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.

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

The invention discloses a synthesis method of N, N, N'-trimethyl-N'-hydroxyethyl diaminoethyl ether. The synthesis method comprises the following steps of: in a solvent I, adopting dimethylaminoethoxyethanol as a raw material, and under a catalytic system of 2, 2, 6, 6-tetramethyl piperidinoxide-FeCl3-tertbutyl nitrite, utilizing oxygen gas to oxidize the dimethylaminoethoxyethanol into 2-[2-(dimethylamino)ethoxy]acetaldehyde; in a solvent II, mixing N-methylethanolamine with the 2-[2-(dimethylamino) ethoxy]acetaldehyde, adopting Raney Ni as a catalyst, adopting the above mixture as a reactionsystem to carry out hydrogenation and amination, and preparing the N, N, N'-trimethyl-N'-hydroxyethyl diaminoethyl ether. The N, N, N'-trimethyl-N'-hydroxyethyl diaminoethyl ether synthesized by adopting the synthesis method has the characteristics of simple process, low cost, high yield and less pollution.

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.

Preparation method for series of polyurethane catalysts

The invention discloses a preparation method for a series of polyurethane catalysts. The preparation method comprises the following steps: SioO2 and Al2O3 with different ratios are employed as carriers, soaked in an ammonium sulfate aqueous solution, dried and roasted, and a silicon-aluminum-loaded solid acid catalyst is prepared; then a mixture of N,N-dimethyl ethanolamine and N-methyl diethanolamine is employed as a raw material, the raw materials and the silicon-aluminum-loaded solid acid catalyst accounting for 1-10% of the total weight of the raw material are added in an autoclave and a reaction is carried out; the filtrate after the reaction is subjected to rectification separation and therefore N-methyl morpholine, 2-dimethylaminoethyl ether and N,N,N'-trimethyl-N'-hydroxyethyl-bis-amino ethyl ether are obtained respectively.
