Abstract
The invention relates to a device for preparing silicone oil from hexamethyldisiloxane. The device comprises a raw material storage tank, a reaction kettle, a packed tower, a rotor pump, a condenser and a low-molecule storage tank, wherein the raw material storage tank is connected with the top of the reaction kettle through a feeding pipeline; the bottom of the reaction kettle is connected with a rotary discharging valve through a conveying pipe; the rotary discharging valve is divided into two paths after being connected with the rotor pump, one path is sequentially connected with the packed tower and the top of the reaction kettle to form a circulation loop, and the other path is directly connected with the top of the reaction kettle to form a circulation loop. The device is applicable to the scale-up test for preparing silicone oil from hexamethyldisiloxane and is simple, convenient and feasible; the problem that the scale-up condition in a laboratory is limited is solved, and an application test device is provided for the production of hexamethyldisiloxane.
Description
Technical field
This
inventionrelate to a kind of application test multiplying arrangement, be specifically related to the application test multiplying arrangement that a kind of hexamethyldisiloxane prepares silicone oil.
Background technology
Low viscosity methyl-silicone oil adopts DMC and hexamethyldisiloxane (being called for short MM) to be prepared under storng-acid cation exchange resin katalysis, but for the hexamethyldisiloxane of trial production, in order to the qualification checking it to prepare silicone oil, except the lab scale of laboratory, need to adopt further scale-up to verify.
Summary of the invention
For solving the problem, this
inventionprovide the application apparatus that a kind of hexamethyldisiloxane prepares silicone oil.
This
inventionconcrete technical scheme as follows:
a kind of device adopting hexamethyldisiloxane to prepare silicone oilcomprise raw material storage tank, reactor, packing tower, rotor pump, condenser, low molecule storage tank, raw material storage tank is connected with reactor top by feed pipe, be connected with rotary discharge valve through carrier pipe bottom reactor, after rotary discharge valve is connected with rotor pump, point two-way, is connected with reactor top after a road is connected with packing tower again, forms circulation loop, one tunnel is directly connected with reactor top, forms circulation loop.
Described reactor top is connected with condenser overhead through carrier pipe, is connected bottom condenser through carrier pipe with low molecule storage tank.
Inside described packing tower, two ends install filter cloth and card additional, and filter cloth is arranged at inside card.
a kind of device adopting hexamethyldisiloxane to prepare silicone oil, its workflow is: vacuumize reactor, making raw material storage tank measure DMC enters in reactor through feed pipe, stopping vacuumizes, to reactor heated and stirred, low molecule storage tank is vacuumized, DMC dewaters, low molecule enters low molecule storage tank by condenser, after dehydrating amount acquires a certain degree, stopping vacuumizes, required MM is manually added at reactor opening for feed, be uniformly mixed, intensification preheating, then the circulation loop that reactor is formed by rotor pump and packing tower is opened, DMC and MM mixed is squeezed in packing tower, reaction certain hour, timing sampling measures silicon oil viscosity, after viscosity reaches required standard, close this circulation loop.Open the circulation loop that reactor self is formed by rotor pump, vacuumize low molecule storage tank, reactor heats up, and carries out de-low, after de-low amounts acquires a certain degree, stops de-low.Reaction completes.
This
inventionadvantage: be applicable to the scale-up that hexamethyldisiloxane prepares silicone oil, simple and feasible, solve laboratory and amplify the limited problem of condition, the production for hexamethyldisiloxane provides application test device.
