Potassium hydrogen persulfate composite powder with uniform and stable quality and preparation process thereof

Abstract

The invention relates to the field of pharmaceutical chemicals, in particular to potassium hydrogen persulfate compound powder with uniform and stable quality and a preparation process thereof. The potassium hydrogen persulfate compound powder comprises the following components: a potassium hydrogen persulfate compound, sulfamic acid, sodium hexametaphosphate, sodium dodecyl sulfate, sodium chloride, an anti-caking agent and trisodium citrate, and also comprises essences and pigments. The potassium hydrogen persulfate compound powder disclosed by the invention is superior to potassium hydrogenpersulfate compound powder on the market, the process is simple, and the cost is hardly increased; the compound powder is uniform in appearance, color and content; a user can conveniently monitor theeffective disinfection concentration in real time in clinical use, products are not layered in the transportation process, and the product quality is more stable. According to the process, closed integrated equipment can be adopted for production in actual production, so that pollution to people and the environment is greatly reduced, and the process is the direction of safe and environment-friendly production in the future.

Description

technical field [0001] The invention relates to the field of medicine and chemical industry, in particular to a potassium hydrogen persulfate composite powder with uniform and stable quality and a preparation process thereof. Background technique [0002] Potassium persulfate complex powder is a broad-spectrum, efficient, reliable, durable and safe environment-friendly disinfectant composed of potassium persulfate and sodium chloride. It has an efficient killing effect on pathogenic microorganisms such as bacteria, viruses, fungi, and mycoplasma. The epidemic control departments of the United States, the United Kingdom and other countries have approved the use of potassium hydrogen persulfate compound powder for the prevention and control of major epidemics, and it is also the first and only veterinary disinfectant approved and registered by the US environmental protection department for the prevention of foot-and-mouth disease. . The Animal Husbandry and Veterinary Bureau...

Problems solved by technology

Because there are many components in the potassium hydrogen persulfate compound powder, each of which has different properties, and its particle size, fluidity and particle size are quite different, the products on the market mainly have the following three types of problems: (1) due to the fine particle size of amaranth, Poor fluidity makes the uniformity of its color poor; (2) Due to the difference in particle size and brittleness of materials, especially sodium dodecylbenzenesulfonate is a surfactant, which is not easy to crush and easy to form agglomerates. Affect the appearance uniformity and internal quality of the product; (3) The above two types of problems further affect the internal quality of the product, making the pH value of the product unstable, and the chloride and content uniformity are also poor, which directly affects the stability and disinfection of the product Effect

[0005] However, there are not many relevant documents on how to improve the stability, appearance uniformity and pH influence of potassium hydrogen persulfate composite powder disinfectant on its stability at present.

The only few documents and the patent "A Potassium Hydrogen Persulfate Compound Powder for Preventing Agglomeration and Its Preparation Method and Application" (Application No. CN201711470217.9) mentioned the above-mentioned related problems, and the focus was mainly on prescription adjustment. However, the characteristics of materials such as amaranth and sodium dodecylbenzenesulfonate in the prescription cannot fundamentally solve the problem
