Subcritical water (SCW) is exactly under the pressure of appropriateness, water is heated to more than 100 ℃, during the high temperature of critical-temperature below 374 ℃, make it still remain on the high-temperature high pressure water of liquid condition, at this moment very big variation can take place in the character of water, its polarity can reduce on the one hand, resistance to mass tranfer diminishes, also can increase organic solvability, be similar to organic solvent, on the other hand, along with temperature near critical point, the acid-base catalysis ability of water strengthens greatly, can replace the classical acid base catalyst to be used for acid base catalyzed reaction to a certain extent, removes the application of acid base catalysator and the last handling process of soda acid from, pollution sources have been eliminated, because its character is adjustable with temperature and pressure, can design the reaction conditions needed as required in addition, the control reaction is carried out towards the direction of expectation.
Hydrolysis can both take place in a lot of organic compounds in normal-temperature water, but as the adding of no strong acid or alkali catalyst, reaction conversion ratio can be lower, and the reaction that in SCW, is hydrolyzed, just can reduce even eliminate the use of strong acid and strong base catalyst, thereby removed the neutralization of reacted product from and step such as separated, can control pH value and final control reaction conversion ratio and the product composition of SCW simultaneously by conditions such as control reaction temperatures.
But, because its reaction requires HTHP, than higher, general present employing high-pressure reaction pot carries out intermittently or batch reactions to the requirement of equipment, and the extent of reaction is controlled automatically in the course of reaction like this, and sample analysis etc. is not too convenient, operating process is not easy control, also is unfavorable for amplifying producing, in order to overcome the defective of present prior art equipment, we develop a kind of subcritical water pipe reaction equipment, and this equipment has the following advantages; Equipment is simple, and can be simultaneously existing control reaction temperature, pressure and the time automatically, course of reaction can the grab sample analysis, the control course of reaction of precise and high efficiency.
Summary of the invention
