  • Biologically degradable compositions
    Patent number: 7825163
    Abstract: A process for making a biodegradable composition involving: (a) providing from about 20 to 80% by weight of C8-22 fatty alcohol; (b) providing from about 20 to 80% by weight of a ring opening product of a C8-18 1,2-epoxyalkane with ethylene glycol; (c) combining (a) and (b) to form a reaction mixture; and (d) reacting the reaction mixture with ethylene oxide, with the proviso that the ethylene oxide is used in an amount of from about 5 to 100 mol ethylene oxide per mol of free OH groups present in the reaction mixture.

  • Polyol Ester for Transformers
    Publication number: 20080033201
    Abstract: A dielectric insulating fluid composition for a transformer including a trimethylol propane ester corresponding to general formula I: where R1, R2, and R3 are the same or different and each represents a linear or branched alkyl group containing 5 to 11 carbon atoms, where an ester having a viscosity of <23 mm2/s at 40° C. and a fire point of >300° C. is provided.
