Abstract

Ionic liquids with Dimethyl Phosphate Anion as Highly Efficient Materials for Technological Processes: A Review

Highlights

  • Ionic liquids (ILs) have gained a stable position in technology and research in the last quarter of the 20th century

  • Catalytic hydrogenation has been investigated in ILs-dimethyl phosphate (DMP) over atomically dispersed supported metal catalysts, and the results have demonstrated a wide range of options for adjusting the catalytic properties of the catalysts used [94]

  • Just the first attempts are made in using these materials in oil chemistry

Summary

Introduction

Ionic liquids (ILs) have gained a stable position in technology and research in the last quarter of the 20th century. According to the second method, ILs-DMP are prepared by alkylation with the trimethyl phosphate of a pre-made salt, which has the chloride anion in its structure, such as ammonium, phosphonium, or nitrogen heterocyclic onium chlorides [11] [12]. The mixture of the salt and trimethyl phosphate is stirred and heated at 100– 120 °C for that purpose, the end of the gas (chloromethane) evaluation signaling for the end of the reaction This anion metathesis reaction greatly increases the diversity of the substances to be obtained and removes the main constraint of the first method, the compulsory introduction of a methyl group in the cations of ILs-DMP, expanding the range of available ILs-DMP. The choice of the analyses mainly depends on the utilization needs of ILs-DMP
