Description
Technical field
The utility model is related to chemical industry synthesis field, is exactly a kind of synthesizer of polymethoxy dimethyl ether.
Background technology
Polymethoxy dimethyl ether, also known as polyoxymethylene dimethyl ether, polyoxymethylene dimethyl ethers, polymethoxy methylal, are one
The common name of class material, its skeleton symbol can be expressed as：CH3O(CH2O)nCH3(wherein, n >=1, general value is less than 10, with DMMn
Represent).
α-polyoxymethylene weight is big, and course of dissolution viscosity is excessive, make general stirring do cannot normal work, the product of polymerization
Abnormal, viscosity is big when in the world existing synthesizer can not meet α-polyformaldehyde synthesis polymethoxy dimethyl ether, makes product point
Cloth is unreasonable, the bad control of N values.
Utility model content
The purpose of this utility model is to provide a kind of synthesizer of polymethoxy dimethyl ether, solves α-polyformaldehyde synthesis
Viscosity is big during polymethoxy dimethyl ether is distributed undesirable, the uncontrollable problem of N values.
The technical solution of the utility model is as follows：

Mouth, α-polyformaldehyde charging aperture one, bottom is provided with outlet；
Dissolving tank A sides are provided with the first polymer reactor, second polymer reactor of top mutually UNICOM, and the first polymerization is anti-
Answer device bottom inlet with dissolving tank A outlet at bottoms by being connected communicating pipe one, the first high-pressure pump is installed on communicating pipe one；
Second polymer reactor side is provided with dissolving tank B, and the second polymer reactor bottom is entered with dissolving tank B tops reactant liquor
Mouth is connected, and dissolving tank B tops are additionally provided with α-polyformaldehyde charging aperture two；
Dissolving tank B sides are provided with third polymerization reactor, the 4th polymer reactor that top is connected, third polymerization reaction
Device bottom, by being connected communicating pipe two, is provided with the second high-pressure pump with dissolving tank B bottoms on communicating pipe two；
4th polymer reactor bottom is provided with polymethoxy dimethyl ether discharge pipe.
Described polymethoxy dimethyl ether synthesizer, it is characterised in that described the first polymer reactor, the second polymerization
Catalyst is filled with reactor, third polymerization reactor, the 4th polymer reactor, catalyst adopts resin cation.
Described polymethoxy dimethyl ether synthesizer, it is characterised in that the second described polymer reactor bottom with it is molten
The first safety valve is respectively equipped with the top of solution tank B on the connecting pipe of reactant liquor import, the 4th polymer reactor bottom discharge pipeline
Door, the second safety valve.
The beneficial effects of the utility model are：
The utility model novel in structural design, can by α-polyformaldehyde synthesis polymethoxy dimethyl ether when, dimethoxym ethane and α-
Polyformaldehyde carries out mixing depolymerization through dissolving tank A, then coordinates the first polymer reactor, the second polymer reactor primary first-order equation, molten
Solution tank B hold it is secondary add secondary α-polyformaldehyde, Jing third polymerization reactors, the 4th polymer reactor secondary response again, effectively solving
α-polyformaldehyde adds that the big distribution of fashionable viscosity is undesirable, and the finished product N values of product are controllable.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
