What are the physical properties of O-Aminobenzotrifluoride?

O-Aminotrifluorotoluene is one of the organic compounds. Its physical properties are quite interesting, and are described in detail below.

Looking at its appearance, under room temperature and pressure, it often takes the form of a colorless to light yellow transparent liquid, just like clear amber, shimmering and flashing, with unique charm.

Smell it, but it has a special smell. This smell is not pleasant, but it has a strong recognition. It is unforgettable to smell, but it is not long to smell, because it may be irritating.

When it comes to boiling point, it is between one hundred and ninety and ninety-two degrees Celsius. When the temperature approaches this value, the force between molecules is gradually overcome, and the material changes from liquid to gaseous state, just like breaking a cocoon into a butterfly, and the shape changes abruptly.

Its melting point is about minus 15 degrees Celsius. When the outside temperature drops to this value, the thermal movement of molecules slows down, and the arrangement between them becomes orderly. The flowing liquid gradually turns into a solid state, just like the time of solidification.

In terms of density, it is about 1.36 grams per cubic centimeter. Compared with the density of water, it is slightly thicker. If it is placed in the same place as water, it will sink underwater, like a treasure hidden under the water.

Solubility is also an important property. In organic solvents such as ethanol, ether, dichloromethane, etc., O-aminotrifluorotoluene can dissolve well, just like a fish entering water, and it fuses seamlessly. However, in water, its solubility is very small, and the two seem to be distinct and difficult to fuse.

These physical properties are of key significance in many fields such as organic synthesis, medical chemistry, etc., laying the foundation for related research and applications.

What is the chemistry of O-Aminobenzotrifluoride?

O-trifluorotoluene (O-Aminobenzotrifluoride) is also an organic compound. Its color is light yellow to brown liquid, with a unique odor. The melting point of this substance is quite characteristic, the melting point is about -15 ° C, the boiling point is 227-228 ° C, and it can maintain stability at room temperature and pressure.

In terms of solubility, it is insoluble in water, but it is easily soluble in organic solvents such as ethanol, ether, acetone, etc. This characteristic is due to the difference between its molecular structure and the forces between water molecules and organic solvent molecules.

The chemical properties of o-amino trifluorotoluene are active, and the presence of amino groups (-NH _ 2) and trifluoromethyl groups (-CF _ 3) gives it special reactivity. Amino groups are basic and can react with acids to form corresponding salts. At the same time, amino groups can participate in many nucleophilic substitution reactions, such as reacting with halogenated hydrocarbons to form new carbon-nitrogen bonds, and then derive a series of nitrogen-containing organic compounds.

The presence of trifluoromethyl groups is a strong electron-absorbing group, which reduces the electron cloud density of the benzene ring, changes the electrophilic substitution activity on the benzene ring, and often makes the reaction more inclined to meta-substitution. This compound can also participate in the diazotization reaction, and a variety of fluorinated aromatic compounds can be prepared by further transformation of diazotide intermediates, which have important application value in the fields of drug synthesis, pesticide creation and material science.

What is O-Aminobenzotrifluoride production method?

O-aminotrifluorotoluene is an important intermediate in organic synthesis. There are roughly several ways to prepare it.

One is to use o-nitrotrifluorotoluene as the starting material and obtain it by reduction. It is often obtained by iron powder, zinc powder and other metals in an acidic medium, interacting with o-nitrotrifluorotoluene, and the nitro group is reduced to an amino group. This is a classic chemical reduction method. However, this method has many side reactions, and the resulting metal salt waste is not easy to dispose of.

The second is catalytic hydroreduction method. Using palladium carbon, platinum carbon, etc. as catalysts, under a hydrogen atmosphere, o-nitrotrifluorotoluene is hydrogenated, and the nitro group is converted into an amino group. This method has the advantages of high selectivity, good yield, environmental friendliness, and less waste generation. Nowadays, industrial production is more inclined to this method.

It is also prepared by the aminolysis reaction of o-halogenated trifluorotoluene and ammonia under suitable catalysts and reaction conditions. Among them, the halogen atom is replaced by an amino group to form O-amino trifluorotoluene. However, it is necessary to choose suitable halogenate, catalyst and control the reaction temperature, pressure and other conditions to improve the reaction efficiency and selectivity.

All methods have their own advantages and disadvantages. In actual production, it is necessary to comprehensively consider the availability of raw materials, cost, environmental protection and many other factors to select the best preparation route.

What are the precautions in storage and transportation of O-Aminobenzotrifluoride?

O-Aminotrifluorotoluene is an important raw material for organic synthesis. During storage and transportation, many matters need to be paid attention to.

Its properties are flammable and corrosive. When storing, place it in a cool and ventilated warehouse. The temperature of the warehouse should not be too high, and it must be kept away from fire and heat sources to prevent it from volatilizing and burning due to excessive temperature. When the lighting and ventilation facilities of the warehouse are explosion-proof, the switch should be located outside the warehouse to avoid ignition caused by electric sparks.

Storage containers should also be carefully selected, and corrosion-resistant materials, such as special steel or plastic materials, should be used to prevent the container from being corroded and leaking. And the container must be tightly sealed, do not mix air, water vapor, etc., because the substance may react with some components in the air, or deteriorate due to moisture.

During transportation, the same cannot be slack. Transportation vehicles must meet relevant safety standards and be equipped with corresponding fire equipment and leakage emergency treatment equipment. During transportation, ensure that the container does not leak, collapse, fall, or damage. It should be stored separately from oxidants, acids, alkalis, etc. Do not mix and mix, or react violently with such substances, causing danger.

The loading and unloading process should be handled lightly to prevent damage to the packaging and containers. Handlers should wear protective clothing, protective gloves and goggles to ensure their own safety. In case of accidental leakage, personnel from the contaminated area should be quickly evacuated to a safe area and quarantined to strictly restrict access. Emergency responders must wear self-contained positive pressure breathing apparatus and anti-toxic clothing to cut off the source of leakage as much as possible to prevent it from flowing into restricted spaces such as sewers and flood drains.

All of these are for the storage and transportation of O-aminotrifluorotoluene.
