9005-08-7 - Preparation of polyethylene glycol distearate and determination of its thickening property
from VIP Journal Professional Edition
Author:
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%.Key words:

from hownet
Author:
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. The esterification products and core-shell structure materials were characterized by FT-IR,DSC,TG and polarized light microscopy. The solid-liquid phase transition temperature of PEG200 distearate is 30 ℃ ~ 35 ℃, and the phase transition enthalpy is 95J/g. The enthalpy of phase transition of core-shell material is 32J/g.

Zhao Shan Cui , Wang Baoqi , Jiang Chuan , Guo Yanling
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.Key words:
