Abstract
Tests have been carried out to measure the temperature dependence of static susceptibility of a magnetic fluid stabilized with polypropylene glycol (PPG) in propanol, ethyl ether and propylene oxide. The use of propylene oxide provides the widest temperature range for measurements of fluid susceptibility. The coagulation stability of the PPG-stabilized magnetic fluid against ethylene glycol and 1,4-butylene glycol is investigated. It has been shown that ethylene glycol can be used to separate PPG magnetic fluid into fractions. The fluid separation begins as soon as the volumetric fraction of ethylene glycol exceeds 30%. Butylene glycol is unsuitable for fractionation but can be used to remove excess surfactant - PPG.
