Abstract

The invention relates to an o-phthalic aldehyde disinfectant and a preparation method thereof. The disinfectant adopts D-isoascorbyl aldehyde acetal as the antioxidant, and comprises the following components in percentage by weight: 0.3 to 1.0% of o-phthalic aldehyde, 0.02 to 0.2% of D-isoascorbyl aldehyde acetal, 0.1 to 2.0% of buffering agent, 0.2 to 2.0% of chelating agent, 0.05 to 5.0% of corrosion inhibitor, and the balance being water. The preparation method comprises the following steps: according to the components and contents mentioned above, adding o-phthalic aldehyde into water, stirring to dissolve the o-phthalic aldehyde, orderly adding D-isoascorbyl aldehyde acetal, buffering agent, chelating agent, and corrosion inhibitor, and stirring to dissolve so as to obtain the o-phthalic aldehyde disinfectant. The added D-isoascorbyl aldehyde acetal has a high-effective antioxidant effect, moreover has stable properties and low toxicity, and is capable of prominently improving the stability and safety of o-phthalic aldehyde.

Description

technical field [0001] The invention relates to an o-phthalaldehyde disinfectant, in particular to a novel high-efficiency and safe antioxidant iso-Vc acetal (ketone) used in the o-phthalaldehyde disinfectant. Background technique [0002] Ortho-phthalaldehyde (OPA) is a broad-spectrum, high-efficiency, and low-corrosion new type of disinfectant. It was used in endoscope disinfection in foreign countries in 1994, and it was found to have a good disinfection effect. In 1999, o-phthalaldehyde was certified by the US FDA as a high-level disinfectant for repeated treatment of heat-sensitive medical equipment. However, there are also obvious disadvantages in o-phthalaldehyde, which is unstable in nature and easily destroyed by oxidation. [0003] Iso-Vc acetal (ketone) is formed by the acetalization or ketalization of iso-Vc and C6-C12 straight-chain saturated fatty aldehyde, cyclohexanone, benzaldehyde or cinnamaldehyde. The carbonyl group in the aldehyde and ketone molecule r...
