Description
Technical field
The invention belongs to fine chemistry industry to analyze testing field, more particularly to a kind of to derive Production by Catalytic Combustion Process measure based on TOC
The method of hydroxylamine salt organic residue.
Background technology
Hydroxylamine salt is widely used chemical products.HAS and phosphatic hydroxylamine are mainly with producing caprolactam, agriculture
Medicine etc.；Hydroxylamine hydrochloride is mainly used as the raw material of the compound probabilities such as medicine, spices, dyestuff.The production process of hydroxylamine salt mainly includes
Synthesize, concentrate, filtering, crystallizing the link such as (or recrystallization), dry.Hydroxylamine salt is melted into most organic solvents, thus product
Middle generally existing organic residue.The composition of organic residue is probably that the one or more in raw material, solvent, recrystallization liquid are mixed with
Machine thing.Hydroxylamine salt release acid, can influence product quality with oximation reaction occurs containing carbon-based compound.By taking hydroxylamine hydrochloride as an example,
In pharmaceutical intermediates such as synthesizing hydroxyamine-O- sulfonic acid, the hydrochloride of carboxylic formic acid azanol half, salicylaldehyde derivatives, hydroxysuccinimides
When, if too high organic residue be present, downstream quality is had and had a strong impact on.
There are HG/T 3736-2013 disclosed in the execution specification country of hydroxylamine salt at present《Technical hydrochloric acid azanol》、GB/
T6685-2007《Chemical reagent hydroxylamine chloride》、HG 3-968-76《Chemical reagent HAS》、HGB3201-1960《Sulfuric acid
Azanol》These four standards.The inside has related generally to azanol salt content, moisture, ignition residue, sulfate, ammonium, iron, arsenic, a huge sum of money
Belong to the analysis method of these indexs.Without reference to the detection of organic residue in hydroxylamine salt.The hydroxylamine salt analysis skill that subsequent research goes out
Art, such as《Indirect spectrophotometric methods determine hydroxylamine hydrochloride》、《Murexide-iron spectrophotometer method measure hydroxylamine hydrochloride》It is to utilize hydroxyl
The reproducibility or hydroxylamine salt of amine salt and the chemical reaction of reagent are analyzed content.Patent of invention《Hydrazine nitrate, HAN
Assay method》Disclose it is a kind of using infrared light in specific wavelength and special time lower integral, reference is done to nitre with water or air
Sour hydrazine, HAN are measured.Document《One kind determines cyclohexanone oxime and HAS in cyclohexanone oxime hydrolysis simultaneously and contained
The method of amount》It is referred to and uses high performance liquid chromatography and oxidimetry, deducts the height of theoretical cyclohexanone oxime consumption
The amount difference of potassium manganate obtains the content of HAS, and this method has certain limitation, and the too low error of concentration is big, to not ultraviolet
The organic matter of absorption is invalid.And it is only applicable to cyclohexanone oxime.Patent《A kind of meteorological derivative chromatography quickly determines hydroxylamine hydrochloride
Content》Primarily directed to the residual of raw material hydroxylamine hydrochloride in Risperidone and its intermediate.
Therefore, the analysis method of hydroxylamine salt has a titration at present, indirect spectrophotometric methods, based on redox principle,
For the main content of hydroxylamine salt, for hydroxylamine salt organic residue also without analysis method for reference.
The content of the invention
The present invention is directed to the defects of above-mentioned, proposes that one kind derives Production by Catalytic Combustion Process based on TOC and determines hydroxylamine salt organic residue
Method, can accurately analyze the organic residue of hydroxylamine salt, calculate specific content of organics, prevent that hydroxylamine salt is too high because of organic residue
And quality is influenceed, make the analysis of hydroxylamine salt become perfect, contribute to product quality to be lifted.
For this, the present invention adopts the following technical scheme that, one kind is organic residual based on TOC derivative Production by Catalytic Combustion Process measure hydroxylamine salts
The method stayed, it is characterised in that after being handled using characteristic reagent sample, recycle particular instrument method, detect organic residual
Content is stayed, by subtracting the Residual organic solvent of derivative reagent, the final content for calculating determinand organic residue.It is specific use with
What lower technical scheme was realized：
Firstth, instrument condition, TOC analyzers.
Sample determines：Solid sample is made into the solution of 0.5~4 grams per milliliter with high purity water, fluid sample then takes 1~2
Gram, 10ML characteristic reagents are added, after progress fully shaking shakes up, it is to be measured that high purity water is diluted to 50~100 milliliters of placement volumetric flasks.
Using TOC analyzers, 1~3 appropriate standard curve, analysis are selected.Result is obtained to be computed drawing specific organic substance residues
Amount.ML=TOC × r × 100%.In formula：ML is specific organic substance residues percentage amounts, and %, r are TOC and organic matter molal weight
With carbon containing molal weight ratio；Described testing sample can be the solid, liquid hydroxyl amines salt, oxime hydrochloride that oxime hydrolyzes to obtain.
Oxime therein includes, acetaldoxime, acetoxime, diacetylmonoxime, cyclohexanone oxime, benzaldoxime, methyl isobutyl ketoxime, methyl propyl ketone

Directrix curve is prepared quantitatively to lead potassium hydrogen phthalate or quantifying organic matter to be measured.Described IC curves are quantitative sodium acid carbonate and carbon
Sour sodium is prepared.Described standard curve includes IC standard curves and TC standard curves；Standard curve Cmin is more than or equal to 0 milli
G/l, Cmax be less than or equal to 4000 mg/litres；Can simultaneous selection be less than or equal to the curve in 3 different sections.Including 0
~200 mg/litres, 0~500 mg/litre, 0~1000 mg/litre, 0~2000,0~4000 mg/litre isoconcentration scopes
One or less than or equal to three curves.Described characteristic reagent be acetone, butanone, ethanol, methanol it is therein any one, feature
The concentration of reagent is 5000mg/L.
3rd, controlled analysis：After taking 10ml characteristic reagent, progress fully shaking to shake up, 50 are settled to high purity water
~100 milliliters of volumetric flasks are to be measured.Using TOC analyzers, 1~3 appropriate standard curve, analysis are selected.Result is obtained through meter
Calculation draws control group Residual organic solvent.
The present invention be directed to the solid, liquid hydroxyl amines salt, oxime hydrochloride that oxime hydrolyzes to obtain, and first carries out sample to derive place
Reason, TOC analyzers are recycled, detect organic residue content, by subtracting the Residual organic solvent of derivative reagent, finally calculate to be measured
The content of thing organic residue.The perfect attributional analysis of hydroxylamine salt, prevents the too high influence quality of organic residue.
Compared with existing analytical technology, the present invention has following remarkable advantage：
