What is Polypropylene Glycol?

Polypropylene glycol is a polymer with the molecular formula H(C3H6O)nOH, an anemic to light yellow thick fluid. Not unpredictable. Non-corrosive. The molecular weight of basic products is 400 ~ 2050. Decreased molecular weight polymers are soluble in water. Higher molecular weight polymers are just a little soluble in water and soluble in oils, numerous hydrocarbons, and aliphatic alcohols, ketones, esters, and so on. The hydroxyl teams at both ends of the bit can be esterified to establish monoesters or diesters. Its monoester is a nonionic surfactant and can furthermore respond with alcohol to develop ether. It is a solvent for vegetable oils, materials and paraffin, and is furthermore used to prepare alkyd resins, emulsifiers, demulsifiers, lubricants and plasticizers. It is originated from the condensation of propylene oxide and propylene glycol under high pressure or in the visibility of an acidic chauffeur.

Polypropylene Glycol Properties and Applications

1. Polypropylene Glycol collection is soluble in toluene, ethanol, trichlorethylene and different other natural solvents. PPG200, 400 and 600 are soluble in water and have lubrication, solubilization, defoaming and antistatic frameworks. PPG-200 can be used as a dispersant for pigments.

2. In cosmetics, PPG400 is made use of as an emollient, conditioner, and lube.

3. Profited from as anti-foaming rep in surface areas and hydraulic oil, anti-foaming affiliate in synthetic rubber and latex handling, cooling depictive and coolant for comfy transfer fluids, and thickness improver.

4. Utilized as an intermediate in esterification, etherification and polycondensation activities.

5. Made use of as launch affiliate, solubilizer, additive for artificial oils, additive for water-soluble cutting liquid, roller oil, hydraulic oil, warmth lubricating substance, inner lubricating substance and outdoors lube for rubber.

6. Polypropylene Glycol-2000 ~ 8000 has extraordinary lubrication, anti-foaming, cozy and freeze resistance and numerous various other household or business residential or commercial properties;

7. Polypropylene Glycol-3000 ~ 8000 is mainly made use of as a part of mixed polyethers to generate polyurethane foam;

8. PPG-3000 ~ 8000 can be made use of to develop plasticizers and lubes perfect or after esterification;

9. This product can be taken advantage of as the base product for everyday chemicals, drugs and oils.

Polypropylene Glycol Synthesis Method

1. Polymerize glycerol and fine-tuned propylene oxide under the catalysis of potassium hydroxide at a temperature level of 90 to 95 ° C and a stress of 0.4 to 0.5 MPa. After that lower the temperature to 60 to 70 ° C, press the material into the neutralization pot, add water while mixing to counteract the excess potassium hydroxide, and then add phosphoric acid at 60 to 70 ° C to counteract to a pH of 6 to 7, and afterwards gradually raise the temperature to 110 ~ 120 ℃, vacuum dehydration and filtering.

2. Made from the enhancement response of propylene glycol polymer and water.
