IPC: C07C57/05
Filed: 1980-02-12
Abstract: PURPOSE: To reduce the amount of steam, specify the concentration of fine solid particles in the inlet gas of a reactor in the former stage and prolong the life of a catalyst, by circulating part of the outlet gas of a reactor as a diluent in obtaining methacrylic acid through the catalytic vapor phase oxidation of isobutylene, etc. in two stages.  
     CONSTITUTION: Isobutylene or a hydrocarbon mixture consisting of the isobutylene essentially or t-butyl alcohol is oxidized in the vapor phase catalytically in two stages to prepare methacrylic acid. After the reaction, the outlet gas from a reaction in the latter stage is fed into a condensing apparatus to collect condensible components, e.g. methacrylic acid or water. The remaining waste gas is partly circulated through the oxidation reactor in the former stage instead of steam. The concentration of fine solid particles in the inlet gas of the reactor is adjusted to 0.5g/Nm 3  or below, preferably 0.1g/Nm 3  or below. The volume of the gas to be circulted for use is usually 5W90% based on the outlet gas. The concentration of the fine solid particles, e.g. methacrylic acid, adjusted to the value described above prevents the adsorption of the fine particles to the surface of the catalyst.

Title: Surface structure analyzing device
Inventor: DOI SEIZO
IPC: G01N23/227
Filed: 1987-01-28
Abstract: PURPOSE:To allow the minor surface measurement performable on a laboratory scale by using an intensity-modulated incident electron beam. CONSTITUTION:An incident electron beam is radiated to a sample while its energy is changed, the quantity of Auger electrons emitted from the said sample is measured, the EXAFS vibration term superimposed on the resulting decay curve is Fourier-transformed, thereby the crystal structure of the fine surface of the said sample is analyzed. In this device, the incident electron beam is particularly intensity-modulated. Electrons radiated on a solid sample are intensity-modulated at the frequency omegao, on the other hand the energy distribution of Auger electrons not intensity-modulated is I(E) (the number of Auger electrons having the kinetic energy of E), then the energy distribution of the Auger electrons emitted from the sample by the radiation of the electrons intensity-modulated at the frequency omegao is indicated as I(E) sinomegaot. Therefore, if only the signal component of the frequency omegao is detected by a lock-in amplifier, the true spectrum I(E) can be obtained. That is, according to this method, the distortion by potential modulation is not generated, end only the omegao component is detected, thus the noise component of thermoelectrons or the like is reduced.

Filed: 1988-01-27
Abstract: PURPOSE:To obtain a hot water heater which automatically removes a hypochlorous acid and a trace of organics contained in a tap water at the time of every use and boils the safe and delicious hot water by installing one edge of a string- shaped activated carbon fiber at the inlet side channel of a heater pipe, and inserting the other edge into a heater pipe like a streamer. CONSTITUTION:Since a check valve 2 prevents the reverse flow of the water, first, the water contained in a heater pipe 5 becomes the hot water and almost all the water goes out to a receiving cut p. Next, when the inside of the heater pipe 5 becomes almost empty, the new water comes from a water storing cup 1 into the heater pipe 5, and it is boiled and drops to the receiving cup 9. By repeating this, the whole tap water in the water storing cup 1 becomes the hot water, and is retained in the receiving cup 9. Thereafter, the receiving cup 9 receives heat from a heat plate 7, and the heat is insulated. Since the tap water surely touches an activated carbon fiber 10 during an action, the hypochlorous acid and a trace of the organics are adsorbed and removed, and the safe and delicious hot water can be obtained.
