Synthesis method of N, N, N'-trimethyl-N'-hydroxyethyl diaminoethyl ether

The invention provides a synthesis method of N, N, N'-trimethyl-N'-hydroxyethyl diaminoethyl ether. The synthesis of the N, N, N'-trimethyl-N'-hydroxyethyl diaminoethyl ether comprises the following steps of firstly adding Tos- to dimethylaminoethoxyethanol, and then carrying out substitution reaction on the dimethylaminoethoxyethanol and N-methylethanolamine. The method has the advantages of few by-products, small safety risk, simple operation, high product yield and purity, and small amount of three wastes, and has excellent economic and environmental protection benefits.

Preparation method of N,N,N'-trimethyl-N'-hydroxyethyl diaminoethyl ether

The invention discloses a preparation method of N,N,N'-trimethyl-N'-hydroxyethyl diaminoethyl ether. The preparation method comprises the following steps: 1) in a solvent I, sequentially performing nucleophilic substitution and hydrolysis on N, N-dimethylethanolamine and chloroacetaldehyde dimethyl acetal which serve as raw materials to obtain 2-[2-(dimethylamino)ethyoxyl]acetaldehyde serving as an intermediate product; and 2) in a solvent II, mixing N-methylethanolamine and the 2-[2-(dimethylamino)ethyoxyl]acetaldehyde, performing hydrogenation amination on the mixture serving as a reaction system by taking Raney Ni as a catalyst to prepare the N,N,N'-trimethyl-N'-hydroxyethyl diaminoethyl ether. The N,N,N'-trimethyl-N'-hydroxyethyl diaminoethyl ether prepared by the method has the characteristics of simple process, low cost, high yield and low pollution.
