4-氧代戊酸 钙盐 - Introduction
levulinic acid calcium salt dihydrate is an inorganic salt with the chemical formula Ca(C5H8O3)2 · 2H2O. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
levulinic acid calcium salt dihydrate is a water-soluble white crystalline solid. It has a density of 1.32g/cm³ and a melting point of 140-144°C. Under heating, the compound loses water of crystallization and is converted to an anhydrous salt.
Use:
levulinic acid calcium salt dihydrate have a variety of uses in the chemical industry. It can be used as a catalyst for organic synthesis, especially in oxidation reactions. In addition, it can also be used as an electrolyte and metal surface treatment agent in the electroplating industry.
Preparation Method:
levulinic acid calcium salt dihydrate can be obtained by reacting levulinic acid with calcium oxide. First, levulinic acid is dissolved in water, then calcium oxide suspension is added, and the precipitate generated by the reaction is levulinic acid calcium salt dihydrate. Finally, the precipitate is dewatered and dried to obtain the target product.
Safety Information:
levulinic the toxicity of acid calcium salt dihydrate to human body is low, it is still necessary to pay attention to safe operation. Avoid inhalation of dust and contact with skin, eyes and respiratory tract during operation. In case of contact, rinse immediately with plenty of water and seek medical help. Avoid contact with acids and flammable substances during storage and handling.
