Glycol ether solvents

Uses Preparation of butyl esters (e.g., butyl acetate, di-n-butyl phthalate), glycol ethers solvent for waxes, resins, gums, and varnishes hydraulic fluid ingredient in perfumes and flavors additive in deicing fluids polishes, floor cleaners, stain removers, and in some gasolines (antiicing) diluent for brake fluids humectant for cellulose nitrate.

Solvent cleaners are generally free of builder salts. The cleaning efficacy depends on solvent-type compounds, such as glycol ethers. Solvent cleaners are less effective on particulate soiling, such as mud on floors however, they are effective against oily soiling, particularly on modern plastic surfaces.

A large-scale use of epoxy resins is to make acrylic graft copolymers for interior linings of beverage cans (154). A solution of a BPA epoxy resin in a glycol ether solvent is reacted with ethyl acrylate (2-propenoic acid ethyl ester)... 

The industrial grade of propylene glycol is a valuable intermediate in the manufacture of alkyd resins used in paints and varnishes. Reaction of propylene glycol with an aliphatic alcohol or phenol yields the versatile glycol ether solvents (see Chapter 13). Propylene glycol is used in the manufacture of unsaturated polyester resins, as a solvent for printing inks, and in the synthesis of emulsifiers like propylene glycol monostearate.

TEFLON" FEP was commercialized in 1959. At that time there appeared to be no hope of synthesis of a thermoplastic perfluorinated polymer of any structure other than FEP. Within two years the situation had changed as the result of a series of unexpected discoveries. For several years, research on the synthesis of perfluorocarbon epoxides had been underway in Du Pont, culminating in the discovery of a route to hexafluoropropylene epoxide (HFP0 )[5]. By 1960 sufficient HFPO had been made to permit exploration of its polymerization. This work shortly turned up an unusual polymerization system consisting of CsF initiator and polyethylene glycol ether solvent. Under the proper conditions this same system could be used to effect the condensation of HFPO with perfluorocarbon acid fluorides to produce perfluoroalkoxypropionyl fluorides [6]. These intermediates could be readily converted to perfluoroalkyl vinyl ethers by pyrolysis of their acid forms. 

Ethylene is the most important intermediate in the chemical industry. The production volume was about 120 metric tonnes/year in 2007 and is expected to increase to approximately 180 metric tonnes/year by 2020 [1]. The main outlet for ethylene, roughly 60%, is used for polyethylene, followed by ethylene oxide, vinyl chloride and styrene. Ethylene oxide is a key material in the production of surfactants and detergents. It is mainly converted to ethylene glycol which ends up in, for example, polyethylene tereph-thalate and glycol ether solvents. Vinyl chloride and styrene are almost exclusively used to produce polyvinyl chloride and polystyrene, respectively. Ethylene is an intermediate for more than 50% of the polymer production volume.

Water soluble styrene acryHcs are processed via free radical polymerization in glycol ether solvents. The solvent is stripped by conventional or proprietary processes. Rosin based resins are processed molten at high temperatures up to 265 °C. These materials are flaked or pelletized and packaged in bags or bulk storage for further conversion.
