyst of n-methylpirralidon-hydrosulphate. The physical-chemical parameters of synthesized compound ethers have been specified and their structure identified spectrally. Synthesized compound ethers have been tested on the steadiness of diesel fuel against thermal oxidation.
