Here, we report the preparation of a series of Na+-doped Ca(OH)2 in nanocrystalline form using a very simple method, and investigation of their catalytic activities towards one step aminolysis and transesterification of used cottonseed oil. The catalyst prepared by doping 3.5 wt% Na in Ca(OH)2 was found to exist in nanocrystalline form (particle size = 25-30 nm) as suggested by TEM and DLS studies and found to have the basic strength of 15.0 2 was used as a solid catalyst towards the aminolysis and transesterification of used cotton seed oil with diethanolamine and methanol, respectively. The catalyst was found to complete the aminolysis and transesterification of a variety of feedstocks even at room temperature and shows excellent reusability.

Paragraph 0061, (2017/07/19)
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.

Paragraph 0040; 0041, (2017/03/14)
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.
