Embodiment Construction

[0010] Referring to Fig. 1, the reactor (1), platinum tube (2), spin tube washing bottle (3), cold trap (4), fume hood (6) are assembled into one body through connecting pipe (5) according to their system functions .

[0011] During use, the gaseous fluorine is fed into 2% sodium hydroxide solution to prepare, with a platinum tube (2) with an internal diameter of about 2mm 2 The air flow passes into the 2% NaOH solution contained in a glass reactor (1) at a speed of 1-3L / h, and the alkali liquor flows out from a higher position storage at a speed of 2L / h, and passes through the reactor (1) ), make the released mixed gas pass through a coil washing bottle (3) filled with water to absorb unreacted F 2 , and then the oxygen difluoride is condensed in two glass gas traps (4) cooled with liquid oxygen through the connecting pipe (5). The product is pumped at -183°C to 20mmHg, so that most of the O dissolved in the liquid oxygen difluoride can be removed 2 , fractionate oxygen di...

Abstract

The invention discloses technology for preparing oxygen difluoride. A device of the technology is mainly formed by assembling a reactor, a platinum pipe, a spiral pipe washing bottle, a cold trap and a draught cupboard into a whole through connecting pipes according to system functions. The technology for preparing the oxygen difluoride has the advantages of idealism, reasonable design and convenient use.

Description

Technical field [0001] The invention relates to a technology for producing oxygen difluoride in the chemical synthesis industry, in particular to a technology for preparing oxygen difluoride, which is suitable for chemical synthesis of oxygen difluoride. Background technique [0002] At present, oxygen difluoride is an important raw material in the chemical synthesis industry and has a wide range of applications, but the production process is complicated, the cost is high, and the product quality is poor. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a process technology for preparing oxygen difluoride. The technology is not only reasonable in process and simple in preparation, but also has easy-to-obtain raw materials, does not produce by-products, has high product yield and high utilization rate of raw materials. [0004] The technical scheme adopted in the present invent...
