Abstract: Hazardous chemicals applied in industry suffer great risks and would result in potential danger. As a new type of ionic liquids, deep eutectic solvents (DES) are known for safety, environments friendly, and inexpensive. DES have attracted more and more attentions, and been considered as a promising substitute of hazardous chemicals. This statement was mainly devoted to introduce the definition of principles of green chemistry and GSK solvent selection guide, and apply them to the safety assessment of chemical industry with Deep Eutectic Solvents replacing of hazardous chemicals. In the passage, the harm from hazardous chemicals in chemical industry was firstly reviewed. Based on this, the advantage of DES was illustrated, and it was a promising replacement of hazardous chemicals. The definition, classification, and the properties of DES were descripted. The application progress of DES in preparing metal-catalysts, biomass transformation, gas separation, polymerization, and electrochemical to substitute for hazardous chemicals were reviewed. The behaviors of DESs in replacement of hazardous chemicals were studied according to the Principles of green chemistry and GSK solvent selection guide. As solvent, DES can replace inflammable and highly toxic organic solvents, such as toluene and benzene, which were dangerous to environment. As catalyst, DES can enhance the selectivity and efficiency. As reactant, DES can avoid the usage of toxic reactant. Moreover, the problems and difficulties in research and applications were investigated, and then the prospective application of DES was offered.
