oJà/mu From recent literature Brake fluids with improved characteristics can he prepared from 10'/ to 25V by volume of a lubricant, such as the mono- or diricinoleate of ethylene glycol, and 45'/ to 70* hy volume of a proper diluent, such as ethylene glycol. Corrosion inhibitors and other ingredients may he added in small amounts when required.
Flameproofing of certain papers is accomplished by using glycol monosulfates having a ratio of carbon to hydroxyl of between one and two. Such an agent can be prepared by reacting ethylene glycol (620 g.) with 1000 g. of concentrated sulfuric acid below 40° C. Neutralization can be carried out with an aqueous solution of a suitable base, such as ammonia or ethanolaminc.
Epoxide compositions which convert to water-insoluble, infusible products can be prepared from one part by weight of a polyepoxidc (prepared from the reaction of an epihalohydrin with a polyhydric alcohol, such as ethylene glycol, followed by dehydrohalogenation) with two-thirds to three parts by weight of a resinous epoxide (prepared by reaction of an epihalohydrin with a polyhydric phenol salt). Related products are obtained by the addition of small amounts of certain phenols to the epoxide mixture. Such epoxide compositions are valuable as organic bonding or cementing agents.
Antirusting compositions are conveniently prepared by reacting an anhydride of a dicarboxylic acid with a glycol, such as ethylene glycol, and with a monohydric alcohol. A further quantity of anhydride is finally condensed with this ester to produce the antirusting agent, which is particularly useful in turbine oils.
