- Synthetic method of coconut diethanol amide
-
The invention particularly relates to a synthetic method of coconut diethanol amide. The synthetic method comprises the following steps that 1, raw materials fatty acid and diethanol amine (DEA) are pretreated and purified; 2, under N2 airflow protection, and the fatty acid and the diethanol amine (DEA) perform amidate and ammonolysis reaction; 3, finally adsorption treatment is performed by using activated carbon, and filtration is performed to obtain the coconut diethanol amide. The 1: 1 coconut diethanol amide prepared by adopting the method has the advantages of being high in purity, light in color and luster, light in smell, low in amine value and the like.

- Oil soluble molybdenum amine complex and preparation method thereof
-
The invention discloses an oil soluble molybdenum amine complex and a preparation method of the oil soluble molybdenum amine complex. The method adopts long-chain saturated fatty acid as the starting material, acylchlorination reaction is carried out on the long-chain saturated fatty acid and thionyl chloride to obtain 1-chloro saturated fatty acid, then amidation reaction is carried out on the 1-chloro saturated fatty acid and diethanol amine to obtain saturated fatty acid amide, and finally complexation is carried out on the saturated fatty acid amide and a molybdenum trioxide solution so as to obtain the oil soluble molybdenum amine complex. The prepared molybdenum amine complex has good oil solubility, solves the poor oil solubility, corrosion resistance, wear resistance and friction reduction and other problems difficult to overcome in existing products, at the same time significantly reduces the adding amount of high sulfur and phosphorus components, and has enormous boosting effect on organic molybdenum series lubricating products currently under research in China, thus promoting nationalization of high-end lubricating oil and efficient utilization and high added value of molybdenum resources.

- Sulfonate type biomass surface active agent and synthetic method
-
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.

- Low molecular weight PEI-based biodegradable lipopolymers as gene delivery vectors
-
Non-viral gene vectors play an important role in the development of gene therapy. In this report, different hydrophobic chains were introduced into low molecular weight (LMW) PEI-based biodegradable oligomers to form a series of lipopolymers (LPs), and their structure-activity relationships were studied. Results revealed that the nine polymers can condense plasmid DNA well to form nanoparticles with appropriate sizes (120-250 nm) and positive zeta-potentials (+25-40 V). In vitro experiments were carried out and it was found that LP2 showed much higher transfection efficiency both in the presence and in the absence of serum under the polymer/DNA weight ratio of 0.8 in A549 cells.

- Method for lowering the free fatty acid content in sebum using certain fatty acid amides
-
A method of lowering the free fatty acid content in sebum on the skin surface by topically applying a member of a certain class of fatty acid amides to the affected skin area. Oleic acid diethanolamide is illustrated as a representative of the useful class. After cleansing, rinsing and drying the skin area to be treated, the fatty acid amide formulation is applied thereto and left thereon for beneficial action to occur.
