Method of removing formaldehyde with vinegar

Vinegar is a very common thing in people's lives. It is mainly used in the kitchen. Vinegar is of great help to our lives. Vinegar can be used to remove tea stains and to cure athlete's foot. In fact, vinegar can also remove formaldehyde, especially in rooms with strong formaldehyde after decoration. Using vinegar to remove formaldehyde has unexpected effects. Here is a detailed description of the effectiveness of vinegar in removing formaldehyde.

Formaldehyde often appears when a house is being decorated. After we move in, formaldehyde will be very harmful to our body. Some people say that formaldehyde can be removed with vinegar, but in fact, this method is not feasible. Using vinegar to remove formaldehyde is just a folk method. It does not really remove the formaldehyde. Vinegar just suppresses the smell of formaldehyde.

1. When we decorate the house, a lot of harmful gases will be left behind, not just formaldehyde. Although from a chemical point of view, vinegar can react with formaldehyde, vinegar is not volatile, while formaldehyde is volatile, so the probability of the two combining is very low, so it is not very useful to us.

2. If we really want to remove formaldehyde from our home, we can simply open the windows and then ventilate. This is the most hygienic and environmentally friendly method, but we have to wait relatively longer.

Formaldehyde is a colorless gas with a strong irritating odor. Soluble in water, alcohol and ether. Formaldehyde is a gas at room temperature and usually appears in the form of an aqueous solution. A 35-40% formaldehyde aqueous solution is called formalin. The aldehyde group in the formaldehyde molecule undergoes condensation reaction to produce phenolic resin (Bakelite). The main hazard of formaldehyde is its irritation to the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Formaldehyde concentration greater than 0.08m3 can cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc. You can refer to the "Mutong Three-Step Formaldehyde Removal Method" for treatment.

Formaldehyde is an important organic raw material, mainly used in the plastics industry (such as phenolic resin, urea-formaldehyde plastic - electroplating), synthetic fibers (such as synthetic vinylon - polyvinyl formal), leather industry, medicine, dyes, etc. Formalin has bactericidal and preservative capabilities and can be used to soak biological specimens. Its dilute solution (0.1-0.5%) can be used in agriculture to soak seeds and disinfect them. Catalytic oxidation is commonly used in industry to produce formaldehyde from methanol. Formaldehyde can produce a silver mirror reaction with silver ammonia solution, causing a thin layer of shiny metallic silver like a mirror to adhere to the inner wall of the test tube (the combined silver is reduced and the formaldehyde is oxidized); it reacts with freshly prepared copper hydroxide suspension to form red precipitated cuprous oxide.
