1,1-CYCLOPENTANEDIACETIC ACID - Introduction
3,3-tetramethyleneglutaric acid, also known as TMEDA(N,N,N',N'-tetramethylethylenediamine) dicarboxylate, is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: TMEDA is a colorless to yellow liquid.
-Density: Its density is low, about 0.948g/cm³.
-Boiling point: The boiling point of TMEDA is about 140-141°C.
-Solubility: It can be dissolved in many organic solvents and form complexes with many organometallic compounds.
Use:
-Ligand: TMEDA is commonly used as a ligand for coordination compounds. It can form stable complexes with metals and participate in organic synthesis, catalytic reactions and preparation of coordination polymers.
-Catalyst: Because the nitrogen atom of TMEDA has a lone pair of electrons, it can form a pair with metal and catalyze a variety of organic reactions, such as oxidation, addition, cyclopentylation, etc.
-Polymerization inhibitor: TMEDA's conductive properties and odor characteristics make it a polymerization inhibitor in polyol-based polyurethane products.
Method:
-TMEDA can usually be obtained by The transesterification reaction between dicarbonate and N,N-dimethylethylenediamine. The reaction is generally carried out under an inert atmosphere at an appropriate temperature.
Safety Information:
- TMEDA is irritating and corrosive, avoid contact with skin and eyes. During use, pay attention to take necessary personal protective measures, such as wearing gloves and masks, and operate in a well-ventilated place.
-Be sure to avoid contact with organics, oxidants and strong acids during storage and handling.
-If inhaled, ingested or exposed to this compound, remove it immediately to fresh air and, if necessary, seek medical attention.
Please note that the above information is for reference only. When using and handling chemicals, follow proper laboratory practices and consult a professional if necessary.
