22984-54-9 Usage
Application
Methyltris(methylethylketoxime)silane is used as a neutral curing agent in silicone sealant formulations. Generally, this silane is used for crosslinking α,ω-silanol polydimethylsiloxanes in the presence of atmospheric moisture.
It is often the main crosslinker of choice for oxime silicone sealants and can be used by itself or in combination with other oxime silanes to provide the sealant with targeted properties (such as desired cure rate, adhesion etc).
Chemical Properties
Colorless or yellowish transparent liquid
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 22984-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,8 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22984-54:
(7*2)+(6*2)+(5*9)+(4*8)+(3*4)+(2*5)+(1*4)=129
129 % 10 = 9
So 22984-54-9 is a valid CAS Registry Number.

Paragraph 0013, (2016/12/01)
The invention belongs to the technical field of fine chemistry and relates to a methyltris(methylethylketoxime)silane preparation method.Methyltrimethoxysilane, diacetylmonoxime and p-toluenesulfonic acid which serves as a catalyst react according to a certain proportion, excessive diacetylmonoxime in the reaction process serves as a solvent to make the reaction more thorough and easier, and methanol is recovered during reaction. After reaction is finished, the diacetylmonoxime which serves as the solvent is recovered by reduced pressure distillation, and the recovered diacetylmonoxime can be recycled.Products obtained by distillation are washed and filtered to obtain high-purity methyltris(methylethylketoxime)silane. The methyltris(methylethylketoxime)silane preparation method has the advantages that product yield is above 97%, product content is above 98%, materials can be recycled completely, no waste liquid is generated, and accordingly environment pollution is avoided.
