Embodiment 1

[0242] (1) Add 18kg of ethanol, 0.5kg of disodium edetate, 0.1kg of fatty alcohol polyoxyethylene ether and 64kg of water into the reactor, stir and dissolve at 30-40°C for 45 minutes to form a stable and uniform solvent system;

[0243] (2) Add 0.55 kg of phthalaldehyde to the solvent system obtained in step (1), and stir the solution for 60 minutes at a temperature of 30 to 40° C. to form a stable and uniform phthalaldehyde solution;

[0244] (3) dissolve the sodium bicarbonate of 0.3kg with the water of 16.55kg, filter the solution that obtains, the solution that filters is added to the o-phthalaldehyde solution that step (2) obtains, stirs 115 minutes, the pH value of solution is 8.8, Stand still for 30 minutes, filter to obtain the disinfectant of the present invention, pH is 9.

[0245] The disinfectant that present embodiment makes has following composition:

[0246] 0.55% o-phthalaldehyde, 18% ethanol, 0.1% fatty alcohol polyoxyethylene ether, 0.5% disodium edetate, ...

Embodiment 2

[0248] Preparation method is identical with embodiment 1, and difference is composition content:

[0249] 1.0% o-phthalaldehyde, 40.0% propanol, 0.01% disodium edetate, 5.0% fatty alcohol polyoxyethylene ether, 0.1% sodium hydroxide, 63.89% water, pH 9.5.

Abstract

A disinfectant is prepared from phthalaldehyde, alcohol, metallic ion chelating agent, non-ionic surfactant, pH regulator or buffer, and water. Its advantages are no poison and irritation to human body, high effect and stability, and low cost.

Description

technical field [0001] The present invention relates to a kind of disinfectant, more particularly, the present invention relates to a kind of disinfectant containing o-phthalaldehyde. Background technique [0002] Although there are many disinfectants on the market that can reach the level of sterilization and high-efficiency disinfection, each of them has certain disadvantages, such as: peroxides have poor stability and strong corrosion; alkylates are highly toxic and safe; Chlorine and bromine are highly corrosive and irritating; aldehydes (formaldehyde, glutaraldehyde) have certain toxicity and irritation, and the disinfection effect and stability are easily affected by the pH value. Sterilization takes a long time and other disadvantages. Therefore, bring a lot of inconvenience to the disinfection of hospital clinic and other industries. [0003] Western developed countries such as the United States, Canada, the United Kingdom, and France developed o-phthalaldehyde (En...
