[2-[(2R,3S,4R)-3,4-dihydroxyoxolan-2-yl]-2-hydroxyethyl] octadecanoate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: The ditallowalkyldimethylammonium methylsulfate in the softener and antistat mixture was obtained as a commercial product from the Ashland Chemical Company. The sorbitan ester comprises the C16 and C18 alkyl mono, di, tri and tetra esters of sorbitan, isosorbide and small amounts of sorbitol (collectively "sorbitan esters") and was obtained as a commercial product from Glycomul Corporation as Glycomul S. This sorbitan ester mixture contains from about 52 to 59% by weight of C16 material and from about 41 to 49% C18 material. The sorbitan ester mixture further comprises from about 29 to 33% by weight of the monoester component, from about 28 to 38% by weight of the diester component and from about 23 to 32% by weight of the tri and tetra ester component with the remainder being unreacted material. The weight ratio of ditallowalkyldimethylammonium methylsulfate to sorbitan ester was about 7 to 3.

実験手順: 20.0 parts by weight of methacrylamide trimethylammonium hydrochloride as a main monomer of a polymer gel for a light scattering member was added to 33 parts by weight of distilled water. A solution formed by dissolving 0.1 part by weight of ammonium persulfate in 2 parts by weight of distilled water, 10.0 parts by weight of titanium oxide having an average diameter of 0.2 μm (refractive index: 2.7) as a light scattering material and 0.1 part by weight of N,N′-methylenebisacrylamide as a crosslinking agent were added to the resulting solution, to prepare a uniform solution by sufficiently stirring. The resulting dispersion solution was added, in a beaker, to a solution obtained by dissolving 1.0 part by weight of a sorbitol series surface active agent (Sorgen 50, trade name, produced by Dai-ichi Kogyo Seiyaku Co., Ltd.) as a dispersion stabilizer in 100 parts by weight of cyclohexane, followed by substituting with nitrogen, and then emulsified by stirring at a high speed with a rotary stirring blade at 10,000 rpm for 10 minutes. A solution formed were added to the resulting solution to prepare a uniform solution The resulting dispersion solution was added, in a beaker, to a solution obtained
