| introduction | dipropylene glycol (DPG for short) is a colorless, odorless liquid at room temperature, non-corrosive, little irritation to skin, low toxicity and wide application. |
| application | dipropylene glycol is an alcohol organic substance, which is mainly used in the fields of high-quality raw materials such as spices, cosmetics, detergents, food additives, etc. The latter has relatively low price and is widely used as a raw material for the production of industrial solvents that do not require high DPG quality, unsaturated polyester and nitro fiber varnish. |
| preparation | in a 5L reactor, 30g of alkali catalyst sodium methoxide, 750g of propylene oxide, 2250g of propylene glycol, nitrogen filled to 0.3MPa, stirring is started, heating to 110 ℃ within 30 minutes, nitrogen is gradually released during the heating process, the pressure in the reactor is kept at 0.3MPa when the temperature is raised to 120 ℃, and the reaction time is 2 hours. After the reaction, it is cooled and the liquid material in the kettle is pressed out. The reaction product was analyzed by gas chromatography, and the purity of the product was 99.87%. The freezing point of the product obtained under the condition of alkaline catalyst is 4 ℃. |
