On October 4, 1989, Hanayama, Naoki; Nakagawa, Kazuo; Onishi, Akiyoshi published a patent.HPLC of Formula: 110729-26-5 The title of the patent was Preparation and testing of tris(carboxyalkylphenyl) phosphites as antioxidants. And the patent contained the following:
The title compounds [I; R1 = tertiary hydrocarbyl; R2 = (substituted) aralkyl, aryl, cycloalkyl; n = 0-2], useful as antioxidants for organic materials, e.g., polymers, were prepared Thus, 3,4-(Me3C)(HO)C6H3(CH2)3CO2Me (preparation given) in PhMe containing pyridine was treated with PCl3 at 70° and the mixture was refluxed 6 h to give I (R1 = Me3C, R2 = Me, n = 2). I effectively stabilized polypropylene at 230° against mol. weight loss. The experimental process involved the reaction of Octadecyl 3-(3-(tert-butyl)-4-hydroxyphenyl)propanoate(cas: 110729-26-5).HPLC of Formula: 110729-26-5
