Embodiment 1

[0026] A high-concentration and high-stability monobasic peroxyacetic acid disinfectant, consisting of the following raw materials in weight percentage: glacial acetic acid 71%, hydroxyethylidene diphosphonic acid 3%, hydrogen peroxide 17%, sodium gluconate 3%, Water 6%.

[0027] Preparation method: Add glacial acetic acid and hydroxyethylidene diphosphonic acid to the reaction kettle according to the above ratio, stir at room temperature and pressure for 5 minutes, and then slowly add sodium gluconate at a temperature not higher than 30℃, and stir until The solution is clear and transparent, then stand for 10 minutes, add hydrogen peroxide, stir for 10 minutes under normal temperature and pressure, and prepare the final solution. Finally, the final solution is matured at 27°C for 10 days under airtight conditions to obtain the monobasic peracetic acid disinfectant.

Embodiment 2

[0029] A high-concentration and high-stability monobasic peroxyacetic acid disinfectant, composed of the following raw materials in weight percentage: glacial acetic acid 72%, hydroxyethylidene diphosphonic acid 3%, hydrogen peroxide 18%, and sodium gluconate 2%. Water 5%.

[0030] Preparation method: Add glacial acetic acid and hydroxyethylidene diphosphonic acid to the reactor according to the above ratio, stir at room temperature and pressure for 10 minutes, then slowly add sodium gluconate under the condition of not higher than 30℃, and stir until The solution is clear and transparent, then let it stand for 8 minutes, then add hydrogen peroxide, stir at room temperature and pressure for 10 minutes to prepare the final solution, and finally mature the final solution at 28°C for 8 days under airtight conditions to obtain the monobasic peracetic acid disinfectant.

Embodiment 3

Abstract

The invention discloses a high concentration high stability one-element peracetic acid disinfectant and a preparation method thereof, and the high concentration high stability one-element peracetic acid disinfectant consists of the following raw materials by weight: 71%-73% of acetic acid, 1%-3% of hydroxyethylidene diphosphonic acid, 17%-20% of hydrogen peroxide, 1%-3% of sodium glucoheptonate, and balance of water. The preparation method is as follows: adding the acetic acid and the hydroxy ethylidene diphosphonic acid into a reaction kettle, stirring for 5-15min at normal temperature and under normal pressure, slowly adding the sodium glucoheptonate at the temperature no higher than 30 DEG C, stirring until the solution is clear and transparent, standing for 7-10min, adding the hydrogen peroxide, stirring for 10min at normal temperature and under normal pressure to prepare a final solution, curing for 7-10 days at 27-30 DEG C under airtight condition to obtain the one-element peracetic acid disinfectant. The one-element peracetic acid disinfectant is prepared by using hydroxyethylidene diphosphonic acid and sodium glucoheptonate composite stabilizer, by adjusting the formula, peracetic acid concentration is high, stability is good, shelf life is long, recycling cycle is long, hydrogen peroxide content is low, and the problem of secondary emission pollution caused by recycling use can be avoided.

Description

Technical field [0001] The invention relates to the technical field of disinfectants, in particular to a high-concentration and high-stability monobasic peracetic acid disinfectant for aseptic cold filling lines of beverages and a preparation method thereof. Background technique [0002] In the current beverage production, in order to ensure the continuous high-speed aseptic filling of the production line, a chemical disinfectant must be used to ensure the sterility of the space. At the same time, the chemical disinfectant must have high sterilization efficiency and ensure its use under low temperature conditions. There is no residue afterwards, and peracetic acid solution is generally used as the main disinfectant for aseptic cold filling lines (CAF). However, the existing peracetic acid disinfectants have problems such as low concentration, poor stability, short shelf life, and increased hydrogen peroxide concentration after recycling, causing secondary pollution. The specific ...
