Description
Technical field
The present invention relates to a kind of application test amplifying devices, and in particular to a kind of hexamethyldisiloxane prepares answering for silicone oil
With experiment amplifying device.
Background technology
Low viscosity methyl-silicone oil uses DMC and hexamethyldisiloxane（Abbreviation MM）It is urged in storng-acid cation exchange resin
It is prepared under change effect, but for the hexamethyldisiloxane of trial production, in order to which it is examined to prepare the qualification of silicone oil, removes
Outside the lab scale of laboratory, need to be verified using experiment is further amplified.
Invention content
To solve the above problems, the present invention provides the application apparatus that a kind of hexamethyldisiloxane prepares silicone oil.
The specific technical solution of the present invention is as follows：
A kind of device that silicone oil is prepared using hexamethyldisiloxane, including raw material storage tank, reaction kettle, packed tower, rotor
Pump, condenser, low molecule storage tank, raw material storage tank at the top of feed pipe and reaction kettle by connecting, and reactor bottom is through conveying pipeline
Connect with rotary discharge valve, rotary discharge valve divides two-way after being connect with impeller pump, after being connect all the way with packed tower again with reaction kettle
Top connects, and forms circulation loop, directly forms circulation loop with being connect at the top of reaction kettle all the way.
It is connect at the top of the reaction kettle through conveying pipeline with condenser overhead, condenser bottom is stored up through conveying pipeline and low molecule
Tank connects.
Both ends install filter cloth and card additional on the inside of the packed tower, and filter cloth is set on the inside of card.
A kind of device that silicone oil is prepared using hexamethyldisiloxane, workflow are：Reaction kettle is vacuumized so that
Raw material storage tank metering DMC enters through feed pipe in reaction kettle, stops vacuumizing, and to reaction kettle heating stirring, low molecule is stored up
Tank vacuumizes, and DMC dehydrations, low molecule enters low molecule storage tank by condenser, after dehydrating amount reaches a certain level, stops taking out true
Sky, reaction kettle feed inlet manually add in needed for MM, be stirred, heating preheating, be then turned on reaction kettle by impeller pump with
The circulation loop that packed tower is formed, the DMC mixed and MM are squeezed into packed tower, are reacted certain time, and timing sampling measures
Silicon oil viscosity after viscosity reaches required standard, closes the circulation loop.Reaction kettle is opened to follow self by what impeller pump was formed
Loop back path vacuumizes low molecule storage tank, reaction kettle heating, carries out de- low, after de- low amounts reaches a certain level, stops taking off
It is low.Reaction is completed.
Advantages of the present invention：The scale-up of silicone oil is prepared suitable for hexamethyldisiloxane, it is simple and feasible, solve reality
The problem of room amplification condition is limited is tested, the production for hexamethyldisiloxane provides application test device.
