Chemical Structure
Basic Info
Propylene glycol, Chemical formula CH3CHOHCH2OH. Molecular weight 76.10. There is a chiral carbon atom in the molecule. The racemic type is a hygroscopic viscous fluid with a small spicy preference.
Particular gravity 1.036 (25/4 ℃), cold point -59 ℃. Boiling at 188.2 ℃ and 83.2 ℃ (1333 ), it is miscible in water, acetone, ethyl acetate, and chloroform, and soluble in ether.
Propylene glycol is soluble in several necessary oils, yet not miscible with petroleum ether, paraffin, and fats. It is a lot more secure to warm and light, and extra steady at low temperatures.
The boiling point of the left-handed body is 187-189 ℃, and the details rotation is [α] D20-15.0 °.
Propylene glycol can be oxidized to acetaldehyde, lactic acid, pyruvic acid, and acetic acid at high temperatures.
Chemical homes of propylene glycol
Colorless, viscous, and stable absorbing liquid, almost unsmelling and tasteless. Suitable with water, ethanol, and various natural solvents
Propylene glycol is an anemic, thick, and stable water absorbing fluid with a relative thickness of 1.0381. The refractive index is 1.4326. Surface area stress (20 ℃) 38mNm. Thickness (20 ℃) 60 5mPa s. Specific warmth capability (20 ℃) 2.49 kj/( kg. ℃). Warm of evaporation (101.3 kPa) 7Ukj/kg. Combustion warm (25 ℃) 1824 OkJ/mol 。 Flash point (open mug) 99 ℃. The self ignition point is 415.5 ℃. The critical temperature is 352 ℃. The vital stress is 6.1 MPa.
The preparation method of propylene glycol
The straight hydration approach of epichlorohydrin is a pressurized non catalytic hydrolysis approach. Epoxy lp and water at 150 N, 160 ℃, 0.78-0 Produced by direct hydration under a pressure of 98MPa, the reaction product is vaporized and distilled to acquire the finished product.
The indirect hydration technique of epichlorohydrin is prepared by indirectly moistening epichlorohydrin with water using sulfuric acid as a catalyst. The response equation coincides as above.
Straight catalytic oxidation of propylene.
Making use of propylene glycol
Propylene glycol is a resources for unsaturated polyester resins, epoxy resins, polyurethane materials, in addition to plasticizers, surfactants, emulsifiers, and demulsifiers.
Propylene glycol is utilized in the food industry as the solvent of essence and food pigment, tobacco moistening agent, mold inhibitor, fruit ripening preservative, pharmaceutical excipient, and so on. It can also be used as an antifreeze, warm carrier, and lubricant for food equipment.
