The present invention uses a nitrogen-containing organic compound to be reacted with an alkyl sultone to obtain a zwitterion compound. The zwitterion compound is reacted with a heteropoly acid (HPA) to obtain an ionic liquid HPA (IL-HPA). The IL-HPA is used for acetylation of polyol and HOAc for obtaining polyol acetate. The IL used in the reaction can be recycled. Thus, problems of product separation, waste acid handling, and corrosion of facilities are solved and production through esterification is improved with a green catalysis.

Method of synthesizing polyol acetate by using catalyst of ionic liquid heteropoly acid

The present invention fabricates diethylene-glycol tert-butyl ether (DEGtBE) by using isobutylene and diethylene glycol (DEG) coordinated with an acidic cation exchanged resin as catalyst. Through two stages of vacuum distillations, highly selective and pure DEGtBE is produced. Moreover, a byproduct of diethylene-glycol di-tert-butyl ether (DEGDtBE) can be recycled.

A method for synthesizing exo-tetrahydrodicyclopentadiene (exo-THDCPD) and adamantane is provided, including isomerization of an endo-tetrahydrodicyclopentadiene (endo-THDCPD) as a reaction feed with an acidic ionic liquid of aluminum trichloride in a pseudo-fixed bed ionic liquid reactor. Reactants float as a droplet from bottom to top of the pseudo-fixed bed reactor, and finally are discharged from a side tube. A mole fraction of aluminum trichloride in the acidic ionic liquid of aluminum trichloride is from 0.5 to 0.9, a feeding rate of the reaction feed is 0.1-10 g/min, and a temperature for the isomerization is between 25-120&#xb0; C.

An exo-tetrahydrodicyclopentadiene is produced from endo-tetrahydrodicyclopentadiene through isomerization reaction. An acidic ionic liquid is used in the isomerization. The isomerization of endo-tetrahydrodicyclopentadiene gives a reaction conversion and a selectivity both higher than 99%. Besides, the ionic liquid used is environmental-friendly and recyclable.
