  • Odorant composition containing allyl ethers as odorant precursors
    Patent number: 9006168
    Abstract: The deliberate release of odorants or aroma substances is desirable in many fields of application, and in particular in the field of washing and cleaning agents. Said deliberate release is achieved by using an odorant composition that comprises an odorant precursor, which is an allyl ether of the formula (I), R1R2C?CR3—CR4R5—O—CHR6R7, in which the residues R1, R2, R3, R4, R5, R6 and R7 mutually independently denote H or a hydrocarbon residue that can be acyclic or cyclic, substituted or unsubstituted, branched or unbranched, as well as saturated or unsaturated. Thus, in particular odorants in the form of an alkene having an allylic hydrogen atom, such as ?-pinene, can be released in a deliberate manner.

  • Refrigeration apparatus
    Patent number: 8992793
    Abstract: Use of a double bond-containing hydrofluoroolefin refrigerant causes a problem that it generates hydrogen fluoride by cleavage and decomposition under influence of oxygen, leading to degradation of the materials and the refrigeration oil used in the refrigeration apparatus and causing troubles in the refrigeration apparatus. It is possible to provide a high-reliability longer-lasting refrigeration apparatus by inexpensive method, by using a double bond-containing hydrofluoroolefin refrigerant in a refrigerating cycle having a refrigerant circulation route extending from a compressor 1, via a condenser 2, an expansion mechanism 3, and an evaporator 4, back to the compressor 1 that contains an ester-based refrigeration oil containing an unsaturated fatty acid as a constituent fatty acid.
