The glycol fast determination dissociation calcium 
oxide analysis method and the instrumentation show
 Method abstract
   With the glycol - ethyl alcohol (2+1) solution,
under the temperature 100-110℃ , in the extract 
sample dissociation calcium oxide, can be complete in 2-3 minutes 
extracts, does not pass through the filtration, take the phenol tai
 as the indicator, with benzoic acid absolute ethyl alcohol standard 
solution direct titrate solution in glycol calcium.
•Method principle
The dissociation calcium oxide and the glycol in the
 absolute ethyl alcohol solution, in the temperature 100~110℃ function, 
responded the production glycol calcium, causes the phenol tai indicator to 
assume red, then to assumes red vanishing with the benzoic acid absolute 
ethyl alcohol standard solution titrate.
 
When according to titrate glycol calcium, the consumption 
benzoic acid absolute ethyl alcohol standard solution volume and to the calcium
 oxide titer, obtains the sample middle reaches to leave the calcium oxide
 the percentage.
•Reagent
1. glycol: The analytically pure (does not need to
dehydrate)
2. absolute ethyl alcohol: GR, the content is not
lower than 99.5%;
3. calcium carbonate: High pure reagent or datum
reagent;
4.0.1N sodium hydroxide absolute ethyl alcohol
solution: (2 grains the sodium hydroxide dissolves 
approximately) 0.2 gram in 50 milliliter anhydrous 
Yong Chun, is sure not the long time high temperature heating, 
the available flat
 head glass rod heats up while crushes.
5. glycol - ethyl alcohol (2+1) solution: 1000
milliliters glycol with 500 milliliter anhydrous
 mellow mixes, joins 0.06 grams phenol again tai, 
swings uniform, neutral assumes micro red with 
the 0.1N calcium hydroxide absolute ethyl alcohol 
solution, stores in the dry glass jar, presently 
uses presently to match, and has the moisture-proof 
measure
6.0.1N benzoic acid absolute ethyl alcohol standard
solution: Called 12.2 grams benzoic acid (in silica 
gel water extractor dry 24 hour later will dissolve 
beforehand) in the few absolute ethyl alcohol, then 
will shift to 1000 milliliters measuring flasks in,
 will flush with the absolute ethyl alcohol to the 
scale division, will swing uniform.
Demarcation method: The accurate name takes 0.04
grams calcium oxide (under the tempreture 950-1000℃ 
to fire 0.09 calcium carbonate to constant weight) 
puts in the dry 250 milliliter conical bottle, joins 
15~20 milliliter glycol - ethyl alcohol (2+1) solution,
 puts in a agitation, installs small prolongs, 
puts in on the dissociation calcium oxide cryoscope,
 opens the instrument power switch, after and treats 
pump normal work, the regulating instrument fixed 
time establishes the key (+10.+01) initializes to 4 minutes 
demonstrates (04), by the low rotational speed agitation solution,
 simultaneously elevates temperature the voltmeter adjustment in the 
150-220V position.
When under the condensation ethyl alcohol starts
trickles, presses starts the key, this time the number reveals the table right 
under second spot twinkle, the temperature decrease, the voltmeter instruction 
about 150V, increases the rotational speed slightly when hears the sound reports time
 the extract to finish, takes down the conical bottle, dissolves the bubble with the
 benzoic acid absolute ethyl alcohol standard to red vanishing, takes down the volume,
 heats up, boils, 4 minutes, the titrate, to red no longer appears up to, takes down
 the volume, closes the instrument total power switch.
Benzoic acid absolute ethyl alcohol standard solution
 to calcium oxide titer according to equation below 
idea:
In the formula: The TCaO- each milliliter benzoic
acid standard solution is equal to the calcium oxide 
milligram several (mg/ml)
      G- calcium oxide weight (g)
V- two titrate consumption benzoic acid standard
solution bulk volume (ml)

Analysis step
 The accurate name takes the test specimen 0.4 gram (to regard dissociation calcium oxide content to decide), puts in the dry 250 milliliter conical bottle, joins 15-20 milliliter glycol - ethyl alcohol solution, the jogging conical bottle causes the test specimen to disperse, puts in a agitation, installs small prolongs puts in on the dissociation calcium cryoscope, after opens the power switch to treat the circulating pump normal work, the adjustment operating time to 3 minutes, by the low rotational speed agitation solution, also elevates temperature, the voltmeter indicator adjusts about 150-180V in the position, when under the condensation ethyl alcohol starts trickles, presses starts the key, starts to time, falls the temperature voltmeter slightly to 150V about, increases the rotational speed slightlyafter Fixed time had ended, the extract finished, takes down the conical bottle, with the benzoic acid absolute ethyl alcohol standard solution titrate to red vanishing, takes down the volume, according to opens/stops the key, closes the instrument total power switch.
Percentage according to equation below computation:

The matters needing attention1.this method uses the reagent is anhydrous, the use finished should seal the preservation, the vessel should be dry.2.demarcation benzonitrile acid solution uses calcium oxide, when constant weight the laying aside time not suitable has grown in the water extractor, each time a name takes 1-2, when CaO absorption of moisture, demarcation the result is high.3.sample degree of fineness are smaller than was equal to the 0.08mm4.agitation heating time the control should carry on strictly according to the sequence.5.When titrates do not have to undulate intensely, when heating agitation the rotational speed cannot too be high.6.When determines above continuously three times, should be separated five minutes.7.Called the type quality may not fix invariably.8.When demarcation benzoic acid, after because pours into lightly the glycol and the ethyl alcohol cannot undulate intensely.
