Description
Technical field
The utility model relates to a kind of dewater unit of salicylic acid intermediate sodium phenate, belongs to sodium phenate dehydration technique field.
Background technology
Salicylic purposes is quite extensive, is current extremely important medicine chemical material, mainly for the manufacture of antipyretic, analgesic aspirin, is also the raw material that the multiple important drugs such as gaultherolin, salethyl and salicylamide produces synthesis simultaneously.Only salicylic domestic market scale is at about 20,000 tons, China is salicylic acid spin-off producing country and the exported country such as aspirin, gaultherolin main in the world, therefore salicylic use amount is huge, and therefore short, simple to operate, eco-friendly technique is very necessary the development technology time.
The traditional synthesis technique of salicylic acid produces sodium phenate with phenol or phenol solution with NaOH reaction, the frequent press-dehydrating of aqueous sodium phenolate solution, decompression dehydration, dry with phenol band water again, then carry out carboxylation reaction with carbon dioxide at about 200 DEG C and produce sodium salicylate, add water and generate sodium salicylate solution.Salicylic acid product is bulk raw material product, because normal pressure dewatering time is long, to consume quantity of steam huge, heat utilization efficiency is low.For shortening the process time and improving efficiency of utilization, need to research and develop new dewater unit.
Utility model content
The purpose of this utility model is to provide a kind of dewater unit of salicylic acid intermediate sodium phenate, and its simplicity of design is scientific and reasonable, shortens the process time, improves efficiency of utilization.
The dewater unit of described salicylic acid intermediate sodium phenate, comprise sodium phenate preparing tank, kestner long-tube evaporator, condenser, concentrated sodium phenate collector and condensate recovering device, the bottom of sodium phenate preparing tank is connected with the charging aperture at kestner long-tube evaporator top, and the gas outlet at kestner long-tube evaporator top is connected with condensate recovering device successively with condenser; Discharging opening bottom kestner long-tube evaporator is connected with concentrated sodium phenate collector; Kestner long-tube evaporator, condensate recovering device and concentrated sodium phenate collector are equipped with vavuum pump; The pipeline that sodium phenate preparing tank is connected with kestner long-tube evaporator is provided with control valve and spinner flowmeter.
Described concentrated sodium phenate collector is connected with electronic scale.
Described sodium phenate preparing tank top is provided with feed pipe.
The outside of described sodium phenate preparing tank, kestner long-tube evaporator and concentrated sodium phenate collector is equipped with chuck, chuck is equipped with import and outlet.
The utility model has following beneficial effect:
The utility model simplicity of design, scientific and reasonable, operating environment is greatly improved, shorten about 2 hours process times, improve efficiency of utilization, the use amount of steam decreases 1/3, only this saving more than 200 ten thousand yuan every year of steam, has good economic benefit and social benefit.
