Preparation method of substituted aryl organic phosphate nucleating agent

The invention relates to a preparation method of a polypropylene nucleating agent substituted aryl organic phosphoric acid metal salt. The method effectively solves the problems of low production efficiency, poor continuity, poor safety and low yield of the existing production method. The preparation method comprises the following specific preparation steps: 1, mixing substituted aryl phenol and a formaldehyde aqueous solution in a solvent, adding an emulsifier and an acid, heating to 80-100 DEG C under the protection of nitrogen, carrying out a reflux reaction, and ending the reaction after the reaction is qualified through detection; adding a demulsifier to separate a water layer, and dehydrating a solvent layer; 2, cooling the solution to 10-50 DEG C, adding phosphorus oxychloride, stirring and dropwise adding an acid-binding agent, after dropwise adding is finished, keeping the temperature, detecting to be qualified, adding water to dissolve generated hydrochloride of the acid-binding agent, separating a water layer, dissociating the water layer by using liquid caustic soda, dehydrating and recovering the acid-binding agent, and retaining a solvent material liquid layer; 3, heating the solvent feed liquid to 40-70 DEG C, dropwise adding metal alkali or a salt solution, and cooling after the reaction is finished to obtain a target product crude product; and 4, dissolving the target product, namely a crude product, with a solvent, decolorizing, and recrystallizing to obtain the target product. The preparation process is simple and short, and the obtained product is relatively high in purity and yield.

Experimental and theoretical investigations of the antioxidant activity of 2,2′-methylenebis(4,6-dialkylphenol) compounds

The antioxidant activity of two primary antioxidants, 2,2′-methylenebis(4-methyl-6-tert-butylphenol) (MMBPH2) and 2,2′-methylenebis(4,6-di-tert-butylphenol) (MDBPH2), has been studied using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. The synthesized compounds have been successfully characterized systematically using elemental analyses, infrared, 1H NMR and 13C NMR spectra and GC–MS. Importantly, it has been found that the compound MMBPH2 in particular is more active in DPPH radical scavenging. In addition, density functional theory calculations (B3LYP) have been used to predict the antioxidant activity and predict structural geometries of the compounds in the gas phase.
