Giới thiệu

Sodium formate, also known as sodium methanoate, is a white, odorless, crystalline solid with the chemical formula CH2O2Na. It is a salt of formic acid and has a melting point of 250°C. Sodium formate is a common industrial chemical that is used in a variety of applications, including:

Food preservation: Sodium formate is used as a preservative in foods such as processed meats, cheese, and fruit juices. It helps to prevent the growth of bacteria and mold.

Chemical synthesis: Sodium formate is used as a starting material in the synthesis of a variety of chemicals, including pharmaceuticals, polymers, and pesticides.

Water treatment: Sodium formate is used to treat water in swimming pools and other aquatic facilities. It helps to control algae growth and improve water clarity.

Dạng muối natri

Của cải

Dạng muối natri is a hygroscopic compound, meaning that it absorbs moisture from the air. It is also a weak base, with a pKa of 3.75. Sodium formate is soluble in water and ethanol, but it is insoluble in most other organic solvents.

Sự an toàn

Dạng muối natri is generally considered to be safe for use in food and industrial applications. However, it can be harmful if ingested in large quantities. Symptoms of sodium formate poisoning include nausea, vomiting, diarrhea, and abdominal cramps. In severe cases, sodium formate poisoning can lead to seizures, coma, and death.

Production

Dạng muối natri is produced by the reaction of formic acid with sodium hydroxide:

HCOOH + NaOH → CH2O2Na + H2O

This reaction can be carried out in either an aqueous or non-aqueous solvent.
