    摘要: A process for the tetramerisation of ethylene under solution phase conditions is carried out in the presence of an activated catalyst at a temperature above 80° C and up to a temperature of about 115°C. The activated catalyst is provided by combining a source of chromium, a diphosphine ligating compound and optionally a catalyst activator or combination of catalyst activators. The process forms at least 30% 1-octene and a polyethylene co-product that, together with any other reaction products, remains substantially dissolved in the liquid phase. The polyethylene co-product has a weight average molecular weight (Mw) of less than 200 000 g/mol, a number average molecular weight (Mn) of less than 3 000 g/mol, and a melt flow index of more than 20 g/10 minutes.

    摘要: The invention describes an overall process for the extraction of sterols, vitamin E, squalene and other plant-based hydrocarbons from deodorization distillates of plant oils. After an esterification of the free fatty acids, then a transesterification of the combined fatty acids (glycerides and sterides) by the same short alcohol, three successive distillations make it possible to successively recover a first fraction of hydrocarbons, the main fraction of alkyl esters, then the heaviest alkyl esters with squalene. The third distillate will be used for the production of squalene and a second fraction of hydrocarbons. The residue of the third distillation will be used for the production of sterols and vitamin E. By using bioethanol, plant-based glycerol and the plant-based hydrocarbons of the process, the process makes it possible to extract each of the four unsaponifiable substances without any solvent of oil-based origin and to claim the seals of approval for products obtained by natural physical and chemical processes.

    摘要: This invention relates to novel compounds, capable of potentiating the efficacy of therapeutically active compounds, for example cytotoxic compounds used in the treatment of cancer. The novel compounds have been shown to increase the pharmacological activity of a conventional paclitaxel formulation and to make it possible to manufacture a new formulation of paclitaxel, exhibiting improved solubility, improved storage properties, and increased therapeutic efficacy as shown in the enclosed examples. (Formula I, II, III, IV, V, VI)
