Preparation method of diethylene glycol dibenzoate (2013
Abstract: The invention discloses a method for producing an environmentally friendly plasticizer diethylene glycol dibenzoate. The method includes the steps of 1) firstly feeding an oil phase in which benzoic acid is dissolved and diethylene glycol to an esterification reactor at a certain ratio, and gradually converting a benzoic acid component and the diethylene glycol into a diethylene
Diethylene glycol monobutyl ether adipate as a novel
Polylactide (PLA) was successfully plasticized by blending with diethylene glycol monobutyl ether adipate (DGBEA). The results showed that PLA and DGBEA had close solubility parameters, so PLA was miscible with DGBEA. The dynamic storage modulus and complex viscosity in the melt state of the blends decreased compared with neat PLA. DGBEA lowered the glass transition temperature and the cold
