Abstract
The invention provides a regeneration method of an aged naphthenic acid organic phase. Gamma-aluminum oxide serves as a regeneration agent. The aged naphthenic acid organic phase is transferred into a reaction kettle, and 30 g-40 g of the gamma-aluminum oxide is added to a liter of the aged naphthenic acid organic phase; stir treatment is conducted for 16 h-18 h at the room temperature, then filtration is conducted, filtrate serves as the regenerated naphthenic acid organic phase, and the yield ranges from 95 percent to 97 percent. The regeneration method of the aged naphthenic acid organic phase has the advantages of being short in technological process, high in regeneration speed, less in chemical reagent dosage, free of waste liquor discharge, simple in equipment, easy and convenient to operate, low in regeneration cost and the like.
Description
Technical field
The present invention relates to a kind of renovation process of aging aphthenic acids organic faciess, more particularly to one kind with gama-alumina is
Regenerative agent, the method for recovering aging aphthenic acids organic extractant phase performance and function.The present invention particularly belongs to solvent extraction technology neck
Domain.
Background technology
Aphthenic acids are that one kind is mainly used in from high yttrium element ore deposit（Such as, Long Nankuang）Middle separation prepares fluorescence-class yttrium oxide
Acidic extractant.In actual use, generally aphthenic acids are dissolved in kerosene or sulfonated kerosene and are added a certain amount of has
Machine alcohol（Such as mixed alcohol, sec-octyl alcohol etc.）Organic faciess are made for demulsifier.Make as aphthenic acids organic faciess are circulated for a long time
With, thus aphthenic acids organic faciess inevitably gradually occur esterification, oxidation etc. reaction and change and there are catabiosis.Although
It was found that the existing many decades of aphthenic acids organic media aging phenomenon, but the agine mechaism of aphthenic acids organic faciess there is no final conclusion so far.
But, from organic faciess in appearance, the ageing process of aphthenic acids organic faciess be a transparency by clear feculence, color by shallow change
The deep change procedure up to caramel.Aphthenic acids organic faciess after aging, load capacity is decreased obviously, separation efficiency significantly drops for extraction
Low, the split-phase time significantly extends, serious emulsification not even split-phase.
Due to aphthenic acids organic media aging speed it is fast, it is long then 2 years, it is short, will use within 1 year.Therefore, this area is not
Few professional and technical personnel has attempted various chemical reagent and technological means carries out Regeneration Treatment to aging aphthenic acids organic faciess, but
As a result it is undesirable, fail to obtain the technological achievement with practical value.Due to there is no successful renovation process, when aging cycloalkanes
When sour organic faciess cannot be used, current Disposal Measures are typically discarded.Aging aphthenic acids organic faciess are discarded, not only economically
Certain loss, and serious environment pollution can be suffered, affects ecological.
The content of the invention
The purpose of the present invention is the method for there is no rejuvenating aged aphthenic acids organic faciess, overcomes discarded aging aphthenic acids to have
Machine mutually pollutes environment, affects ecological problem, sets up a kind of easy, fast and efficiently rejuvenating aged aphthenic acids organic faciess side
Method.
A kind of renovation process of aging aphthenic acids organic faciess of the present invention, with gama-alumina as regenerative agent.By aging aphthenic acids
Organic faciess are transferred in reaction pot, and the organic 30 g～40 g particle diameters that are added to of per liter of aging aphthenic acids are 4 mm～6 mm, BET ratios
Surface area is 220 m2/ g～240 m2The gama-alumina of/g, is filtered after 16 h～18 h of stir process under room temperature, filtrate
To regenerate aphthenic acids organic faciess, its yield is 95%～97%.
It is an advantage of the invention that：Technological process is short, and reproduction speed is fast, and chemical reagent consumption is few, without discharging of waste liquid, equipment letter
Single, easy to operate, regeneration cost is low.
