R2CNa

R2CNa, also known as R2C2Na, is a chemical compound with the formula R2CNa, where R represents an alkyl or aryl group. It is a sodium salt of a carboxylic acid, specifically a sodium carboxylate. The compound is characterized by its sodium ion (Na+) bonded to a carboxylate group (R2C-O2-).

R2CNa is typically prepared through the neutralization reaction of a carboxylic acid with sodium hydroxide (NaOH). This reaction results in the formation of the sodium salt and water. The sodium carboxylate salts are often used in various industrial applications, including as surfactants, emulsifiers, and dispersants in the production of textiles, paints, and coatings.

The properties of R2CNa can vary depending on the specific alkyl or aryl group attached to the carboxylate group. For example, sodium stearate (R = CH3(CH2)16-) is a common sodium carboxylate used in the production of soaps and detergents due to its ability to form stable emulsions.

In summary, R2CNa is a versatile sodium carboxylate salt with applications in various industries. Its properties and uses can be tailored by selecting appropriate alkyl or aryl groups.
