    摘要: 1,2-Dichloro-1,1-difluoroethane is useful as a power fluid with particular suitability for moderate scale Rankine cycle applications based on systems with moderate temperature heat sources. The fluid is utilized in a Rankine cycle application by vaporizing the fluid by passing the same in heat exchange relationship with a heat source and utilizing the kinetic energy of the resulting expanding vapors to perform work. In this manner heat energy is converted to mechanical energy. The fluid is particularly advantageous in a dual cycle system consisting of a Rankine power cycle combined with a vapor compression cooling or heating cycle.BACKGROUND OF THE INVENTION

    摘要: A method for preparing polyurethane and polyisocyanurate foams which comprises reacting and foaming a mixture of ingredients which will react to form the polyurethane or polyisocyanurate foams in the presence of a blowing agent comprising a partially fluorinated alkane having four or five carbon atoms and a tertiary structure. The method is advantageous because partially fluorinated alkanes having a tertiary structure have zero ozone depletion potentials, are nonflammable, and have higher solvency toward polyols.
