Tetraisocyanatosilane - Introduction
Tetraisocyanatosilane(Tetraisocyanatosilane) is an organosilicon compound whose chemical formula is Si(NCO)4. The following is a description of its nature, use, preparation and safety information:
Nature:
-The Tetraisocyanatosilane is a colorless to yellow liquid with a pungent odor.
-It has high vapor pressure, is volatile, insoluble in water, and soluble in organic solvents, such as petroleum ether.
- Tetraisocyanatosilane is a highly active chemical reagent, reactive with water, alcohols, amines and other compounds containing active hydrogen.
Use:
- Tetraisocyanatosilane is widely used as an intermediate for organosilicon compounds, and can be used to prepare a variety of functionalized organosilicon compounds in organic synthesis, such as amide interaction reagents, formal reagents, etc.
-It can also be used to prepare organic polymers with isocyanate groups, polyurethane and polyurea and other polymers.
Preparation Method:
-The common synthesis method of Tetraisocyanatosilane is obtained by silane alkylation reaction.
-The specific synthesis method is to react a compound containing an active cyano group with chloromethyl triisocyanate (also known as methyl isocyanate) to obtain Tetraisocyanatosilane.
Safety Information:
- Tetraisocyanatosilane has a pungent smell, direct contact with skin and eyes should be avoided.
-In handling and storage, should take appropriate protective measures, wear protective gloves, glasses and protective clothing.
-Avoid contact with water, alcohols, amines and other active hydrogen compounds, avoid reaction, so as not to cause danger, and maintain a well-ventilated working environment.
-Observe relevant safety procedures and regulations during use and disposal.
