Tris(ethylmethylamido)(tert-butylimido)tantalum(V) - Introduction
Tris(ethylmethylamido)(tert-butylimido)tantalum(V), TEMATa for short, is an organic tantalum compound with the following properties:
1. Appearance: TEMATa is colorless to light yellow crystal or liquid.
2. Melting point: The melting point of TEMATa is 75-77 degrees Celsius.
3. Solubility: TEMATa is soluble in some organic solvents, such as alkanes, aromatics and ketones.
4. Stability: TEMATa is relatively stable in dry air, but it will decompose with moisture.
TEMATa is mainly used for material deposition in chemical vapor deposition (CVD) processes. It can be used as a metal organic precursor for the preparation of tantalum or tantalum thin films, coatings and other related materials.
The preparation method of TEMATa is complicated and generally involves a multi-step reaction. One common method is by the reaction of tert-butylimine and ethylformamide with tantalum (V) chloride.
regarding the safety information of TEMATa, it should be noted that:
1. Activity: TEMATa is an active organic compound that needs to be stored and processed under moisture-proof and nitrogen protection.
2. Toxicity: Because TEMATa may produce toxic gases and vapors during the chemical process, it is necessary to pay attention to necessary safety measures, such as good ventilation and wearing appropriate personal protective equipment.
3. Hot: TEMATa may be flammable, avoid contact with open flames and high heat sources, and keep away from oxidants.
4. chemical instability: TEMATa will decompose and produce harmful gases under humid conditions, so it is necessary to avoid contact with water and moisture.
In order to use the safety of TEMATa, it is recommended to understand and follow the relevant safety operating procedures and operating guidelines when using it in a laboratory or industrial production environment. If necessary, professional guidance and advice should be sought.
