186038-82-4 - Introduction
Diethylene (1-CYANO-3-METHYLBUTYL)MALONATE is an organic compound commonly abbreviated as EMCM. The following is a description of its nature, use, formulation and safety information:
Nature:
-Appearance: EMCM is a colorless to light yellow liquid.
-Solubility: EMCM is soluble in many organic solvents, such as ethanol, acetone and dichloromethane.
-Melting point: The melting point of EMCM is between -10 and -15 degrees Celsius.
-Density: The density of EMCM is about 1.03 g/ml.
Use:
- EMCM is often used as an intermediate in organic synthesis. It can be used to synthesize complex organic compounds such as pharmaceuticals, pesticides and dyes.
- EMCM can also be used as a catalyst stabilizer for protection.
-Because EMCM is stable under regular reaction conditions, it has a wide range of applications in organic synthesis.
Method:
The synthesis of-EMCM is generally carried out by ethoxylation, cyanation and carboxylic acid esterification reactions.
-First, 2-methylhexanoic acid ester is reacted with an acid catalyst to form 2-hydroxy-3-methylhexanoic acid ester.
-Then, by reacting with sodium cyanide, 2-hydroxy-3-methylhexanoate is converted to 2-methyl-3-cyanohexanoate.
-Finally, 2-methyl-3-cyanohexanoate is reacted with ethanol to generate DIETHYL (1-CYANO-3-METHYLBUTYL)MALONATE.
Safety Information:
- EMCM is irritating and direct contact with skin, eyes and respiratory tract should be avoided.
-Adequate ventilation measures should be taken during operation, and personal protective equipment, such as gloves and protective glasses, should be worn.
- EMCM should be stored in a cool, dry place and avoid contact with fire.
Please note that, as with all chemical substances, EMCM should be used or handled in accordance with the correct safety practices, and risks should be assessed and controlled on a case-by-case basis.
