Embodiment Construction

[0021] The implementation process of the present invention will be further elaborated below through specific examples.

[0022] 1. Synthesis of 5,5,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane

[0023] Synthesized according to the method of J.Chem..Soc.Perkin I, 591-593,1975.

[0024] 2. Synthesis of 1-acetyl-5,5,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane

[0025] Dissolve 28.5 grams (0.1 mol) of 5,5,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane in 500 milliliters of dichloromethane, add 20 grams (0.14 mol) anhydrous potassium carbonate, stirred and cooled to 0°C. A solution of 7.9 g of acetyl chloride dissolved in 100 ml of dichloromethane was added dropwise in one hour. After the addition, the temperature was gradually raised to room temperature, and stirring was continued for 3 hours, then heated to reflux for 3 hours, and the reaction was completed and cooled to room temperature. After filtration, the filtrate was concentrated by distil...

Abstract

The present invention is tetraazacyclo tetradecane derived ligand complexes and their synthesis process in fine chemical technology. Their macrocyclic ligand is 5, 5, 7, 12, 14, 14-hexamethyl-1, 4, 8, 11- tetraazacyclo tetradecane with 1-substituent; the metal ion in the complexes may be Fe, Cu or Mg ion. These complexes have the property of activating hydrogen peroxide and per-acids.

Description

Technical field: [0001] The invention belongs to the field of fine chemical industry, and relates to a class of macrocyclic ligand complexes and a synthesis method. Background technique: [0002] Peroxide bleaching has important applications in both industrial and household bleaching and washing processes. This application often requires a catalyst to activate peroxides. For example, in the paper industry, some catalysts are very effective in activating hydrogen peroxide, thereby It can greatly improve the efficiency of pulp hydrogen peroxide bleaching. [0003] Some transition metal complexes are mainly used as catalysts for activating peroxides, such as the iron, manganese, and copper complexes disclosed in the invention patent No. 99813089.3 filed by the Netherlands Unilever Co., Ltd. in China. In recent years, the application of catalyst-activated peroxide systems has been significantly expanded. For example, the research group led by Professor TerryCollins of Carnegie ...
