preparation example Construction

[0036] The preparation method of the phthalaldehyde disinfectant comprises mixing various components in raw materials.

[0037] In one embodiment, the method of mixing the components in the feedstock comprises:

[0038] Mix flux, complexing agent, corrosion inhibitor, penetrant, and o-phthalaldehyde into deionized water at a temperature of 40-60°C, mix well and cool to room temperature to obtain the first mixture;

[0039] Adding a foam suppressor and a pH buffer to the first mixture to obtain a second mixture, the pH of the second mixture is 7.5-8.5;

[0040] The second mixture was filtered and the filtrate was collected.

[0041] Further, the mixed method is realized by following the sequence of steps:

[0042] Step 1. Add deionized water into the mixing tank and heat to 40°C-60°C.

[0043] Step 2: Add 1%-15% co-solvent and stir for 30 minutes.

[0044] Step 3: adding 0.1% to 5% complexing agent and stirring for 30 minutes.

[0045] Step 4, adding 0.1% to 2% of corrosio...

Embodiment 1

[0065] The formula of o-phthalaldehyde disinfectant is as follows: o-phthalaldehyde 0.5%, co-solvent 1%, complexing agent 0.1%, penetrant 0.1%, corrosion inhibitor 0.1%, foam suppressor 0.1%, pH buffer 0.1% , the balance of deionized water.

[0066] The production method is as follows: Step 1. Add deionized water into a stirring tank and heat to 40°C. Step 2: Add co-solvent and stir for 30 minutes. Step 3, add complexing agent, stir for 30 minutes. Step 4: Add corrosion inhibitor and stir for 30 minutes. Step five, add penetrating agent, stir for 60 minutes, step six, add o-phthalaldehyde, stir for 60 minutes. Let stand to room temperature. Step 7, adding antifoaming agent and stirring for 30 minutes. Step 8, adding a pH buffering agent to make the pH value 7.5. Stir for 60 minutes. Step 9: Set aside to settle for 60 minutes, filter and fill.

[0067] The o-phthalaldehyde disinfectant formula in embodiment 2~embodiment 6 is as shown in table 3.

Abstract

The invention relates to an o-phthalaldehyde disinfectant and a preparation method thereof, belonging to the field of disinfection products. The o-phthalaldehyde disinfectant is prepared from the following components by mass percent: 0.5-5% of o-phthalaldehyde, 1-15% of a cosolvent, 0.1-5% of a complexing agent, 0.1-2% of a penetrant, 0.1-2% of a corrosion inhibitor, 0.1-5% of a foam inhibitor, 0.1-5% of a pH buffer agent and the balance of deionized water. The o-phthalaldehyde disinfectant provided by the invention is soft in smell, is almost tasteless, and is free from corrosiveness, high inoxidation resistance and good in stability. The life cycle is increased to 28 days from 14 days, so that the durable years of medical equipment is effectively prolonged, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of disinfection products, in particular to an o-phthalaldehyde disinfectant and a preparation method thereof. Background technique [0002] Ortho-phthalaldehyde (OPA) is an important pharmaceutical and chemical intermediate, which was mainly used in amine alkaloids, fluorometer histamine determination reagents and medical inspection in the past. Since Alaf et al. used it for endoscope disinfection in 1994 and found that it has a good disinfection effect, many studies have been carried out on the disinfection of OPA abroad, and it has been developed into a new type of high-efficiency disinfectant and passed the US FDA certification. . [0003] Compared with the disinfectant glutaraldehyde, o-phthalaldehyde has the advantages of broad-spectrum glutaraldehyde, high efficiency, and low corrosion. It also has its own characteristics such as less irritation and low concentration. In addition, OPA also has a good killing e...
