Triethylene glycol physical properties

Vinyl Ethers. The principal commercial vinyl ethers are methyl vinyl ether (methoxyethene, C H O) [107-25-5], ethyl vinyl ether (ethoxyethene, C HgO) [104-92-2], and butyl vinyl ether (1-ethenyloxybutane, C H 20) [111-34-2]. (See Table 8 for physical properties.) Others such as the isopropyl, isobutyl, hydroxybutyl, decyl, hexadecyl, and octadecyl ethers, as well as the divinyl ethers of butanediol and of triethylene glycol, have been offered as development chemicals (see Ethers). 

Triethylene glycol dinitrate (TEGDN) is an explosive plasticizer of low sensitivity that has been used in some nitroceUulose-base propellant compositions, often in combination with metriol trinitrate. Butanetriol trinitrate has been used occasionally as an explosive plasticizer coolant in propellants. Its physical properties are Hsted in Table 7. 

Trimethylolethane trinitrate (metriol trinitrate) is not satisfactory as a plasticizer for nitrocellulose, and must be used with other plasticizers such as metriol triacetate. Mixtures with nitroglycerin tend to improve the mechanical properties of double-base cast propellants at high and low temperatures. Metriol trinitrate has also been used in combination with triethylene glycol dinitrate as a plasticizer for nitrocellulose. Its physical properties are Hsted in Table 7 (118-122).

A wide variety of plasticizers are suitable for PVB and PVF resins. For many years, the universally used plasticizer for PVB was triethylene glycol di(2-ethylbutyrate) [95-08-9] (6). More recently this has been supplanted by triethylene glycol di(2-ethylhexanoate) [94-28-0], tetraethylene glycol diheptanoate [70729-68-9], dihexyl adipate [110-33-8], 2-ethylhexyl diphenyl phosphate [1241-94-7], and a variety of other oligomeric ethylene glycol esters and ethers, and other adipate, phosphate, phthalate, sebacate, and ricinoleate esters (19,20,57-62). For PVF, diethyl, diphenyl, and dicyclohexyl phthalates, as well as tributyl, triphenyl, and tricresyl phosphates are useful plasticizers (21). By proper choice of plasticizer type and level, the physical-mechanical, chemical, and adhesion properties of these resins can be tailored for a wide variety of applications (see Plasticizers).
