Embodiment 1

[0020] (1). Put 15kg of 8% ryosinic acid, 39kg of salicylic acid and 150kg of water into a 500kg reactor equipped with heating device, electric stirring, thermometer and dropping funnel, and mix and stir until it is completely dissolved. Add 30kg of solid copper acetate and 30kg of solid aluminum acetate to the mixed solution, stir and react for 0.5 hours to obtain a mixed solution;

[0021] (2) Add 226 kg of a 10% aqueous solution of sodium hydroxide to the mixed solution, and the addition is completed within 2 hours. After the addition is complete, the reaction is stirred for 3.5 hours to complete the complexation reaction;

[0022] (3). Filter the complexed reactant, wash with water until neutral, and dry, and the solid obtained is the finished copper-lead complex salt.

Embodiment 2

[0024] (1). Put 15kg of ryosinic acid, 40kg of salicylic acid and 150kg of water with a concentration of 10% into a 500kg reactor equipped with heating device, electric stirring, thermometer and dropping funnel, and mix and stir until completely dissolved. Add 37kg of solid copper acetate and 37kg of solid aluminum acetate to the mixed solution, stir and react for 1 hour to obtain a mixed solution;

[0025] (2) Add 226 kg of a 13% aqueous solution of sodium hydroxide to the mixed solution and complete the addition within 2 hours. After the addition is complete, stir and react for 4 hours to complete the complexation reaction;

[0026] (3). Filter the complexed reactant, wash with water until neutral, and dry, and the solid obtained is the finished copper-lead complex salt.

Embodiment 3

[0028] (1). Put 15kg of ryosinic acid with a concentration of 13%, 45kg of salicylic acid and 150kg of water into a 500kg reactor equipped with heating device, electric stirring, thermometer and dropping funnel, and mix and stir until completely dissolved. Add 45kg of solid copper acetate and 45kg of solid aluminum acetate to the mixed solution, stir and react for 1.5 hours to obtain a mixed solution;

[0029] (2) Add 226 kg of 15% aqueous sodium hydroxide solution to the mixed solution, and the addition is completed within 2 hours. After the addition is complete, the reaction is stirred for 4.5 hours to complete the complexation reaction;

[0030] (3). Filter the complexed reactant, wash with water until neutral, and dry, and the solid obtained is the finished copper-lead complex salt.

Abstract

The invention relates to a method for preparing a copper-lead complex salt, which comprises the following steps of: (1) putting resorcinol acid, salicylic acid and water into a reaction kettle, mixing and stirring the mixture until complete dissolution, adding solid copper acetate and solid aluminum acetate into the mixed solution, and stirring the mixture to perform reaction for 0.5 to 1.5 hours so as to obtain the mixed solution; (2) dropping aqueous solution of sodium hydrate, and stirring the mixture to perform reaction for 3.5 to 4.5 hours after dropping to finish a complex reaction; and (3) filtering a reactant after the complex reaction, washing the reactant until the reactant is neutral, and drying the reactant to obtain a solid namely the finished product of the copper-lead complex salt. By determining the optimal reaction condition, the reaction yield is improved and the method is more suitable for requirements on industrial production so as to meet the market requirements and obtain successful exports. Besides, the method improves the market competitiveness of an enterprise and ensures that the product can be widely promoted and applied in the market.

Description

Technical field [0001] The invention belongs to the field of organic compound preparation, in particular to a method for preparing a copper-lead complex salt. Background technique [0002] Solid propellant is the power source material of solid rocket motor and plays an important role in the development of missile and aerospace technology. It can usually be divided into double-base propellant, composite propellant and modified double-base propellant. Copper-lead complex salt is a kind of catalyst for double-base propellant. It is widely used in the catalysis of double-base propellant. It combines the advantages of two base materials. At present, the synthesis method of copper-lead complex salt has been reported in some domestic and foreign documents. These existing synthesis methods are roughly the same and have a wide range of applications, but the yield of products synthesized by this method is low, not suitable for industrial production, and cannot meet market requirements.
