Description
Technical field
The utility model belongs to the field of chemical synthesis, particularly discloses a kind of HTHP hydrothermal reactor of easy operating.It is a kind of device that is used for chemical synthesis.Wherein term " hydro-thermal " means chemical synthesis and in liquid phase, carries out, and synthesis temperature is equal to or higher than the boiling temperature of reaction dissolvent, and synthesis pressure is equal to or higher than ambient atmosphere pressure.Reaction dissolvent can be a water, also can be other nonaqueous solvents.
Background technology
The hydrothermal chemistry synthetic method can be used to synthetic many organic and inorganic compounds.Its advantage is following: ability is the good anhydrous crystalline phase of synthetic crystallization directly, can control grain size and distribution effectively, can simplify building-up process.When the high supercriticality to reaction dissolvent of reaction temperature and pressure, hydro-thermal reaction can also be made the novel substance structure that under atmospheric pressure state, is difficult for making.
Traditional hydrothermal reactor is a closed container of being made by steel.Reaction medium comprises that reactive material and water or nonaqueous solvents thereof all are contained in the container.The heater that is located at external container is to the heating of container wall, the reaction medium that the container wall of heat and then heating container are interior; Reaction solution receives thermal evaporation, in container, produces thermal balance pressure.Reaction temperature is high more, and the thermal balance pressure that is produced is big more.
Because the traditional water thermal reactor bears high temperature and high pressure simultaneously, there are some technical problems in it.It at first is reactor anti-high pressure ability at high temperature.On the one hand, the thermal balance pressure that is produced by reaction dissolvent evaporation is along with the rising of reaction solution temperature is sharply risen; On the other hand, the mechanical strength that is used to make the steel of reaction vessel then raises with temperature and causes the reduction that can not be ignored.With the aqueous solution is example, and when the temperature of reaction solution reached 400 ℃, the thermal balance pressure that is produced by the solution evaporation surpassed 400 atmospheric pressure.If according to this is modal method, the steel that are used to make reaction vessel are 316 stainless steels, and container will be reduced to 67% of at normal temperatures ability 400 ℃ compressive resistance ability.In order to make reactor require safe handling under the HTHP, the most frequently used method is the thickness that increases wall of reactor.Do to such an extent that the result makes that reactor volume is heavy, cost is high like this, the heat transfer efficiency of wall is low.
Second problem of traditional water thermal reactor is wiper seal.The common method of sealing is to be clipped in encapsulant between the flange and container cover that is welded on the container cartridge, is pressed against each other flange and container cover with a series of fastening bolts, makes the distortion of encapsulant appropriateness.Because it is hot that the housing of reactor is in, the rubber packing material of excellent spring can not be used, and can only use the composite of metal or graphite and other high-temperature resistance plastices.These suitable fixedly prestressing force of material require that are applicable to delivered pressure sealing under the hot conditions just can work.For example, the fixedly prestressing force of flexible carbonaceous encapsulant is 17 MPas, and the fixedly prestressing force of wire-graphite composite seal reaches 68 MPas.So high fixedly prestressing force makes the very inconvenience of closure and open operation of reactor.
The 3rd problem of traditional water thermal reactor is chemical attack.Metal material is not corrosion-resistant well-known.Though 316 stainless steel resist chemical performances are better than other steel, it is especially at high temperature all the more so far away from glass and pottery.The chemical attack problem of reactor not only reduce reactor the compressive resistance ability, shorten reactor service life, also cause pollution to chemical synthesis.In order to solve the chemical attack problem, a kind of way is at reactor wall lining fluoride plastics, like polytetrafluoroethylene (PTFE).But the fluoride plastic inner lining only is suitable in use below 200 ℃.Be higher than 200 ℃, this kind plastics then produce contraction distortion and aging speed is accelerated.Another kind of way is at reactor wall plating enamel glass.But enamel glass property is crisp, receive easily wall thermal shock and breakage, peel off.
A compound experiment is once only done with hydrothermal reactor in traditional laboratory.Yet the innovation of chemical synthesising technology requires the high production chemical synthesis process.The high production chemical synthesis process is meant and uses a microreactor array of being made up of various microreactors to carry out various synthetic reactions simultaneously.It is a kind of low cost, high efficiency experimental technique, has become the research means of biochemical field.Yet present microreactor array does not suppress the mechanism of solvent evaporation, can only can not be used to relate to the hydro-thermal reaction of HTHP as the reaction of solvent-free evaporation.
The utility model will provide a kind of novel structure of reactor, to solve the technical problem that the traditional water thermal reactor exists.The structure of reactor that the utility model provides also is applicable to the microreactor array.
