Definitions
- the present invention relates to a method for producing an asymmetric phosphate-based compound, and more particularly, in synthesizing a desired asymmetric phosphate-based compound using a hyproxy-type compound as a starting material, it is easy to purify the reaction and has excellent reaction stability, It relates to a method for producing an asymmetric phosphate-based compound with a high yield of a target substance due to low side reactions.
- a phosphate-based compound that uses a cyclic compound (cyclic P-X, also referred to as hyproxy type) as a starting material can bind a cyclic compound different from the hyproxy type through dehydrohalogen.
- a cyclic compound different from the hyproxy type may form an asymmetric phosphate-based compound having a P-O-C structure as a skeleton.
- the resulting asymmetric phosphate-based compound is used as a versatile functional material such as an electrolyte solution for lithium ion batteries in industrial processes.
- an asymmetric phosphate-based compound is prepared through a hydrogen halide removal reaction using a hyproxy-type halogen compound as a starting material, and a base (C 3 H 9 N, C 6 H 15 as a hydrogen halide removal reagent generated during the reaction) N) is known.
- the base used as the hydrogen halide removal reagent since it forms a hydrochlorite-based solid material produced as a by-product after the reaction, it remains even after purification. Due to high reactivity, decomposition or ring opening occurs, resulting in a decrease in purity and yield.
- Patent Document 1 US Patent No. 9246187
- the present invention is easy to purify the reaction in synthesizing a desired asymmetric phosphate-based compound using a hyproxy-type compound as a starting material, has excellent reaction stability, and has few side reactions.
