What are the physical properties of Trimethyl Orthoformate?
Trimethoxymethane, also known as trimethyl orthoformate, is a colorless and transparent liquid with a pungent odor. Its physical properties are many and quite important.
Looking at its properties, it is a colorless and transparent liquid under normal circumstances, with a pungent smell and easy to smell. Regarding the melting point, it is about -53 ° C. At this temperature, it will change from liquid to solid. The boiling point is 102 ° C. When heated to this temperature, it will boil and change from liquid to gas.
Besides the density, at 20 ° C, the density is about 0.96 g/cm ³, which is slightly lighter than water. Its solubility also has characteristics. It can be miscible with various organic solvents such as ethanol and ether, but slightly soluble in water. This characteristic determines its behavior in different solvent systems.
In addition, the vapor pressure of trimethoxymethane is also worth mentioning. At a specific temperature, it has a certain vapor pressure, which affects its existence in the gas phase. And because of its strong volatility, it is volatile in the air, so it should be paid attention to when operating.
These physical properties of trimethoxymethane have a profound impact on its application in chemical industry, organic synthesis and other fields. Due to its boiling point, solubility and other characteristics, it is often used as a solvent or participates in reactions in organic reactions, providing conditions for the progress of many chemical reactions.
What are the chemical properties of Trimethyl Orthoformate?
Trimethoxymethane, commonly known as trimethyl orthoformate, has unique chemical properties and is worth exploring.
This substance is a colorless, transparent and pungent odor liquid with a moderate boiling point of about 102 ° C, a relative density lighter than water, and can be miscible with various organic solvents such as alcohols and ethers.
Trimethyl orthoformate has a high degree of chemical activity. During the hydrolysis reaction, it decomposes slowly in contact with water to form methyl formate and methanol. This reaction is more likely to occur in a humid environment, because moisture prompts the rearrangement of carbon-oxygen bonds in its molecular structure.
Alcoholysis reaction is also an important property. Under specific conditions, alcohol exchange reactions with alcohols can occur to generate new orthoformate and methanol. This reaction is significantly affected by catalysts, and some metal salts or organic bases can effectively accelerate the reaction process.
Trimethyl orthoformate also exhibits good condensation properties. With compounds containing active hydrogen, such as aldose and ketone, under appropriate conditions, condensation reactions can occur to generate many compounds with special structures. For example, when reacted with aldose, it can form a carbadide structure product. Such reactions are widely used in the field of organic synthesis and are often used to construct complex organic molecular structures.
Because of its unique chemical properties, trimethyl orthoformate is an important reagent in organic synthesis. It is widely used in the preparation of fine chemical products such as medicines, pesticides, and dyes. It helps the synthesis of many important organic compounds, which is of great significance to the development of the chemical industry.
What is the production method of Trimethyl Orthoformate?
Trimethyl acetal, or trimethyl orthoformate, is prepared by ancient methods and modern methods.
Ancient production methods mostly used orthoformic acid and methanol as raw materials to combine the two under specific conditions. Although orthoformic acid is difficult to find, it was an important route when the chemical process was not complete in the past. At that time, fine temperature and pressure control were required to make the reaction proceed smoothly, and the containers and instruments used also needed to meet the reaction requirements to prevent impurities from mixing and affecting the purity of the product.
As for the current production method, chloroform and sodium methoxide are commonly used as starting materials. Chloroform reacts with sodium methoxide in a suitable solvent. This reaction condition is easier to control, and the yield and purity of the product are significantly improved. At the beginning of the reaction, chloroform is slowly dropped into the solution containing sodium methoxide, and the temperature and reaction process are closely monitored. Sodium methoxide plays a key role in the reaction, and its alkalinity prompts chloroform to undergo a specific substitution reaction to gradually generate trimethylal. After the reaction is completed, pure trimethylal can be obtained through multiple purification processes such as distillation and extraction.
Another method is to use methyl formate and methanol as raw materials. Under the action of catalysts, the condensation reaction of the two occurs. The choice of this catalyst is quite important, and different catalysts have a significant impact on the reaction rate and product selectivity. During the reaction process, it is necessary to precisely adjust the temperature, pressure and raw material ratio to achieve the best reaction effect. Follow-up steps such as separation and purification are also required to remove unreacted raw materials and by-products to obtain high-quality tri-methylal.
