Description
Technical field
The utility model belongs to the synthesis technical field of thermoplastics stablizer, is specifically related to a kind of diphenylpropane-1,3-dione(DPPO) preparation system efficiently.
Background technology
Diphenylpropane-1,3-dione(DPPO) belongs to beta-diketon class organic compound, it is a kind of nontoxic, efficient, environment-friendly type macromolecule auxiliary heat stabilizer, good with calcium/zinc heat stabilizer synergy, alternative traditional lead, cadmium thermo-stabilizer, represent the developing direction of thermo-stabilizer, be common to the processing of plastics (PP, PE, ABS, PS, PVC etc.).In diphenylpropane-1,3-dione(DPPO) building-up process, methyl benzoate and methyl phenyl ketone reaction is adopted to be a kind of important methods, as Chinese patent " a kind of preparation method of diphenylpropane-1,3-dione(DPPO) " (201310437534.6) discloses a kind of preparation method of diphenylpropane-1,3-dione(DPPO), it utilizes sodium hydride to reduce temperature of reaction as catalyzer, but the synthesis of diphenylpropane-1,3-dione(DPPO) is thermopositive reaction, the rate of addition controlling a certain raw material is utilized to control temperature of reaction system in prior art, the temperature of reaction system is made to be unlikely to too high, but and hence, limit rate of addition, have impact on the production efficiency of diphenylpropane-1,3-dione(DPPO).
Utility model content
The purpose of this utility model is to provide a kind of efficient diphenylpropane-1,3-dione(DPPO) production equipment simple to operate.
For achieving the above object, the technical solution adopted in the utility model is, a kind of diphenylpropane-1,3-dione(DPPO) preparation system efficiently, comprise reactor, methyl benzoate storage tank, sour storage tank, feed pot and cooling tank, the bottom of reactor is serially connected with strainer, the first separating funnel, caustic treater, the second separating funnel, water washing tank, the 3rd separating funnel and water distilling apparatus successively; Reactor is arranged in cooling tank, and the bottom of cooling tank side is connected with water inlet pipe, and cooling tank opposite side top is connected with rising pipe; Methyl benzoate storage tank, sour storage tank, feed pot are connected with the top of reactor respectively by valve.
In described reactor, whipping appts is installed.
The beneficial effect that the utility model produces is cooled reactor by cooling tank, can accelerate the rate of addition of methyl phenyl ketone, improves the combined coefficient of diphenylpropane-1,3-dione(DPPO) from face.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, but protection domain of the present utility model is not limited thereto.
As shown in Figure 1, a kind of diphenylpropane-1,3-dione(DPPO) preparation system efficiently, comprise reactor 1, methyl benzoate storage tank 12, sour storage tank 14, feed pot 15 and cooling tank 9, the bottom of reactor 1 is serially connected with strainer 2, first separating funnel 3, caustic treater 4, second separating funnel 5, water washing tank 6, the 3rd separating funnel 7 and distiller 8 successively; Reactor 1 is arranged in cooling tank 9, and the bottom of cooling tank 9 side is connected with water inlet pipe 11, and cooling tank opposite side top is connected with rising pipe 13; Methyl benzoate storage tank 12, sour storage tank 14, feed pot 15 are connected respectively by the top of valve with reactor 1.Agitator 10 is installed in reactor 1.
During use, methyl benzoate in methyl benzoate storage tank 12 joins in reactor 1 by valve, methyl phenyl ketone, sodium hydride, dimethylbenzene, other raw material such as gac joins in reactor 1 by feed pot 15, water coolant enters in cooling tank 9 through water inlet pipe 11 and carries out heat exchange with reactor 1, after heat exchange, water is discharged from rising pipe 13, after reactor 1 Raw reacts completely, the hydrochloric acid being added 30% by sour storage tank 14 in reactor 1 carries out acidifying, and constantly stir, after acidifying completes, the Liquid transfer in reactor is filtered in strainer 2, the liquid obtained after filtration is sent in the first separating funnel 3 and carries out separatory, be sent to being separated the organic phase obtained in the first separating funnel 3 in caustic treater 4, the sodium carbonate solution adding 6%wt carries out alkali cleaning, alkali cleaning in caustic treater 4 is obtained to liquid to be sent in the second separating funnel 5 and to carry out separatory, the organic phase that separatory in second separating funnel 5 obtains is sent in water washing tank 6, adds water and wash, the liquid obtained after washing in water washing tank 6 is sent in the 3rd separating funnel 7 and carries out separatory, be separated the organic phase feeding distiller 8 obtained in the 3rd separating funnel 7 and distill, can diphenylpropane-1,3-dione(DPPO) be isolated.
