Uses
1.Trimethyl orthoacetate is an important intermediate for the synthesis of methyl dichlorochrysanthemate.
2.It is an intermediate used in the production of medicine and pesticide, and is also the main raw material for the production of food additives, coatings, paints, etc. It is used as an organic synthesis reagent.
3.Fine chemical industry: Trimethyl orthoacetate is also widely used in fine chemical industry, including dyestuff and spice industry. It is a colourless and transparent liquid with mild fragrance, commonly used in the process of polymer preparation, such as polyvinyl alcohol, polyether, polyester, polyurethane and so on.
4.Cosmetic, food, spice industry.
Trimethyl orthoacetate is chemically stable, but it is stable in alkaline media and unstable and decomposes when it meets water and acidic media, decomposing mainly acetic acid and methanol when it meets water. This chemical property determines its applicability and limitation in certain chemical reactions. Therefore, when using trimethyl orthoacetate, it is necessary to pay attention to avoid contacting with organic and inorganic acids and water to prevent the unstable decomposition reaction.
In summary, as an important organic compound, trimethyl orthoacetate has a wide range of applications in the chemical industry, especially in the synthesis of pharmaceuticals and pesticides plays an important role.
