Abstract
The utility model discloses a multi-tower continuous operation system device for synthesizing methyl 3,3-dimethyl pentenoate, relating to chemical equipment. A plurality of reaction kettle towers of the equipment are connected in series; a plurality of rectifying towers are connected in parallel; a blending tank is connected with the reaction kettle tower a and the reaction kettle tower b through a pipeline and a crushing pump; a methanol recycling tank and a trimethyl orthoacetate recycling tank are respectively arranged below the reaction kettle tower a and the reaction kettle tower b; a trimethyl orthoacetate recycling tank and a finished product tank are respectively arranged below each rectifying tower; and the trimethyl orthoacetate recycling tanks are connected with the blending tank through recycling pipelines. Multi-tower connection is adopted in the utility model, thus, continuous operation is realized, and defects of continuous temperature rise and reduction of the original device are overcome. The device has the advantages of high utilization ratio, stability in operation and capability of reducing carbides and side reaction, shortening reaction time and increasing the yield.
Description
Technical field
The utility model relates to a kind of chemical plant.
Background technology
The synthetic of 3,3-dimethyl-4-pentenoic acid methyl ester all is that single tower separates at present, and single tower distillation must obtain finished product after intermittent type separation of methanol, trimethyl orthoacetate and the rectifying through the cooling that constantly heats up.Aforesaid device can not be realized continuous operation, utilizes rate variance, fluctuation of service, spinoff many, and reaction time is long, and yield is low and carbide is many.
Summary of the invention
The purpose of the utility model provides the synthetic multitower serialization os equipment of a kind of 3,3-dimethyl-4-pentenoic acid methyl ester; Separate to solve the single tower of prior art; Single tower distillation can not be realized continuous operation, utilizes rate variance, fluctuation of service, spinoff many; Reaction time is long, and yield hangs down the problems such as carbide is many that reach.
The utility model mainly is made up of reaction kettle, rectifying tower and material stock jar; Solving the technical scheme that its technical problem adopts is a plurality of reaction kettle towers series connection; A plurality of rectifying tower parallel connections; Mixing tank is through pipeline, dnockout pump ligation still a tower, and reaction kettle a tower, reaction kettle b tower below are provided with Methanol Recovery jar and trimethyl orthoacetate withdrawing can respectively, and each rectifying tower below is provided with trimethyl orthoacetate withdrawing can and finished product jar respectively; The trimethyl orthoacetate withdrawing can connects mixing tank through recovery channel.
Adopting the utility model positively effect is multitower to be set connect, and has realized continuous operation, has overcome the continuous intensification cooling of original equipment.Usage ratio of equipment is high, and stable operation has reduced carbide and side reaction, has shortened the reaction times, has improved yield.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the utility model structural representation;
1 pipeline, 2 reaction kettle a towers, 3 reaction kettle b towers, 4 rectifying a towers, 5 rectifying b towers, 6 finished product jars, 7 trimethyl orthoacetate withdrawing cans, 8 Methanol Recovery jars, 9 recovery channels, 10 dnockout pumps, 11 mixing tanks among the figure.
Embodiment
As shown in the figure: two reaction kettle tower 2,3 series connection; Two rectifying tower 4,5 parallel connections; Mixing tank 11 is through pipeline 1, dnockout pump 10 ligation still a towers 2; Methanol Recovery jar 8 is set respectively for reaction kettle a tower 2, reaction kettle b tower 3 belows and 7, two rectifying tower of trimethyl orthoacetate withdrawing can, 4,5 belows are provided with trimethyl orthoacetate withdrawing can 7 and finished product jar 6 respectively; Trimethyl orthoacetate withdrawing can 7 connects mixing tank 11 through recovery channel 9.
