As a result of intensive research on the production of aryldihalosilanes by the disproportionation reaction of aryldihalosilanes as described above, the present inventors found that the disproportionation reaction The present inventors have discovered that reducing the pressure in the reaction system is extremely effective in obtaining the desired diaryldihalosilane in a high yield, leading to the completion of the present invention. That is, the present invention is a method for producing a desired diaryldihalosilane in a high yield, which is characterized in that the disproportionation reaction of an aryldihalosilane is carried out under reduced pressure conditions.

Compounds that are a combination of these are preferred. In other words, aryl groups include phenyl groups, alkali groups such as tolyl and ethylphenyl groups, halogenated phenyl groups such as chlorophenyl and fluorophenyl groups, trifluoromethyl groups, phenoxyphenyl groups, and biphenyl groups. Examples include groups or groups substituted with alkyl and/or halogen. Further, as the halogen group, a chlorine atom is most preferable, but a bromine atom and a fluorine atom can also be mentioned.

０．０１〜５重都％が好ましい。The catalyst used in the disproportionation reaction of the present invention may be a conventionally known metal halide Lewis acid compound, but aryl metal Lewis acid compounds may also be suitably used. However, since the present invention is characterized in that it is carried out under reduced pressure, it is naturally desirable to use a catalyst substance that is difficult to remove from the reaction system even under reduced pressure. Examples include aluminum halides such as aluminum chloride, and arylboranes such as triphenylborane and tritolylborane. These catalysts can be used in an amount of 0.0001 to 10% by weight, preferably 0.01 to 5% by weight, based on the raw material aryldihalosilane.

反応方式も採用している。As the method for the disproportionation reaction in the present invention, conventionally known methods can be suitably employed as they are, except that the reaction is performed under reduced pressure conditions. In other words, the most suitable method is a batch reaction method in which the raw material aryldihalosilane and the catalyst are charged into a reactor and heated and stirred. A flow reaction method is also adopted in which the reaction is carried out while the reaction is being carried out.

圧の程度にあることから特に限定されず、通常はｆ５０
℃以上の条件が採用される。The optimum reaction temperature varies depending on the type of aryldihalosilane used as a raw material and the catalyst, but since the more important factor is the degree of pressure reduction, it is not particularly limited, and is usually set at f50.
℃ or higher conditions are adopted.
反応時間も特に限定されないが、数１０分〜ｌＯ数時間

ｒである。Basically, the higher the degree of reduced pressure, the more the disproportionation reaction is accelerated, but it is also important that the raw material aryldihalosilane comes into sufficient contact with the catalyst dissolved in the liquid phase. There are also limits to the degree of pressure reduction. The limit varies depending on the type of ary-dihalosilane and the reaction temperature, but is usually 0,0 OITorr or more, preferably 0,'0ITorr or more. When reducing pressure within this limit, there is a characteristic that the effect of reduced pressure becomes more pronounced as the degree of reduced pressure is higher at the same temperature, and that it becomes more pronounced under conditions of lower pressure reduction at high temperatures. However, there is often a tendency to obtain the desired diaryldihalosilane in a much higher yield under conditions of a high degree of vacuum at low temperatures;

It is r.

しく妨げる作用をしていると推測される。The above disproportionation reaction was carried out using phenyldichlorosilane (PhSi
(H)C1lz) is used as a raw material. In this reaction, 2PhSi (H)CQ
4' 7=P h 2 S i CQ 2 + H2
As shown in S i CQ, 2, the target product is diphenyldichlorosilane (denoted as Ph2S i CQ z).This reaction is originally considered to be an equilibrium reaction, so if the reaction had reached an equilibrium state, diphenyldichlorosilane The amount of dichlorosilane produced becomes constant at a certain amount, and no further increase can be expected. Therefore, extracting the by-product dichlorosilane (H2SiCQ, denoted as 2) from the system will increase the amount of acid produced. However, since the boiling point of dichlorosilane is extremely low at 8°C at normal pressure, if the disproportionation reaction is carried out at a high temperature of 185°C, which is around the boiling point of phenyldichlorosilane, dichlorosilane will naturally dissolve in the reaction liquid. It is expected that it will be easily removed from the phase. However,
Despite the high temperature of 185°C, the disproportionation reaction does not proceed much. On the other hand, since the effect of reduced pressure is actually noticeable, conversely, it is possible that dichlorosilane, which is difficult to remove at normal pressure even at a high temperature of 1115°C, exists in the liquid phase. . Moreover, even if the reaction temperature is as low as 80°C, the disproportionation reaction proceeds more quickly under conditions of high vacuum of several Torr, so the forward and reverse reaction rate of the disproportionation reaction is the same. is quite large even at low temperatures, but the equilibrium constant of the reaction is extremely small, so it is assumed that the presence of even a very small amount of dichlorosilane in the liquid phase has the effect of significantly inhibiting the increase in the production of diphenyldichlorosilane. be done.
