Formaldehyde with the chemical formula CH2O has several names such as formaldehyde, methanal, methylene oxide and methyl aldehyde. It exists as a gas at ambient temperature, but has the ability to dissolve in water. In fact, formalin is an aqueous solution of formaldehyde with a concentration of 37% and formalin 42%, which is the general use of this substance in industry and agriculture.

One of the models of using formalin is Samed formalin 37% and samed formalin 42%

Formalin dissolves well in water and produces Samed formalin 37% and samed formalin 42%. Formalin in polymerized water contains small HCHO monomers bonded together. Usually Samed formalin 37% and samed formalin 42% contain a small percentage of methanol to limit polymerization. Formaldehyde has the same properties as other aldehydes. It is usually more reactive than other aldehydes.

Formalin was first discovered by a Russian scientist named Alexander Butler in 1859. This gas is easily created by the incomplete combustion of carbon-containing compounds. In the smoke from forest fires, large volumes of formaldehyde enter the atmosphere. Apart from this, car exhaust fumes, cigarette smoke and factory fumes also contain large amounts of formalin. Formalin is naturally obtained in the atmosphere from the reaction of oxygen with methane and other hydrocarbons by sunlight. The metabolism of some hydrocarbons also produces small amounts of formalin.

 

But in industry, methanol reacts with air in the presence of formaldehyde catalysts. Samed formalin 37% and samed formalin 42% is one of the most important forms of formaldehyde.

Production method of Samed formalin 37% and samed formalin 42%:

 The raw material for formalin production is 37% and formalin is 42% methanol. Methanol evaporates rapidly and after mixing with oxygen in the air produces an explosive gas that is used to prevent the dangers of transporting and storing methanol, fire extinguishers, and tanks equipped with refrigerants. In the Samed formalin 37% and samed formalin 42% production unit, methanol is first converted to superheated steam by heat, then mixed with air oxygen in a certain ratio and passed through a catalyst bed at a temperature of 300 ° C. After passing the gas mixture through the catalyst, formaldehyde gas is produced in the reactor unit. Formaldehyde gas along with nitrogen gases, carbon dioxide and water vapor leave the reactor and after cooling is directed into the adsorption tower. Due to the contact, the water stream of formaldehyde in the gas is absorbed and Samed formalin 37% and samed formalin 42% solution is formed, which is kept in the lower part of the tower and after cooling, it is directed into the storage tanks. In total, 37% of formalin and 42% of formalin are produced in the industry by catalytic oxidation of methanol. If iron oxide and molybdenum are used as catalysts, methanol reacts with oxygen at 300 ° C to form Samed formalin 37% and samed formalin 42%.

Safety tips when using formalin 37% and formalin 42%

Samed formalin 37% and samed formalin 42% are absorbed through the skin and are very carcinogenic. Samed formalin 37% and samed formalin 42% have been used in the past in washing and dishwashing liquids due to their preservative and antimicrobial properties, but fortunately Its use is currently prohibited. Its alternatives include isothiazoline, which has a European safety standard.

Employees should observe the following points when working with Samed formalin 37% and samed formalin 42%:

Work with Samed formalin 37% and samed formalin 42% should be done in a well-ventilated area.

Oral pipetting of Samed formalin 37% and samed formalin 42% is prohibited.

Smoking, eating and drinking are prohibited where Samed formalin 37% and samed formalin 42% are stored.

When working with Samed formalin 37% and samed formalin 42%, wear thick plastic gloves, lab coats, and closed-toe shoes and wear goggles or face goggles.

In case of eye or skin contact with Samed formalin 37% and samed formalin 42%, be sure to rinse the eye or the desired area with large amounts of water for 15 minutes.

Samed formalin 37% and samed formalin 42% should be kept away from hydrochloric acid because the combination of its vapor with hydrochloric acid creates a very strong carcinogen called dichloromethyl ether.

Samed formalin 37% and samed formalin 42% should be kept away from heat.
