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, chemical disinfectants must be used to ensure that the space is sterile. At the same time, the chemical disinfectants must have high sterilization efficiency and guaranteed use under low temperature conditions After leaving no residue, peracetic acid solution is generally used as the main disinfectant for aseptic cold filling lines (CAF). However, the existing peracetic acid disinfectant has low concentration, poor stability, short shelf life, and the concentration of hydrogen peroxide increases after recycling, causing secondary pollution and other problems. Specifically,...
