Abstract
The invention relates to a manufacturing system of an antioxidant 168, comprising a reaction kettle, a crystallization kettle and a distilling kettle, wherein a vertical pressure filter is arranged between the reaction kettle and the crystallization kettle, a centrifugal machine is arranged between the crystallization kettle and the distilling kettle, and the connection sequence is: the reaction kettle, the vertical pressure filter, the crystallization kettle, the centrifugal machine, and the distilling kettle. The manufacturing system of the invention has the advantages of convenient operation, high product yield and purity, high utilizing rate of by-products, and short reaction time.
Description
Technical field
The present invention relates to a kind of production system, be specifically related to a kind of production system of oxidation inhibitor.
Background technology
Macromolecular material can receive effect such as heat, light, oxygen, heavy metal ion and mechanical shearing and take place aging in moulding, storage, use; Directly influencing Product Application is worth; Therefore add oxidation inhibitor usually; To suppress or to delay the oxidative degradation of polymkeric substance, prolong the work-ing life of macromolecular material.Oxidation inhibitor 168 belongs to organic phosphorous acid lipid oxidation inhibitor, and this kind antioxidant is a kind of auxiliary type oxidation inhibitor, through the superoxide in the decomposing copolymer oxidative degradation, reaches the purpose of the stabilization performance that improves polymkeric substance.The production system of oxidation inhibitor 168 is fairly simple at present, and the sub product that produces in its production process can not obtain good use and processing, and the utilization ratio of product is lower.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of easy to operate in order to overcome deficiency of the prior art, and product yield and purity are high, and the by-product utilization rate is high, the production system of the oxidation inhibitor 168 that the reaction times is short.
Technical scheme: in order to solve the problems of the technologies described above; The production system of oxidation inhibitor 168 of the present invention; It comprises reaction kettle, crystallization kettle and still kettle; Between said reaction kettle and crystallization kettle, be provided with vertical type blotter press, between said crystallization kettle and still kettle, be provided with separating centrifuge, the order of connection is reaction kettle, vertical type blotter press, crystallization kettle, separating centrifuge and still kettle.
Said separating centrifuge links to each other with the fluidized drying machine.
Said still kettle links to each other with condensing surface.
Said reaction kettle is with 2, and 4-DI-tert-butylphenol compounds and phosphorus trichloride are that raw material reacts under conditions such as solvent, catalyzer, generates desired product; Crystallization kettle plays evaporating solns, and the impurity in the cleaning products is guaranteed product yield and purity; Still kettle be with employed solvent in the reaction process through the distillation recycling, the charging of reaction kettle is to lean on negative pressure of vacuum to suck and the header tank dropping, and is easy to operate; Be easy to pressure control and temperature control, two-level absorption tower is adopted in the absorption of sub product hydrogenchloride, through the steam jet vacuum pump machine; Can in time extract the hydrogenchloride that generates out reaction kettle, both guarantee carrying out fully of reaction, the concentration of hydrochloric acid that reclaims simultaneously is more than 32%; Improved utility value, fluid bed dryer adopts high pressure draft multistage gas to turn over eliminating water vapour, can the product water cut be reduced to below 0.2%; Reaction soln through vertical type blotter press, has improved product gas purity when changeing still.
Beneficial effect: the present invention compared with prior art; Its remarkable advantage is: one-piece construction of the present invention is simple; Adopt vertical type blotter press and crystallization kettle to improve product gas purity, the employing two-level absorption tower has improved the utilization ratio of sub product, and is simple to operate between each reaction kettle; Reduce labour intensity, improved working efficiency.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1; The production system of a kind of oxidation inhibitor 168 of the present invention; It comprises reaction kettle 1, crystallization kettle 2 and still kettle 3; Between said reaction kettle 1 and crystallization kettle 2, be provided with vertical type blotter press 4, between said crystallization kettle 2 and still kettle 3, be provided with separating centrifuge 5, the order of connection is reaction kettle 1, vertical type blotter press 4, crystallization kettle 2, separating centrifuge 5 and still kettle 3; Said separating centrifuge 5 links to each other with fluidized drying machine 6; Said still kettle 3 links to each other with condensing surface 7.One-piece construction of the present invention is simple, adopts vertical type blotter press and crystallization kettle to improve product gas purity, and the employing two-level absorption tower has improved the utilization ratio of sub product, and is simple to operate between each reaction kettle, reduced labour intensity, improved working efficiency.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
