Evonik (formerly Degussa AG) HMDS, organic silane coupling agent Dynasylan HMDS Hexamethyldisilazane Overview:

Dynasylan ®HMDS  (Hexamethyldisilazane) silylating agent is developed and produced by Evonik Degussa AG, used in the pharmaceutical industry as an adhesion aid for microelectronics and as a hydrophobic agent (such as filler). Dynasylan ® HMDS is a colorless liquid.

 Dynasylan ® HMDS Hexamethyldisilazane Characteristics:

Dynasylan ® HMDS hexamethyldisilazane is commonly used as a silylation reagent for organic and inorganic materials. Dynasylan ® HMDS Hexamethyldisilazane Reactivity: Dynasylan ® HMDS hexamethyldisilazane can react with some protonated substances, such as alcohols, phenols, carboxylic acids, amino acids, hydrocarbons, thiols, and amines. And generate silyl derivatives by eliminating ammonia. The siliconization reaction is usually carried out by adding an equal or excessive amount of Dynasylan ® HMDS hexamethyldisilazane is carried out under reflux conditions until ammonia is no longer generated. Suitable solvents are ethanol and phenol. Adding catalysts such as sulfuric acid or ammonium sulfate can accelerate the reaction rate and degree. Dynasylan ® HMDS and trimethylchlorosilane mixed in a 1:1 molar ratio are effective silylating reagents for 3 molar amounts of reactants. The silylation of Dynasylan ® HMDS hexamethyldisilazane is usually carried out under solvent-free conditions. The yield of the silylation reaction is usually very high and can often be quantified. Dynasylan ® HMDS decomposes under water or acid conditions. Strong oxidants can cause oxidation reactions.

Evonik (formerly Degussa AG) HMDS, organic silane coupling agent Dynasylan HMDS Hexamethyldisilazane Packaging specifications:

Evonik (formerly Degussa AG) HMDS, an organic silane coupling agent Dynasylan HMDS, is mainly used in the following applications:

 Used as a hydroxyl blocking and protective agent in some natural products (further obtaining stable products and volatile products).

 As a functional group blocking and protecting agent in organic intermediates, siliconized derivatives are obtained, which have better chemical stability and cause some chemical reactions that are usually impossible to occur compared to the original compounds.

 Derivatives (silyl derivatives) that can be used for proton compounds are analyzed by gas chromatography.

 The sealing agent can be removed by hydrolysis, which has a very high yield. In some cases, it is also possible to achieve the effect of removing the sealing agent by heating. The silylation reaction of inorganic substances, especially silicates (such as silica), is used as fillers in polymers. Its hydrophobic effect is beneficial for better dispersion system, reducing viscosity and better adhesion. The silylation reaction of metals or metalloids (silicon) is beneficial for the hydrophobic and adhesive effects of polymers (Hard plastic or thermoplastic).
