Cyclopropanecarboxylic acid, 1-cyano- - Introduction
Acid is an organic compound with the chemical formula C5H5NO2. It is a solid powder with a bitter taste. The following is a description of some of the properties, uses, methods of manufacture and safety information about the acid:
Nature:
-must acid is insoluble in water, but can be dissolved in organic solvents such as ethanol and dimethylformamide.
-Its melting point is 139-141°C, and its boiling point is 192°C.
-the acid can undergo a condensation reaction to form a cyclic acrylonitrile and an imine of a carboxylic acid.
Use:
-acid is commonly used as a reagent in organic synthesis. It can be used as an intermediate in the synthesis of drugs, pesticides and other organic compounds.
-It can also be used to synthesize polymer materials with special properties.
Preparation Method:
-or acid can be obtained by reacting cyclopropyl carboxylic acid with cyanide. First, cyclopropyl carboxylic acid is condensed with triethylamine and dimethylformamide to form carboxylic acid ester, then sodium cyanide or potassium cyanide is added for cyanation reaction, and then hydrolyzed to obtain acid.
Safety Information:
-acrylic is an irritating compound that may cause irritation in contact with the skin and eyes.
-when using and operating acid, wear protective gloves, goggles and protective mask to ensure a well-ventilated experimental environment.
-When storing, place it in a sealed container and keep it away from fire and oxidizing agents.
