preparation example Construction

[0072] As a particular embodiment, the biocyntal disinfectant preparation method comprises: adding ethanol and a cleaved to 100 g of water to stir well, and then add a biorelade, bio-based surfactant to stir well. The addition of appropriate amount of water is mixed, and the acid-base reagent is added to adjust the pH to obtain a disinfectant of the biological aldehyde.

[0073] Preparation method of surfactant:

[0074] Surfactant I: 1 mmol 2,5-dihydroxymethylfuran, 1 mmol oil alcohol, 5 ml 1, 4-dioxane, and 40% by weight ITQ-2 (silicone atom ratio) Take 15, prepared according to Nature 1998, 396, 353-356). Heat was stirred from the oil bath to 100 ° C for 10 h. After the reaction was completed, cooled to room temperature and filtered out the catalyst. Separation was separated by column chromatography, the reaction solution was eluted with petroleum ether and ethyl acetate (a volume ratio of 10: 1), and the solvent was evaporated.

[0075] Surfactant II: 1 mmol of 5-hydroxymethyl...

Embodiment 1

[0081] 20 g of ethanol and 12.5 g of 1-octene-3-alcohol were added to 100 g of water, and 25 g of furfural, 37.5 g of surfactant I was mixed, and then water 55 g was mixed, and the acid-base reagent was added to 8.5. It can obtain a sterilizing agent of the biological aldehyde. Among the acid base reagent is ammonia water.

[0082] In the disinfectant, the content of ethanol was 8% by weight, 1-octene-3-alcohol was 5 wt%, and the content of furfural was 10% by weight, and the content of surfactant I was 15 wt%, and the rest was water.

Embodiment 2

[0084] 25 g of ethanol and 7.5 g of ionol were added to 100 g of water and stirred evenly, and 12.5 g 2,5-dimethylfricumfuran was added thereto, and the 50 g of surfactant II was mixed well, and 55 g of water was mixed, and the acid-base reagent was adjusted to adjust the pH. 6.0, the biocyntal disinfectant can be obtained. Among acid base reagents are ammonium chloride.

[0085] In the disinfectant, the content of ethanol is 10% by weight, the content of the decanool is 3 wt%, and the content of 2,5-dimethylfffuran is 5 wt%, and the content of the surfactant II is 20 wt%, and the rest is water.

Abstract

The invention discloses a bio-based disinfectant and a preparation method thereof. The bio-based disinfectant contains bio-based aldehyde, a biological surfactant, low-carbon alcohol, an odor removing agent and water, wherein the pH of the disinfectant is 3.0 to 10.0. The bio-based aldehyde disinfectant provided by the invention has the characteristics of high efficiency, low toxicity, small corrosion, good stability and the like, is non-volatile, can also avoid causing extra steam hazards, and is expected to be widely applied to multi-scene disinfection and sterilization.

Description

Technical field [0001] The present application relates to a bio-based disinfectant and a preparation method, which belongs to the field of chemical disinfection. Background technique [0002] The aldehyde disinfectant is a kind of efficient and low toxic disinfectant, which is widely used in farming, food processing equipment and utensil disinfection, environmental and object surface disinfection. [0003] Existing aldehyde disinfectants include petroleal aldehyde disinfectant glutaraldehyde. [0004] Traditional petroleal aldehyde disinfectant glutaraldehyde, etc., which can cause bronchitis and pulmonary edema, must be strictly controlled and cannot be used in conventional places. Inventive content [0005] According to one aspect of the present application, a disinfectant of a biological aldehyde is provided, and the biocyntal disinfectant has high efficiency, low toxicity, small corrosion, good stability, etc., it is not volatile, and it can also avoid additional steam.
