Embodiment Construction

[0014] At normal temperature and pressure, add 20 grams of potassium permanganate to 50 grams of acetone, fully dissolve, then add 30 grams of hydrogen peroxide, and age for 4.5 hours to make A solution; add 20 grams of potassium permanganate to 280 grams of ether Ferrocene, stirred to make it fully dissolved and aged for 4.5 hours to make B solution; mixed with 300 grams of methanol and 200 grams of acetone, added 100 grams of cerium nitrate (rare earth salt) to fully dissolve, and aged for 4.5 hours. into C solution. The three aged solutions of A, B, and C are mixed and then fully stirred, and the industrial gas rare earth additive is obtained after aging for 50 hours.

Abstract

The invention discloses a preparing method of industrial gas rare earth additive, which comprises the following steps: adding acetone into kalii permangana at normal temperature and normal pressure; dissolving completely; adding into hydrogen dioxide solution; aging; producing A solution; adding ether into bis iron; stirring to dissolve completely; aging; producing B solution; mixing methyl alcohol and acetone; adding into rare earth salification; dissolving completely; aging; producing C solution; mixing A, B and C solutions with finite proportion; stirring completely; aging; getting the additive. This additive possesses merits of safe and economical, which can be added into by-product of oil with 4-6 per mill proportion and replace the ethine gas.

Description

technical field [0001] The invention relates to a method for preparing rare earth additives for industrial gas, in particular to a method for wet preparation of rare earth additives. Background technique [0002] The development of industrial gas has a history of hundreds of years. With the continuous progress of industrial production and the continuous improvement of people's understanding of environmental energy science, the requirements for industrial gas technology products are also getting higher and higher. [0003] Acetylene gas is a traditional industrial gas, its chemical properties are active, explosive (explosion limit is 2.4-80%), and extremely dangerous. The molecular structure of acetylene at normal temperature and pressure is an unsaturated bond, and it is very unstable when heated. When the temperature is higher than 200 ° C, a polymerization reaction will occur, which will cause the temperature and pressure to rise continuously and cause an explosion. It is...
