The numerous areas such as Fei Pin.
Industrial organosilicon product is the mixture of a variety of degrees of functionality, wherein with the dosage of dimethyldichlorosilane most
Greatly, 90% (mass fraction) of methylchlorosilane is accounted for.There are many modes for producing methylchlorosilane, and modernization industry is all adopted
It is produced in batches with direct synthesis technique, it is the direct synthesizing methyl by chloromethanes and silica flour under the action of heating and catalyst
The method of chlorosilane.The maximum difficult point of organosilicon production is the synthesis of monomer, and improving the efficiency of synthesis and reducing cost is
The eternal problem in the field.Influence organic silicon monomer synthesis yield and diformazan selectivity, except process units, material quality and
Outside synthesis technology, catalyst is its key factor.
The prior art and report have proven to the most effective catalyst that copper is current direct synthesis methylchlorosilane, but
It is only not enough to obtain good effect by the use of copper as catalyst, it generally all can compound wherein or the other auxiliary of addition member
Element, the activity as Zn-ef ficiency can improve reaction increase yield, and the pick-up rate that tin element can improve dimethyldichlorosilane (is called
" diformazan selectivity "), P elements can reduce the occurrence probability of side reaction, and oxygen element extends reaction time and stablizes reaction process.One
A little researchers have manufactured acid bronze alloy catalyst by adding in the elements such as phosphorus, and this catalyst is during production application
It is selectively not sufficiently stable for the activity and diformazan of reaction, the performance in particular for different silicon ore raw materials is unstable, diformazan
The scope of selectivity is between 75~90%, and for fluctuation range more than 15%, entire reaction process fluctuation is very big, is unfavorable for reacting
The control and operation of process.
