Analysis of gas phase color atlas produces medium application in ester of carbon
From;    Author:Stand originally

1 preface
The production of ester of carbonic acid propylene is with annulus oxygen propane and carbon dioxide are raw material, below activator action, synthesize fluid of ester of propylene of thick carbonic acid at constant temperature and pressure are being controlled inside reactor, distill of vacuum of classics of fluid of ester of propylene of thick carbonic acid gets purity is more than 99.5 % product. Lead the part of fluid of ester of propylene of need monitoring thick carbonic acid to make sure annulus oxygen propane is changed, adjust reaction requirement in time according to the content of annulus oxygen propane, adjust rectification to operate according to finished product quality. According to stock character we decide to the analysis accuses in choosing gas phase color atlas to undertake. There is propane of oxygen of ester of carbonic acid propylene, water, annulus, third in synthesizing fluid the constituent such as 2 alcohol, activator, bromic ethane, 3 ethylamine, among them bromic ethane, 3 ethylamine are activator disclose result, need to depart each constituent, detached effect is poorer when because constituent is more,using color atlas of constant temperature gas phase to analyse. We use a program to warm up via the experiment law, actor chooses an experiment to operate a condition, can depart constituent, mensurable in satisfying, accuse to detect with finished product requirement, test result accuracy is taller.
2 experiments
2. 1 instrument and reagent
Instrument: North divides appearance of color atlas of SP-3420 gas phase and color atlas workstation, electronic balance (accurate 0.0001g) , packed column of stainless steel of φ 3mm X 2m, injector of minim of 5 μ L.
Reagent: Propane of oxygen of 2 alcohol, annulus, bromic ethane, 3 ethylamine all are ester of carbonic acid propylene, third the analysis is simple; Hydric, 99.9 % of purity ≥ .
2. 2 experiments method
2. 2. What F of corrective to quality factor is worth 1 photograph is affirmatory
Accurate on analytic balance metage is certain of quality each are fiducial reagent (deserve accurately to be tasted into composite sample to 0.0001g) , take shape with minim implement absorb this composite sample L of 1 μ , appearance of color atlas of infuse gas phase undertakes an analysis, it is standard content with ester of carbonic acid propylene, via color atlas workstation processing gets the peak area of each material, computation gives the relatively corrective factor of each material.
2. 2. 2 experiments measure
Use normalization law to undertake each constituent ration determines, take shape with minim implement absorb wait for survey sample in appearance of color atlas of gas phase of infuse of 1 μ L, chromatogram gets below condition of operation of make choice of, via processing of color atlas workstation, reach propane of oxygen of the ester of carbonic acid propylene in sample solution, annulus, bromic ethane, third the content of the constituent such as 2 alcohol, 3 ethylamine, water.
