of the structure of linolenic acid (). Hartley P.
Methyl oleate, 1 was obtained from palm methyl esters through removal of saturated esters in a urea complex formation followed by silver nitrate impregnated silica gel column chromatography. The oleate was then reacted with 2,3-O-isopropylidene-D-glyceraldehyde 2, to form an aldol compound which, after lactonization, formation of tosylate and cyclic cyanohydrin, and oxidation of the double bond afforded 2-(6-carbomethoxyhexyl)-4(R)-hydroxy-2-cyclopenten-1-one 11, a prostaglandin intermediate.

To prepare oleic acid, the olive oil is saponified with potash, and lead acetate added; the lead salts are separated, dried, and extracted with ether, which dissolves the lead oleate; the solution is then treated with hydrochloric acid, the lead chloride filtered off, the liquid concentrated, and finally distilled under diminished pressure.

The exploration of the preparation methods for ultralong hydroxyapatite nanowires plays a vital role in manufacturing the raw material of the fire-resistant inorganic paper. The team developed a calcium oleate precursor solvothermal method for the preparation of ultralong hydroxyapatite nanowire by using a variety of alcohols. Its length reaches more than 100 microns, with the maximum even close to 1000 microns (Y. Y. Jiang et al., Solvothermal Synthesis of Submillimeter Ultralong Hydroxyapatite Nanowires Using Calcium Oleate Precursor in A Series of Monohydroxy Alcohols, Ceramics International, 41, 6098-6102 (2015)). The calcium oleate precursor solvothermal method is extended to be applied in a variety of different soluble phosphates, which are used as the phosphorus source for the preparation of ultralong hydroxyapatite nanowires (Y. G. Zhang et al., Ultralong Hydroxyapatite Nanowires Synthesized by Solvothermal Treatment Using A Series of Phosphate Sodium Salts, Materials Letters, 144, 135-137 (2015)). In addition, the good repeatability of ultralong hydroxyapatite nanowires is demonstrated through the large-scale preparation technology (10-liter volume autoclave). The team is now carrying out the exploration for the low-cost preparation technology of ultralong hydroxyapatite nanowires.
