It can be used to add chemical materials to improve some properties of chemical materials; in catalytic reaction, it can be used to assist in catalytic equivalence to promote the reaction.
What are the physical properties of Hexamethyldisilazane?
Hexamethyldisilazane, it is an organosilicon compound. It has unique physical properties and is worth exploring.
Looking at its properties, it is a colorless and transparent liquid under normal conditions, and has a faint amine smell. Its boiling point is about 126 ° C. This characteristic makes it possible to separate and purify by distillation under specific temperature conditions. The melting point is about -78 ° C. The lower melting point makes it capable of maintaining a liquid state in a relatively low temperature environment, which is easy to operate and use.
Hexamethyldisilazane density is about 0.77g/cm ³, which is lighter than water and immiscible with water. It can be clearly identified in stratification experiments. Its solubility also has characteristics, soluble in most organic solvents, such as ether, toluene, etc., so that it can well disperse the reactants in the organic synthesis reaction system and promote the smooth progress of the reaction.
And because its molecular structure contains silicon-nitrogen bonds, it has certain chemical stability. When exposed to water or moisture, it is easy to hydrolyze and release ammonia. This chemical property is also related to its storage and use conditions. It needs to be protected from water, moisture, and stored in a dry place.
Its vapor pressure is low at room temperature and volatilization is relatively slow, which is beneficial to the safety of the operating environment and the maintenance of product purity. In the field of organic synthesis, it is often used as a silanizing reagent to introduce a specific molecular structure through its silane group to change the physical and chemical properties of the molecule, and is widely used.
What is the chemistry of Hexamethyldisilazane?
Hexamethyldisilazane (hexamethyldisilazane), it is one of the organosilicon compounds. It is active and has unique chemical properties.
Looking at its chemical structure, it contains a silicon-nitrogen bond (Si-N), which gives it specific reactivity. At room temperature, it is a colorless and transparent liquid, smells like ammonia, is volatile, flammable, and should avoid open flames and hot topic environments.
In terms of its reaction characteristics, hexamethyldisilazane can be used as a silanizing agent. In the field of organic synthesis, it often reacts with compounds containing active hydrogen, such as alcohols, phenols, carboxylic acids, etc. Taking alcohol as an example, it interacts with hexamethyldisilazane, and the hydroxyl hydrogen of the alcohol is replaced by a silane group to form a silicon ether compound. This reaction can be used to protect the hydroxyl group from being affected under specific reaction conditions. After the reaction is completed, the silane group is removed by an appropriate method and the hydroxyl group is restored.
In the nucleophilic substitution reaction, the silicon nitrogen negative ion produced by hexamethyldisilazane has nucleophilic properties and can react with electrophilic reagents such as halogenated hydrocarbons to form products containing silicon-carbon bonds. And because of the connection of multiple methyl groups on the silicon atom, the steric resistance is large, which can affect the reaction selectivity in some reactions.
In addition, hexamethyldisilazane is sensitive to water and air. It is easy to hydrolyze in contact with water, and the silicon-nitrogen bond breaks, releasing ammonia gas, and generating silanol or polysiloxane by-products. Therefore, when storing and using, it must be kept in a dry environment, isolated from water vapor and air, and often operated in an inert gas atmosphere, such as nitrogen and argon.
What is Hexamethyldisilazane production method?
hexamethyldisilazane, that is, hexamethyldisilazane. The method of preparation is usually to react with ammonia gas in trimethylchlorosilane.
Prepare a reaction kettle, place an appropriate amount of trimethylchlorosilane in it, and introduce dry ammonia gas. When the two meet, they chemically react. During the process, the chlorine atom of trimethylchlorosilane combines with the hydrogen atom in ammonia to form ammonium chloride, and the remaining part is polymerized to synthesize hexamethyldisilazane. The reaction formula is roughly as follows: 2 (CH 🥰) < SiCl + 2NH 🥰 → [ (CH 🥰) < Si] < NH + 2NH Cl.
When reacting, it is necessary to pay attention to control the temperature and pressure. If the temperature is too high, side reactions will easily occur, resulting in impure products; if the temperature is too low, the reaction rate will be slow and take a long time. Generally speaking, the temperature should be controlled within a moderate range to enable the reaction to proceed smoothly and efficiently. The pressure cannot be ignored, and the appropriate pressure environment will help the reaction to advance.
After the reaction is completed, the product is often mixed with impurities such as ammonium chloride. A suitable method of separation and purification is required to obtain pure hexamethyldisilazane. The solid ammonium chloride is often removed by filtration, and then the product is further purified by distillation and other means. According to the different boiling points, hexamethyldisilazane is separated from the mixture to obtain a pure product.
What are the precautions when using Hexamethyldisilazane?
Hexamethyldisilazane, it is also a silicone compound. Many matters need to be paid attention to when using it.
First, this substance is volatile, has a pungent smell and is toxic to a certain extent, so it should be operated in a well-ventilated place, or with the help of ventilation equipment, to avoid excessive inhalation, damage to the respiratory system, dizziness and nausea.
Second, Hexamethyldisilazane is easy to hydrolyze in contact with water, generating ammonia and silicone alcohol substances. When storing and using, be sure to keep the environment dry and avoid contact with water vapor to prevent deterioration and affect the use effect.
Third, it is flammable, and open flames and hot topics should be strictly prohibited at the operation site. Keep away from fire and heat sources to prevent fire and explosion. And it should be properly stored in a cool, dry and ventilated place, away from oxidants, acids and other substances, because it may react violently with it.
Fourth, when operating, you need to wear appropriate protective equipment, such as protective glasses, gloves, protective clothing, etc. If you accidentally touch the skin or eyes, you should immediately rinse with a lot of water. If the situation is serious, you need to seek medical treatment immediately.
Fifth, after use, the remaining reagents and waste should be properly disposed of in accordance with regulations, and do not dump them at will, so as not to pollute the environment.
All these are important items to pay attention to when using Hexamethyldisilazane, so as to ensure the safe and smooth operation and play its due effect.
