Embodiment Construction

[0025] The following examples describe the present invention in more detail:

[0026] Prepare the raw materials according to the mass ratio of 1.0-3 parts of LAS, 1.5-4.5 parts of AES, 7.5-22.5 parts of sec-butanol, 10-30 parts of mixed benzene and 55-165 parts of water. Prepare an aqueous alcohol solution in water, add LAS and AES into the aqueous alcohol solution to dissolve them, and then add mixed benzene dropwise to obtain a microemulsion product.

[0027] Prepare the raw materials according to the ratio of 1.0 parts of LAS, 4.5 parts of AES, 10 parts of sec-butanol, 10 parts of mixed benzene of toluene and xylene 1:1 and 60 parts of water, and first dissolve the sec-butanol in water To obtain an aqueous alcohol solution, add LAS and AES to the aqueous alcohol solution to dissolve them, and then add mixed benzene dropwise to obtain a microemulsion product.

[0028] According to the mass ratio of 3 parts of LAS, 4.5 parts of AES, 22.5 parts of sec-butanol, 30 parts of mix...

Abstract

The invention provides a micro emulsion and process for preparation, wherein the mass ratio being LAS 1.0-3 parts, AES1.5í½4.5 parts, butanol 7.5-22.5 parts, mixed benzol 10-30 parts and water 55-165 parts.

Description

(1) Technical field [0001] The invention relates to a composition, in particular to a composition which can be used for oil stain cleaning and oil field tertiary oil recovery. (2) Background technology [0002] Most of the metal cleaning agents currently produced and used in my country contain chemical components such as strong acids, strong alkalis, phosphates and aluminum salts. These products have poor stability and poor microbial degradation, and may cause serious harm to humans, animals and plants, have a lot of foam, pollute river water and underground resources, and cause varying degrees of damage to the cleaned metal surface. With the increase in the variety of cleaning agents, the requirements for the environment and quality are getting higher and higher. Metal detergents are required not only to have superior performance, but also to be "green" products, non-toxic and non-polluting. (3) Contents of the invention [0003] The purpose of the present invention is ...
