Method for preparing diethyl oxalate by coupling CO

The invention discloses a method for preparing diethyl oxalate by CO coupling reaction. By applying a gas phase method, CO is coordinated with ethyl nitrite and is catalyzed by bimetallic supported catalyzer to couplingly generate crude diethyl oxalate, the reaction is a self-sealing circulation process, the CO gas mixed with the ethyl nitrite coming from a regeneration reactor is preheated and then enters into a coupling reactor, after the reaction, the gas is separated by condensation, so that the colorless and transparent condensed diethyl oxalate liquid is produced, and the uncondensed gas containing NO enters into the regeneration reactor to react with ethanol and oxygen in order to generate ethyl nitrite which is again circulated back to the coupling reactor for continuous use. The invention is carried out on the basis of previous laboratory research and under the background of industrial production and fulfils the continuous run examination of the bench scale test and pilot magnification under the condition of industrial operation, the temperature of the coupling reaction is low, and the concentration of products is increased. The method has the advantages of more energy saving, no pollution and high benefit. The total conversion rate of the CO generated by reaction is one hundred percent, and the selectivity of diethyl oxalate is over ninety six percent.

Preparation of high-temperature floamed ceramic

The invention provides a preparation method of a high temperature foam ceramics, which is characterized in that: zirconium diboride-aluminum oxide composite ceramic powder is prepared into ceramic slurry, polyurethane foaming plastic with certain bore diameter and porosity is soaked into the ceramic slurry so that the ceramic slurry evenly adheres to the surface of the pores of the polyurethane foaming plastic to form a ceramic slurry layer, which are then prepared into a polyurethane foaming plastic ceramic blank, and then are subjected to drying, degreasing and sintering, and the high temperature foam ceramics is prepared. The invention adjusts the high temperature resisting performance of the high temperature foam ceramics prepared by adjusting the ratio of zirconium diboride and aluminum oxide, therefore, the high temperature foam ceramics can resist high temperature and greatly expand working temperature scope; the high temperature foam ceramics prepared by the method can resist high temperature and keep chemical stability under high temperature condition; therefore, in high temperature working environment, the high temperature foam ceramics can be used repeatedly or continuously for the performances of thermal-shock resistance, oxidation resistance, molten steel erosion resistance, and the like, when being used in the filtration of molten steel, showing good performance.

Backup method of application program in communication terminal and communication terminal

The invention is applicable to the technical field of communication and provides a backup method of an application program in a communication terminal and the communication terminal. The backup method comprises the following steps of: detecting the current residual memory space of the communication terminal before downloading a new application program; obtaining the memory occupation value of the new application program; judging whether the current residual memory space is more than the memory occupation value of the new application program; if so, executing an application downloading step; otherwise, executing an application backup step; backing up at least one application program in the communication terminal into a server, automatically deleting the backup application programs in the communication terminal, and returning back to a memory judging step; and downloading the new application program to the communication terminal. Therefore, the problem that the installation is abandoned due to insufficient memory during or after the process of downloading the application program can be avoided, so that the time and communication flow of a user are effectively saved; and meanwhile, the user can selectively back up the application programs which are not usually used into the server, so as to facilitate the continuous use after the application programs are recovered.
