Пиролиз провод т при атмосферном давлении в проточной системе путем пропускани исход 1ого реагента или смеси исходных реагентов через нолую кварцевую или металлическую трубку при температуре 650-750°С со скоростью, обеспечивающей врем пребывани в реакционной зоне в пределах 10- 100 сек.Pyrolysis is carried out at atmospheric pressure in a flow system by passing the first reagent or a mixture of initial reagents through a new quartz or metal tube at a temperature of 650-750 ° C with a rate ensuring a residence time in the reaction zone within 10-100 seconds.
Пример 1. В пустую кварцевую или металлическую трубку (диаметр 28 мм, длина 600 мм) пропущеио 16,5 г (0,05 моль) о-хлорфенил- (сс-нафтил) -дихлорсилана при темиературе со скоростью, обеспечивающей вреExample 1. In an empty quartz or metal tube (diameter 28 mm, length 600 mm), 16.5 g (0.05 mol) of o-chlorophenyl- (cc-naphthyl) -dichlorosilane were passed through at a speed that allowed
