Abstract

The present invention relates to the field of organic compound synthesis, and specifically, relates to a sulfonate-type biomass surfactant based on a fatty acid methyl ester and a synthesis method thereof. A main component of city restaurant and kitchen swill waste oil is the fatty acid methyl ester. The sulfonate-type biomass surfactant based on the fatty acid methyl ester is prepared from the following steps: preparing fatty acid alkanolamide, and carrying out a sulfopropyl reaction. The sulfonate-type biomass surfactant based on the fatty acid methyl ester is applied in the field of oil production. The sulfonate-type biomass surfactant synthesized in the present invention has better surface activity and interfacial activity, is non-toxic, non-hazardous and degradable, does less harm to an environment and a stratum layer, can replace a conventional petroleum diesel-based surfactant, achieves purposes of resourceful comprehensive utilization of city restaurant and kitchen swill and added value improvement, and has a good application prospect; in addition, a synthesis reaction condition is mild, a preparation process is simple, and the process is reasonable, applying to scale production; the surfactant is used as an oil washing agent of a chemical flooding system in oil drilling, improves an oil washing effect, and thus improves a crude oil recovery rate.

Description

technical field

[0001] The invention belongs to the field of organic compound synthesis, and in particular relates to a sulfonate-type biomass surfactant based on fatty acid methyl ester as the main component in waste oil from kitchen waste and a synthesis method thereof, which is applied to oil exploitation. Background technique

[0002] About 4 to 6 million tons of waste oil are produced in urban kitchen waste in my country every year, and some of the waste oil flows into rivers, wasting in vain and polluting water bodies; another considerable part is processed into "refined oil" and returns to the dining table, posing a serious threat to my country's food safety . Fatty acid methyl esters prepared from kitchen waste oils are widely used as diesel fuel because of their good storage stability, low boiling point, easy fractionation, and low corrosion. In addition, with people's in-depth research on fatty acid methyl esters, its use is also expanding. The main use is as an in...
