Embodiment 1

[0021] Embodiment 1: the preparation method of 2,2'-diamino-4,4'-bithiazole nickel chelate (DABT / Ni)

[0022] In a 500ml round bottom flask, accurately weigh 1.98g of 2,2'-diamino-4,4'-bithiazole (DABT), add 300ml of ethanol, stir to dissolve, add nickel sulfate (NiSO 4 ·6H 2 O) 5.26g, under the protection of nitrogen, stirred and refluxed for 72 hours, precipitated with acetone, and filtered to obtain a light blue powdery solid, soaked and washed with acetone and methanol until the filtrate was free of SO 4 2- (with BaCl 2 reagent test), vacuum drying, the product is 2,2'-diamino-4,4'-bithiazole nickel chelate (DABT / Ni), and the weight is 4.57g.

Embodiment 2

[0023] Embodiment 2: the preparation method of 2,2'-diamino-4,4'-bithiazole copper chelate (DABT / Cu)

[0024] In a 500ml round bottom flask, accurately weigh 1.98g of 2,2'-diamino-4,4'-bithiazole (DABT), add 300ml of ethanol, stir to dissolve, add copper sulfate (CuSO 4 ·5H 2 (0) 5.00g, under the protection of nitrogen, stirred and refluxed for 72 hours, precipitated with acetone, and suction filtered to obtain a blue-gray powdery solid, soaked and washed with acetone and methanol until the filtrate was free of SO 4 2- (with BaCl 2 reagent test), vacuum drying, the product is 2,2'-diamino-4,4'-bithiazole copper chelate (DABT / Cu), and the weight is 4.89g.

Embodiment 3

[0025] Embodiment 3: the preparation method of 2,2'-diamino-4,4'-bithiazole ferrous chelate (DABT / Fe)

[0026] In a 500ml round bottom flask, accurately weigh 1.98g of 2,2'-diamino-4,4'-bithiazole (DABT), add 300ml of ethanol, stir to dissolve, add ferrous sulfate (FeSO 4 ·7H 2 (0) 5.56g, under nitrogen protection, stirred and refluxed for 72 hours, precipitated with acetone, and filtered to obtain a light brown-green powdery solid, soaked and washed with acetone and methanol until the filtrate was free of Fe 2+ (with NH 4 SCN and H 2 o 2 Reagent test), vacuum drying, the product is 2,2'-diamino-4,4'-bithiazole ferrous chelate (DABT / Fe), and the weight is 4.93g.

Abstract

The invention relates the preparing method of 2, 2'- diamino- 4, 4'- thiazole transient metal chelate and supermolecule magnetic material. The method comprises the following steps: preparing chelate complex with 2, 2'- diamino- 4, 4'- thiazole and transient metal, then mixing the chelate complex and polyacrylic acid, and getting supermolecule magnetic material. The invention has the advantages of novel style method, stable magnetic property, high saturation intensity, and little hysteresis loss.

Description

technical field [0001] The invention relates to a 2,2'-diamino-4,4'-bithiazole transition metal chelate, a supramolecular magnetic material and a preparation method thereof. Background technique [0002] With the development of society and the advancement of science and technology, inorganic magnetic materials are far from meeting people's requirements. Since the emergence of organic and polymer magnetism in the world in the mid-1980s, polymer and organic magnetic materials have attracted more and more scholars at home and abroad because of their excellent performance and characteristics. Although all countries have invested a lot of manpower and material resources to carry out research, but there are very few of them that have real application value. Contents of the invention [0003] The purpose of the present invention is to provide 2,2'-diamino-4,4'-bithiazole transition metal chelates and their supramolecular magnetic materials and preparation methods, to develop and...
