BACKGROUND OF THE INVENTION Organosilanols, which are useful as plasticizers for silicone rubbers and intermediates for the synthesis of various silicone compounds, are Si
It is well known that it can be obtained by a hydrolysis reaction of an organosilicon compound having a —H bond, and has been widely used conventionally for the production of organosilanols. Although some catalysts that accelerate this hydrolysis reaction are known, carbon or alumina supporting a transition metal such as palladium, rhodium, and platinum is generally used. For example, a reaction of hydrolyzing triethylsilane (Et 3 SiH) in the presence of ruthenium-carbon to obtain triethylsilanol (Et 3 SiOH) at a yield of 87% is the Journal of Organic Chemist.

When an organosilicon compound having a plurality of Si-H bonds is hydrolyzed by the same method, the corresponding polysilanol is obtained, but the yield is lowered. This is because the transition metal component is physically adsorbed on carbon, so some of the transition metal component is dropped into the reaction system, which promotes condensation between polysilanols having higher reactivity than monosilanol. This is because. In this case, condensation between polysilanols occurs even if the pH of the reaction system is adjusted with a pH buffer solution. Further, when the produced polysilanol is purified by distillation from the reaction mixture, the polysilanol condensation occurs due to the synergistic effect of the transition metal component dropped from the catalyst and heating, and the isolation yield is significantly reduced.

In this hydrolysis reaction, the organosilicon compound having the Si—H bond of the above formula (1) is reacted with a theoretical equivalent amount of water or more in the presence of the above catalyst. Further, this reaction can be carried out usually in the range of ambient temperature to about 100 ° C. Preferably 40-70 ° C
Range. Further, this reaction can be carried out without a catalyst, but it is preferably carried out in the presence of a suitable solvent.
Of these, aprotic polar solvents such as tetrahydrofuran, diethyl ether, acetone, ethyl acetate, dimethylsulfoxide, dimethylformamide are preferable. Further, since this catalyst is a solid, the above reaction can be carried out in a batch system or a continuous system. When the reaction is carried out in a batch system, after completion of the reaction, the catalyst can be separated by a separation operation such as filtration, and the catalyst can be directly recycled to the next reaction. Also, when carrying out the reaction in a continuous system,
It can be carried out by passing a mixture of the Si—H bond-containing organosilicon compound, water, and a solvent over or in the catalyst bed. The amount of the catalyst used is not particularly limited, but is 0.1 to 2000 pp as the amount of palladium.
It is preferably m. After the above hydrolysis, the catalyst can be separated by filtration and the desired organosilanol can be isolated by vacuum distillation according to a conventional method. In this case, in the present invention, silanol does not condense during this vacuum distillation, and the target organosilanol can be obtained in high yield. The catalyst separated by filtration can be used repeatedly.
