Heat transfer compositions, and systems and methods using the composition, comprising: (a) a refrigerant comprising at least about 30% by weight based on all refrigerant components of trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)); and at least one compound inhibiting isomerization of said trans-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(E)) to cis-1-chloro-3,3,3-trifluoropropene (HFCO-1233zd(Z)), said at least one compound being selected from the group consisting of d-limonene, 2,6-diisopropyl naphthalene, β-pinene, farnesene, α-terpinene and combinations of two or more of these.

The present invention relates to a composition comprising sinensal and sinensol, and to the use thereof as an aroma chemical. The invention relates moreover to the use of sinensol to enhance the persistence or to modify the aroma of sinensal or of a mixture of sinensal and farnesene.

The application relates to the field of chemical purification technology, in particular to a high-efficiency farnesene purification method and device based on a molecular distillation technology, which comprises the following steps: at least two-stage molecular distillation processes are adopted to separate raw material liquid containing beta-farnesene and an extractant, wherein the operation temperature of the highest-stage molecular distillation process is less than or equal to 70 DEG C, and the absolute pressure is less than or equal to 40 Pa. The method is operated at extremely low temperature and extremely high vacuum, the thermal polymerization of beta-farnesene is fundamentally inhibited, and high-efficiency, continuous and high-yield purification is realized without adding a polymerization inhibitor.

The application discloses application of a wild chrysanthemum essential oil effective component combination in preparation of a medicine for preventing and treating acute lung injury, and particularly relates to the technical field of biological medicines, wherein the wild chrysanthemum essential oil effective component comprises beta-farnesene, 4-terpenol, artemisia oil, wild chrysanthemum alcohol and carvomenthone, and in an acute lung injury model, the wild chrysanthemum essential oil effective component can significantly regulate the survival state of lung epithelial cells, improve the phenomenon of cell activity decline, and effectively maintain the stability of mitochondrial membrane potential (Delta Psi m). In an acute lung injury mouse model, the wild chrysanthemum essential oil effective component combination can significantly improve the pathological injury of lung tissue, and significantly inhibit the expression of inflammatory mediators in bronchoalveolar lavage fluid (BALF). In summary, the wild chrysanthemum essential oil effective component combination can be applied in preparation of an anti-acute lung injury medicine.
