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.

Here, we report the solvent-free one step preparation of fatty acid amides and fatty acid alkyl esters from low quality triglycerides using a solid catalyst. A series of Na+ modified CaO has been prepared in the form of nanoparticles by a modified incipient-wetness impregnation method, and used as a solid catalyst for aminolysis and alcoholysis of triglycerides. The prepared catalyst 3-NaC/CaO-450 (3 wt% Na impregnated in CaO) was found to exist in nanoparticle form (particle size = 25 nm) as suggested by TEM, DLS and powder XRD studies, have a surface area of 10.9 m2 g-1 (BET method) and found to have the basic strength of 15.0 H- 18.4 as supported by the Hammett indicator test. The catalyst was found to complete the aminolysis (5 wt% catalyst; 6:1 molar ratio of diethanolamine/oil; 110 °C) with excellent recyclability and is also equally efficient for the alcoholysis (5 wt% catalyst; 12:1 molar ratio of methanol/oil; 65 °C) of used cotton seed oil.

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.
