    Propylene glycol is also known as 1,2 - propylene glycol, monopropylene glycol, propanediol-1,2, Propylen Glycol, Monopropylene glycol, MPG, Propane-1,2-diol, PGM, Propane-1,2-diol, Glikol monopropylenowy, 1,2-dihydroksy propan, 1,2-propanediol.

    Propylene glycol (propanediol) C3H6 (OH) 2 molecular weight 76.09. There are 2 isomers known: 1,2-propylene glycol CH3CHONCH2OH (1,2-propanediol) and 1,3-propylene glycol CH2OHCH2CH2OH.

    Propylene glycol is a colorless viscous hygroscopic liquid, sweetish in taste and odorless. Propylene glycol (propanediol) is an aliphatic dihydric alcohol.

    Boiling point 189oС, molecular weight 76.094; viscosity at 20 ° C 45.66 centipoise (cps); flash point 111.1oС, diatomic alcohol СН3СН (ОН) СН2ОН.

    Propylene glycol is completely miscible with water (dissolution occurs with the release of heat). Propylene glycol dissolves well most of low molecular weight oxygen and nitrogen-containing organic compounds such as monohydric alcohols, ethylene glycols and their ethers and other glycols, organic acids, aldehydes and ketones, esters, amines and other nitrogen-containing substances. Propylene glycol is also well miscible with diethyl ether, ethylene chlorohydrin, chloroform, turpentine, acetone and many other organic solvents.

    Limitedly soluble in benzene. One of the interesting properties of propylene glycol is its ability to dissolve both hydrophilic and hydrophobic substances, which allows it to mix substances that do not mix by themselves.

    With a number of compounds, propylene glycol forms azeotropic mixtures, i.e. such mixtures that are not fractionated by distillation. Forms azeotropic mixtures with aniline, (mp = 179oC; 43% propylene glycol by mass), o-xylene (mp = 135.8oC; 10.0%), toluene (mp = 110.5oC; 1.5%).

    Propylene glycol in the production of plastics and polymers

    Plasticizer Humidifier for parquet, furniture Base of unsaturated polyester resins, polyurethanes

    When interacting with triphenyl phosphate, phosphorus-containing compounds are formed, which are polymer stabilizers and are part of non-combustible polyurethanes. Of industrial importance are linear polyesters obtained from propylene glycol and dicarboxylic acids containing aromatic or several methylene groups. Depending on the composition of the feedstock, the resulting polyester has hydroxyl or carboxyl groups at the ends. Of particular importance are polyesters of unsaturated acids or mixtures of saturated and unsaturated acids, which are then crosslinked with various vinyl compounds.

    Unsaturated polyesters are widely used for various coatings and for the production of reinforced plastics, in particular, fiberglass. Polyester resins with good mechanical properties at high and low temperatures, as well as high chemical activity, are obtained by the interaction of propylene glycol with polyhalide polyphenyls and the resulting compound with organic acids.
