Description
Technical field
The invention belongs to chemical technology field, specifically refers to a kind of devices and methods therefor of sodium formate synthesis.
Background technology
Sodium formate, chemical formula HCOONa 2H2O, slightly formic acid smell.Soluble in water and glycerine, is slightly soluble in ethanol.253 DEG C of fusing point（Anhydride）, poisonous.Hydrogen and sodium oxalate is decomposed into during heat-flash.As leather industry, camouflage acid in chromium tanning, for catalyst and stablize synthetics, the reducing agent of dyeing, for producing sodium hydrosulfite, oxalic acid and formic acid.It is white or pale yellow crystals solid, slightly hygroscopy under normal temperature.Micro- have formic acid smell.There is hygroscopicity.Sodium oxalate and hydrogen is resolved into during high temperature, then generates sodium carbonate.It is dissolved in about 1.3 parts of water.Glycerine is dissolved in, ethanol, octanol is slightly soluble in, insoluble in ether.Its aqueous solution is in alkalescence.Relative density 1.92.253 DEG C of fusing point.Irritant.Commodity often contain 2 molecular crystalline water.As leather industry, camouflage acid in chromium tanning, for catalyst and stablize synthetics, the reducing agent of dyeing, for producing sodium hydrosulfite, oxalic acid and formic acid.Precipitate precious metals.The complex ion of trivalent metal can be formed in the solution.There is cushioning effect, the pH value of strong acid can be corrected.For phthalic resin coating, plasticizer, high explosives, acid resisting material, aeroengine oil, adhesive additive.
Sodium formate mainly has following production method：
Carbon monoxide synthetic method, preparation method：The reaction under 160 ~ 200 DEG C and 2MPa pressure of carbon monoxide and sodium hydroxide solution generates sodium formate, then gets product formic acid through sulfuric acid solution, distillation.Brief description of the process is as follows：This engineering is raw material using coke, through gas making dedusting, washing, again decarburization, the technique such as dedusting, the CO gas needed for technique are obtained, then heated pressurization is reacted with NaOH and sodium formate solution is generated, by evaporation, separate, dry generation solid product sodium formate.Being described as follows of each post：1st, coke electric block is promoted to Gas-making Furnace top, adds coke to stove from Gas-making Furnace fire door, coke is drawn with blower fan in stove（Send）The air burn incompletely for entering produces the mixed gas such as carbon monoxide, carbon dioxide, nitrogen.2nd, from Gas-making Furnace come mixed gas enter cyclone dust collectors go out mixed gas entrainment most of solid granule, aeration tower is entered afterwards, aeration tower is with water as cleaning solution, solid particle in mixed gas is removed further, caustic wash tower is entered back into sodium hydroxide solution as circulating absorption solution, partial CO 2 gas in removing mixed gas, the moisture for gas entrainment being separated through cyclone hydraulic separators again enters electrostatic precipitator, remaining solid granule is removed by electrostatic, purifies mixed gas again.3rd, the mixed gas after purifying enter compressor and carry out two sections of compressions, pressure-raising is to 2.0 ~ 2.2Mpa, blender is entered through oil water separator, mix with the alkali lye come from preheater, under uniform temperature and pressure, alkali lye and most of carbon dioxide gas precursor reactant, eliminate substantially carbon dioxide, obtain the CO gas needed for technique.4th, the CO gas for coming from a upper operation and nitrogen are heated to 140 ~ 150 degree of entrance synthesis reactor, in synthesis reactor, carbon monoxide generates sodium formate solution with NaOH reaction, sodium formate solution and the mixture such as nitrogen and micro CO gas carry out gas-liquid separation through entering cyclone hydraulic separators after release, sodium formate solution pump squeezes into that storage tank is stand-by, and mixed gas enter air.5th, the sodium formate solution in storage tank is with being pumped into evaporimeter, with oil oven come heat-conducting oil heating, evaporate most of moisture, form 70 ~ 80% sodium formate solution of content, afterwards with being pumped into centrifuge, centrifuge is dry obtain 5% or so sodium formate.6th, the sodium formate solution hot blast after being centrifuged blows to hot-air drier drying, obtains qualified sodium formate product, is packed.
Now, also there is a kind of method i.e. using ethanol as solvent, at normal temperatures and pressures sodium formate can be prepared by the carbonylation of carbon monoxide and NaOH, but, reaction speed is slower, and product yield is not high.And without supporting production equipment, it is impossible to it is applied to industrial production.
