Trifluoromethane - Nature
Open Data Verified Data
colorless, odorless, non-combustible. Normal temperature is the liquefied gas. Liquid density 1.442g/mL(-80 C), the critical temperature of 25.7. The solubility was 0.10% by weight at 25 °c and 0.1 MPa. Slightly soluble in water, soluble in ethanol, ketone, ether, benzene, carbon tetrachloride, insoluble in ethylene glycol and glycerol. It is an inactive substance with chemical properties, which can react with nitrogen trioxide (N2 03) at 1 70 ℃ and with fluorinated nitrous acid (NOF) at 1 00 ℃. Slow photochemical chlorination can be performed, but photochemical bromination cannot occur. In case of high fever, the internal pressure of the container increases, and there is a risk of cracking and explosion. Contact with barium, calcium, strontium, and magnesium powders and oxides of these metals can react vigorously. Corrosion of magnesium and its alloys. Decomposition occurs when exposed to heat or contact with alkaline earth metals (such as barium, calcium, strontium, and magnesium) and alkali metals (such as lithium, sodium, potassium, rubidium, cesium, and strontium).

Trifluoromethane - Application
Open Data Verified Data
The electronic-grade fluorine analog is one of the plasma etching gases widely used in the microelectronics industry, especially for the etching of silicon dioxide film, which has the advantages of fast etching speed and good selectivity. In addition, fluoride is also used for low temperature mixed refrigerant, organic synthesis intermediates, infrared detector direct coolant, etc.

Trifluoromethane - Safety
Open Data Verified Data
after contact can be Head Pain, Nausea and Vomit, and the role of anesthesia. Can be regarded as low toxic or non-toxic gas, high concentration of anesthesia, and combustible gas combustion decomposition to produce toxic fluoride. When poisoning is found, the victim should be removed from the contaminated area, keep warm, use artificial respiration if necessary, and immediately seek medical treatment. Non-combustible compressed gas. Store in a cool, ventilated warehouse. The bin temperature should not exceed 30 ℃. Keep away from fire and heat source. Protection from direct sunlight. Should be stored separately from flammable and combustible materials.

Trifluoromethane - Introduction
trifluoromethane, the chemical formula CF3CH, also known as fluoraltane or r23. The following is a description of its nature, use, preparation and safety information:
Nature:
1. trifluoromethane is a colorless, odorless, non-toxic gas with a higher density than air.
2. It has high stability and insulation performance, and is not easy to burn.
3. trifluoromethane has low temperature properties and will directly become solid under normal pressure.
Use:
1. The main application of trifluoromethane is as a refrigerant and fire extinguishing agent. Because of its high efficiency, non-toxic, non-polluting and non-combustible characteristics, it is widely used in refrigeration equipment, air conditioning systems and fire fighting systems.
2. trifluoromethane is also used as a cleaning agent and desiccant in the electronics industry.
Preparation Method:
1. trifluoromethane can be prepared by reacting Liquid fluorine with hydrogen fluoride. The catalyst needs to be added during the reaction.
2. In addition, trifluoromethane can also be synthesized from fluorine gas and trifluoroboron.
Safety Information:
1. trifluoromethane is a stable compound that is not prone to explosion or combustion.
2. Prolonged exposure to trifluoromethane may irritate the eyes and skin. Wear protective gloves and glasses during operation.
3. trifluoromethane is a strong greenhouse gas, which has a destructive effect on the atmospheric ozone layer and should be avoided from being released into the atmosphere.
Please note that when using and handling trifluoromethane, please refer to relevant safety procedures and local regulations.
