Background technology
(near-critical water NCW), is meant the compressed liquid water of temperature between 200 ℃～350 ℃ to near-critical water.Good owing to mass-transfer performance, as self to have the function of acid catalysis and base catalysis and have energy while dissolved organic matter and inorganics characteristic, therefore its organic solvent that can substitute murder by poisoning carries out chemical reaction, even remove the adding of acid base catalysator from, make organic chemical reactions in NCW, the detachment process among the NCW, the renewable resources technology among the NCW etc. become one of focus in recent years.And, a natural abundance high important directions becoming Green Chemistry chemical industry development nontoxic, cheap with it.
Material solubleness in NCW is green chemical process necessary base data among the research and development NCW, have only reactant, intermediate and the final product dissolving situation in NCW that fullys understand a chemical reaction process, could grasp, control the carrying out of this course of reaction.But because the chemical process applied basic research also is in state at the early-stage among the NCW, the High Temperature High Pressure operating difficulties is very high to equipment requirements in addition, and basic data relevant among the NCW is lacked very much, has hindered the research and the application process of green chemical process among the NCW.
The solubility test method has three kinds of cloud point method, dynamic method and static methods etc. among the NCW.Because the cloud point method is to the equipment requirements height, dynamic method cannot say for sure that card reaches balance, so static method is the High Temperature High Pressure method commonly used in the research that balances each other.When static method is measured among the NCW solubleness, how to keep temperature, pressure condition in the equilibrium still constant, how under high pressure the sample in the equilibrium still to be taken out, and the sample that takes out is representative, and not change in sampling process be the gordian technique of measuring and form.At present, also there is not ripe perfect proving installation that solubleness among the NCW is carried out system measurement both at home and abroad.
Summary of the invention
The purpose of this utility model provides solubility test device in a kind of near-critical water.
It has sampling system successively, pressure compensating system, equilibrium still, temperature control system and sampling system, sampling system has high-pressure metering pump successively, first valve, second valve, the nitrogen steel cylinder, pressure compensating system has the 3rd valve successively, the 4th valve, surge tank, the 5th valve, tensimeter, equilibrium still has kettle, stirrer, safety valve, tensimeter, atmospheric valve, tapping valve, temperature control system has muff successively, temperature controller, on sampling system has, in, following three level sampling pipeline, the upper strata pipeline has first sample valve successively, second sample valve, quantity tube, the 3rd sample valve, relief tube, middle tube has the 4th sample valve successively, the 5th sample valve, quantity tube, the 6th sample valve, relief tube, lower floor's pipeline has the 7th sample valve successively, the 8th sample valve, quantity tube, the 9th sample valve, relief tube.Join with the 6th valve between pressure compensating system and equilibrium still.
Advantage of the present utility model: can be quick, accurately the organism among the NCW/inorganics solubleness is carried out system measurement, adopt surge tank to carry out ftercompction, sampling process pressure changes little; Adopt the sampling of semi-fluid dynamic formula quantity tube, can guarantee the representativeness of sample; Adopt PID to regulate temperature-controlled precision height (± 1 ℃); Kettle adopts titanium alloy TC 4, and is corrosion-resistant; The versatility of device is good, except measuring the solubleness in the near-critical water, also can be used for stability study, reaction kinetics research in the near-critical water.
