Problems solved by technology

[0003] However, because formic acid has a pungent smell and is corrosive, human beings will experience skin and mucous membrane irritation symptoms after contact with it, and cause conjunctivitis, eyelid edema, rhinitis, bronchitis, and severe cases can cause acute chemical pneumonia
Moreover, concentrated formic acid aqueous solution can corrode the oral cavity and digestive tract mucosa after oral administration, causing vomiting, diarrhea and gastrointestinal bleeding, and even death due to acute renal failure or respiratory failure.
Therefore, the application of formic acid is restricted

Embodiment 1

[0037] The embodiment of the present invention provides a kind of preparation method of softening formic acid aqueous solution, specifically comprises the following steps:

[0038] In the first step, the formic acid aqueous solution with a mass concentration of 60% and the calcium lignosulfonate aqueous solution with a mass concentration of 92% are uniformly mixed in a liquid mixing tank to obtain a mixed solution; wherein, the formic acid aqueous solution and the calcium lignosulfonate aqueous solution The volume ratio is 1:0.5.

[0039] In the second step, the mixed solution was transferred to a twin-screw machine, and mixed at 25° C. for 2 hours to obtain a softened formic acid aqueous solution.

Embodiment 2

[0041] The embodiment of the present invention provides a kind of preparation method of softening formic acid aqueous solution, specifically comprises the following steps:

[0042] In the first step, the formic acid aqueous solution with a mass concentration of 60% and the calcium lignosulfonate aqueous solution with a mass concentration of 92% are uniformly mixed in a liquid mixing tank to obtain a mixed solution; wherein, the formic acid aqueous solution and the calcium lignosulfonate aqueous solution The volume ratio is 1:1.

[0043] In the second step, the mixed solution was transferred to a twin-screw machine, and mixed at 25° C. for 2 hours to obtain a softened formic acid aqueous solution.

Embodiment 3

[0045] The embodiment of the present invention provides a kind of preparation method of softening formic acid aqueous solution, specifically comprises the following steps:

[0046] In the first step, the formic acid aqueous solution with a mass concentration of 60% and the calcium lignosulfonate aqueous solution with a mass concentration of 92% are uniformly mixed in a liquid mixing tank to obtain a mixed solution; wherein, the formic acid aqueous solution and the calcium lignosulfonate aqueous solution The volume ratio is 1:1.5.

[0047] In the second step, the mixed solution was transferred to a twin-screw machine, and mixed at 25° C. for 2 hours to obtain a softened formic acid aqueous solution.

Abstract

The invention provides a softened formic acid aqueous solution, a preparation method therefor, a disinfectant and application and belongs to the field of material treatment. The corrosion property andvolatilization property of formic acid are lowered on the premise of not affecting application of the formic acid, so that adverse effects on health of human bodies caused by the formic acid are reduced. The preparation method for the softened formic acid aqueous solution comprises the step of mixing a calcium lignosulfonate aqueous solution and a formic acid aqueous solution to form an intermolecular hydrogen bond between calcium lignosulfonate and formic acid, so as to obtain the softened formic acid aqueous solution. The softened formic acid aqueous solution is prepared by adopting the preparation method. The softened formic acid aqueous solution provided by the invention is applied to disinfectants.

Description

technical field [0001] The invention belongs to the field of material processing, and in particular relates to a softened formic acid aqueous solution, a preparation method thereof, a disinfectant and an application thereof. Background technique [0002] Formic acid (chemical formula HCOOH, molecular formula CH2O2, molecular weight 46.03), commonly known as formic acid, exists in the secretions of bees, certain ants and caterpillars. It is a basic organic chemical raw material and is widely used in pesticides, leather, dyes, medicine and Rubber and other industries. Formic acid can be directly used in fabric processing, leather tanning, textile printing and dyeing and green fodder storage, and can also be used as metal surface treatment agent, rubber auxiliary and industrial solvent. [0003] However, because formic acid has a pungent smell and is corrosive, human beings will experience skin and mucous membrane irritation symptoms after contact with it, and cause conjunctiv...
