Abstract

The invention discloses a stable and medium-yield oxidant for oil production and a preparation method thereof, and the stable and medium-yield oxidant comprises the following components in parts by weight: 3-6 parts of potassium permanganate, 20-30 parts of a 0.5 mol/L potassium hydrogen persulfate aqueous solution, 5-8 parts of sodium chlorate, 10-15 parts of 2-iodobenzoic acid, 3-5 parts of a stabilizer, 1-2 parts of an accelerant, 1-2 parts of a buffer agent, 10-15 parts of ammonium peroxydisulfate, 3-5 parts of 3-(2, 3-epoxypropoxy) propyltrimethoxysilane and 100-120 parts of a high-boiling-point solvent. 1-5 parts of a 3% sodium bicarbonate aqueous solution and 200 parts of pure water. Taking a strong oxidant potassium permanganate as a raw material to react with a potassium hydrogen persulfate aqueous solution and sodium chlorate to obtain a first preparation participant; according to the method, 2-iodobenzoic acid is used for preparing turbid liquid, the turbid liquid and a first participant are stirred, washed and dispersed and then cooled to separate out a product, the prepared oxidizing agent is stable in property, the viscosity of the turbid liquid is controlled through ionization, and the purity of the oxidizing agent in the preparation process is further controlled.

Description

technical field [0001] The invention relates to the technical field of medicinal chemical synthesis, in particular to a stable and medium-yield oxidant for oil production and a preparation method thereof. Background technique [0002] At present, oil products such as environmentally friendly solvent oil, metal working oil, ink, rubber oil, and refrigeration oil have been widely studied in recent years due to their special properties. The research directions mainly focus on: 1. Increase the output; 2. Improve the physical and chemical properties; 3. The production process is close to the requirements of environmental protection. [0003] Based on this, in the oil production process, the use of oxidants has an important effect on improving its production and its own properties. [0004] At present, the choice of oxidant, such as the commonly used o-iodoyl benzoic acid, has become an ideal oxidant due to its mild reaction performance, high selectivity, mild reaction conditions...
