Synthesis of polyethylene glycol distearate

Abstract:

polyethylene glycol distearate was synthesized by using phosphorous acid and sulfuric acid composite catalyst. The optimum process conditions were: n acid: n alcohol 2.8:1(mol:mol), the dosage of composite catalyst was 1.0% (based on polyethylene glycol), the reaction temperature was 150 ℃, the reaction time was 5h, and the vacuum degree was 97.3kPa.

Preparation of polyethylene glycol distearate and determination of its thickening property

Abstract:

Polyethylene glycol distearate was prepared by transesterification under normal pressure with polyethylene glycol (6000) and monoglyceride Stearate as raw materials and p-toluenesulfonic acid as catalyst. The optimum reaction conditions were determined by orthogonal experiment. Combined with the experimental principle and method, the effects of catalyst, reaction temperature, reaction time and material ratio on the reaction were discussed, the viscosity of polyethylene glycol distearate solution with different concentrations was measured. The optimum conditions for the synthesis reaction are as follows: the amount of catalyst is 2%(molar ratio), the reaction temperature is 130 ℃, the time is 4H, and n (stearate):n (polyethylene glycol) = 4:1. Under these conditions, the yield was 98%.

Preparation and thermal properties of polyethylene glycol distearate and its core-shell structure for energy storage

Abstract:

polyethylene glycol distearate was prepared by the esterification reaction of low molecular weight polyethylene glycol and acyl chloride stearic acid by emulsion method, the core-shell structure materials with phase transition function were prepared.

Polyethylene glycol distearate as a carrier of lutein

Abstract:

Amphiphilic polyethylene glycol distearate was synthesized and characterized by IR and NMR. Using pyrene as a model drug, the critical micelle concentration of polymer micelles was determined by fluorescence probe method, and the critical micelle concentration was 3.98 × 10 ~(-2) g/L(1.53 × 10 ~(-5)). mol/L). Lutein was embedded with polyethylene glycol distearate as carrier, and lutein-loaded polymeric micelles were prepared by solvent evaporation method. The results of dynamic light scattering showed that the micelles were monodisperse and the average particle size was 180 nm. Atomic force microscopy showed that the prepared micelles were generally spherical and uniform in size. The drug loading rate of lutein in the drug loaded micelles was 10.36%, and it had good water solubility.
