Description

Известен способ непрерывного получепи  фенилтрихлорсилана из бепзола п трихлорсилана при нагревании и давлепии.There is a known method of continuous preparation of phenyltrichlorosilane from bepzol and trichlorosilane with heating and pressure.

Описываемый способ по сравнепию с известным повыгнает выход фенилтрихлорсилана и производительность оборудовани .The described method, by comparison with the known, will release the output of phenyltrichlorosilane and the equipment capacity.

Особенность способа состоит в том, что в реакционную массу непрерывно добавл ют дихлорсилан.A feature of the process is that dichlorosilane is continuously added to the reaction mass.

Пример I. 3975 г бензола и 3259 г трихлорсилана с примесью 3%дихлор;силана (мол рное соотношение 2,1 : I) нагревают в автоклаве при 450° и давлении 141 ати в течение 4 час. Получают 1680 г фенилтрихлорсилана , что составл ет выход 32,2%.Example I. 3975 g of benzene and 3259 g of trichlorosilane mixed with 3% dichloro, silane (molar ratio 2.1: I) are heated in an autoclave at 450 ° and a pressure of 141 MPa for 4 hours. Phenyltrichlorosilane 1680 g is obtained, which gives a yield of 32.2%.

Пример 2. 3975 г бензола и 3259 г трихлорсилана с примесью 3% дихлорсилана нагревают при 450° и давлении 180 ати в течение 4 час. Получают 1780 г фенилтрихлорсилана (выход 35,2%).Example 2. 3975 g of benzene and 3259 g of trichlorosilane with an admixture of 3% dichlorosilane are heated at 450 ° and a pressure of 180 atm for 4 hours. 1780 g of phenyltrichlorosilane are obtained (yield 35.2%).

Пример 3. 4000 г бензола и 3084 г трихлорсилана с примесью 3% дихлорсилана (мол рное .соотношение 2,25: 1) нагревают при 450° и давлении 150 ати в течпие 4 час. Получают 1690 г фени. трихлорсилана (выход 35,2%).Example 3. 4000 g of benzene and 3084 g of trichlorosilane with an admixture of 3% dichlorosilane (molar ratio 2.25: 1) are heated at 450 ° and a pressure of 150 MPa for 4 hours. Get 1690 g of feni. trichlorosilane (yield 35.2%).

Пример 4. Смесь бензола и трихлорсилана с примесью 2-4% дихлорсилана в весовом соотношении I : 0,87 (мол рное соотношение 2:1) нагнетают дозируюшим насосом высокого давлени  в реактор , в котором поддерживают температуру 440-460° и давление 140- 180 ати. Скорость подачи реакштонной смеси 9,5-10 л/час. Реакцию ведут 4 часа. В сконденсированном, Быход ш,ем из реактора, продукте содержитс  22,5-25% по весу фенилтрихлорсилана (выход 33-36%).Example 4. A mixture of benzene and trichlorosilane mixed with 2-4% dichlorosilane in a weight ratio of I: 0.87 (molar ratio 2: 1) is injected into the reactor with a high-pressure dosing pump, in which the temperature is maintained at 440-460 ° and the pressure is 140- 180 ati. The feed rate of the mixture is 9.5-10 l / h. The reaction is 4 hours. In the condensed, by-product from the reactor, the product contains 22.5-25% by weight of phenyltrichlorosilane (yield 33-36%).
