Propyne-PEG4-alcohol - Reference Information
| application | propynyl-tetramethylene glycol is a pharmaceutical intermediate, a raw material for chemical synthesis, and an international hot-selling PEGLINKER linking agent product and an adhesive curing agent in NEPE propellant. |
| preparation | 1.4g of potassium tert-butoxide, 2.0g of tetrapolyethylene glycol, 3.0g of propyne bromide and 95mL of tetrahydrofuran were added to a three-mouth flask equipped with a magnetic stirrer, a reflux condenser and a thermometer, respectively, and the reaction temperature was 30 ℃ and the reaction was 24h. Extraction with saturated salt aqueous solution, spin-evaporation of the upper liquid, and vacuum drying to obtain a viscous liquid product with 86.1% yield. the obtained product is cured with a certain azide curing agent with a functionality of 3.82. CuI is used as catalyst and triglyceride acetate is used as plasticizer to obtain the cured product propynyl-polyethylene glycol. |
