    摘要： The invention relates to a cosmetic or dermatological composition containing at least one precursor of a substance whose active form is sought for its cosmetic activity. One of the applications of the invention relates to compositions capable of rapidly imparting to the skin a color similar to that obtained on prolonged exposure to ultraviolet, solar or artificial radiation, while at the same time avoiding the drawbacks of such an exposure (erythema, burning, loss of elasticity, appearance of wrinkles, premature ageing of the skin, and the like).

    摘要： A description is given of the use of asymmetrically substituted urea derivatives of the general formula (I) where R1 and R2 each independently are a linear or branched aliphatic hydrocarbon radical having 1 to 4 carbon atoms as accelerators in combination with dicyandiamide as latent hardener for epoxy resin systems based on unhalogenated or halogenated bisphenols of type A or F and also based on resorcinol or tetrakisphenylolethane. The advangages of the inventively proposed accelerator/hardener combination are, for example, the excellent reactivity and very good storage stability. Moreover, the mechanical properties of the resins cured accordingly are likewise outstanding.

    摘要： The process for preparing propene and hexene from a raffinate II feed stream comprising olefinic C4-hydrocarbons comprises a) a metathesis reaction in which butenes present in the feed stream are reacted with ethene in the presence of a metathesis catalyst comprising at least one compound of a metal of transition groups VIb, VIIb or VIII of the Periodic Table of the Elements to give a mixture comprising ethene, propene, butenes, 2-pentene, 3-hexene and butanes, using, based on the butenes, from 0.05 to 0.6 molar equivalents of ethene, b) firstly fractionally distilling the product stream obtained in this way to give a low-boiling fraction A comprising C2-C3-olefins and a high-boiling fraction comprising C4-C6-olefins and butanes, c) subsequently fractionally distilling the low-boiling fraction A obtained from b) to give an ethene-containing fraction and a propene-containing fraction, with the ethene-containing fraction being returned to the process step a) and the propene-containing fraction being discharged as product, d) subsequently fractionally distilling the high-boiling fraction obtained from b) to give a low-boiling fraction B comprising butenes and butanes, a pentene-containing intermediate-boiling fraction C and a hexene-containing high-boiling fraction D, e) where the fractions B and C are completely or partly returned to the process step a) and the fraction D is discharged as product.
