摘要:
Disclosed is a process for producing chlorine by oxidation of hydrogen chloride through a catalytic gas-phase reaction in the presence of a catalyst, wherein hydrogen chloride as a raw material is a by-product of synthesis of isocyanate by reacting phosgene and primary amine and oxidizing the hydrogen chloride through a catalytic gas phase reaction in the presence of a catalyst. The process is characterized by adjusting the sulfur content in carbon monoxide which is a raw material for the phosgene to 2000 vol. ppb or less.
摘要:
Provided is a hydrogen chloride oxidation reaction apparatus for producing chlorine by oxidizing hydrogen chloride through a contact gas phase reaction in the presence of a catalyst by using hydrogen chloride and oxygen as major raw materials, wherein the hydrogen chloride oxidation reaction apparatus includes a mixing portion for mixing the raw material gases and a transfer piping portion for transferring the mixed raw material gases from the mixing portion to a reactor for a contact gas phase reaction, and wherein a gas contact surface of the mixing portion and/or a part of a gas contact surface of the transfer piping is made of or covered with tantalum or a tantalum-tungsten alloy, as well as a hydrogen chloride oxidation reaction method using the same.

To provide a user with better experience of cooperation between an electronic business card processing program and a communication program when exchanging electronic business cards. Electronic business cards are stored in a DB server, which is one of storages for a communication program, as well as an electronic business card local file. Thus, even if a PC is a company's PC, for example, the electronic business cards can be viewed by accessing the DB server from another PC or the like outside an office. Further, the electronic business card processing program operates with the communication program as backend, however, the electronic business card processing program may not be installed on a PC in some cases. Even in such a case, the communication program alone can display received electronic business cards that are stored in the communication program local file on the screen of a display.
摘要:
The present invention relates to a multitubular catalytic gas-phase reaction apparatus, comprising a plurality of reaction tubes arranged in parallel, a baffle capable of changing the direction of movement of a heat medium introduced into a reactor shell to a direction perpendicular to the longitudinal direction of the reaction tubes, a space that is disposed in a region including a part of a section where the heat medium flows in the direction of the face of the baffle and does not have the reaction tubes arranged therein, and flow-adjusting rods, disposed in between the space and the reaction tubes, having the same longitudinal direction as that of the reaction tubes.

The present invention provides a method for removing sulfuric acid mist wherein a gas containing sulfuric acid mist is bubbled into an absorbing solution through a gas diffuser having pores with an average pore diameter of about 1,000 &mgr;m or less. This method allows simple and highly effective removal of sulfuric acid mist.
摘要:
A process is disclosed for a continuous, high temperature polymerization process for preparing a gel free polymeric product. The process comprises continuously charging into a reactor at least one monomer such that the reactor is filled to 100 percent of its usable volume. The reactor is maintained at an effective temperature for an effective period of time to cause polymerization of the monomers into a polymeric product, such that the polymeric product is formed substantially free of gel particles.
摘要:
A user interface suited for use on mobile devices for entering characters which may require one or more modifiers is disclosed. The interface may be implemented utilizing a touch screen interface on which a user engages the interface, is provided feedback, and removes the user's touch to enter a character. The interface presents a series of main, supplemental and modifier keys. Touching an interface button or main key presents a series of “petals” or supplemental keys emanating from the main key. Each petal or supplemental key may in turn present one or more sub petals or modifier keys emanating from the supplemental key. Each petal or sub-petal may represent another character or a modifier action. The characters and/or actions on the supplemental keys and modifier keys provide options for characters or modifiers which are dependent or related to the main input key.
摘要:
A novel information processing system, information processing method, program, and recording medium related to electronic business cards are provided. An information processing system for generating data of an electronic business card, stores personal information, and stores one or more presentation method data. Each of the presentation method data specifies a method for presenting the personal information in the electronic business card. The information processing system generates the data of the electronic business card by using the personal information and one of the presentation method data, when an instruction to use the data of the electronic business card is inputted.
摘要:
A hierarchical address book for an organization is implemented where employees are represented by user objects and departments are represented by department objects. Computer-readable media include executable instructions for displaying and navigating the hierarchical address book. Computer-readable media also include executable instructions for ordering a list of recipients of an electronic mail message as a function of the seniority rating of an object in the hierarchical address book.
