Description

Известен способ получени  треххлористого фосфора хлорированием раствора фосфора в треххлористом фосфоре, Однако при этом наблю перегревы реакционной массы, усложн ющие технологию производства .A known method for producing phosphorus trichloride is the chlorination of a solution of phosphorus in phosphorus trichloride. However, in this case, we observed overheating of the reaction mass, complicating the production technology.

Предлагаемый способ отличаетс  тем, что процесс ведут с подачей хлора и фосфора в раздельные аппараты и отвод тепла реакции осуществл ют флегмированием хлоратора с помощью выносного теплообменника . Это интенсифицирует процесс и делает его более безопасным.The proposed method is characterized in that the process is carried out with the supply of chlorine and phosphorus to separate units and the heat of reaction is removed by refluxing the chlorinator using an external heat exchanger. This intensifies the process and makes it safer.

При осуществлении способа раствор фосфора в треххлористом фосфоре обрабатывают газообразным хлором при температуре сч;80° с подачей хлора и фосфора в раздельные аппараты.In the process, a solution of phosphorus in phosphorus trichloride is treated with chlorine gas at a temperature of 80 ° C with the supply of chlorine and phosphorus to separate units.

Технологическа  схема производства треххлористого фосфора состоит из следующих элементов.The technological scheme for the production of phosphorus trichloride consists of the following elements.

Фосфор из емкости с полющью центробежного насоса подаетс  в емкость с растворителем, откуда центробежным насосом раствор фосфора в треххлористом фосфоре подаетс  в хлоратор.Phosphorus from the tank with a centrifugal pumping pump is fed into the tank with a solvent, from where a centrifugal pump supplies a solution of phosphorus in phosphorus trichloride to the chlorinator.

Часть раствора сливаетс  обратно в емкость растворител . Содержание фосфора в подаваелюм в хлоратор растворе составл ет 10-12%, в сливаемом - 6-9%. Хлорирование ведут при температуре 80-82° и давлении 0,1-0,2 ати. Съем тепла ведут флегмированием хлоратора треххлористым фосфором через колонну и дефлегматор. Отгон поступает на систему дохлорнровани  и разгонку.A portion of the solution is drained back into the solvent container. The phosphorus content in the supply in the chlorinator solution is 10-12%, in the merged - 6-9%. Chlorination is carried out at a temperature of 80-82 ° and a pressure of 0.1-0.2 MPa. Heat removal is carried out by refluxing a chlorinator with phosphorus trichloride through a column and a reflux condenser. The distillation is fed to the re-chlorination and distillation system.

Непрерывный способ получени  треххлористого фосфора хлорированием фосфора в треххлористом фосфоре, отличающийс  тем. что, с целью интесификации и безопасности процесса, его ведут с подачей хлора и фосфора в раздельные аппараты и отвод тепла реакции осуществл ют флегмированпем хлоратора с помощью выносного теплообменника .A continuous process for the preparation of phosphorus trichloride by the chlorination of phosphorus in phosphorus trichloride, characterized in that. that, for the purpose of intensification and safety of the process, it is carried out with the supply of chlorine and phosphorus into separate apparatus and the heat of reaction is removed by flushing a chlorinator using an external heat exchanger.
