摘要:The invention provides an apparatus for forming fine particles of a substance in a precipitation chamber, in which the apparatus has means to convey the fine particles from the precipitation chamber to at least one particle collection chamber, downstream of the precipitation chamber, the particle collection chamber having an inlet and an outlet separate from the inlet. The invention also provides a method of forming fine particles of a substance, the method comprising contacting a non-gaseous fluid containing the substance with a dense fluid to expand the non-gaseous fluid in a precipitation chamber, conveying a resulting mixture of fluid and the fine particles from the precipitation chamber to a collection chamber, the collection chamber having an inlet and an outlet separate from the inlet.

摘要:The present invention is directed to a method for continuous production of dihydroartemisinin and also artemisinin derivatives derived from dihydroartemisinin by using artemisinin or dihydroartemisinic acid (DHAA) as starting material as well as to a continuous flow reactor for producing dihydroartemisinin as well as the artemisinin derivatives. It was found that the reduction of artemisinin to dihydroartemisinin in a continuous process requires a special kind of reactor and a special combination of reagents comprising a hydride reducing agent, at least one activator such as an inorganic activator, at least one solid base, at least one aprotic solvent and at least one C 1 -C 5 alcohol.

摘要:The invention pertains to a process for the manufacture of disentangled ultra-high molecular weight polyethylene in the presence of a co-catalyst comprising trialkylaluminum and a catalyst which is a substituted monocyclopentadienyl, monoindenyl, monofluorenyl or heterocyclopentadienyl complex of chromium or titanium in which at least one of the substituents on the cyclopentadienyl ring carries a neutral donor function which is bonded rigidly, not exclusively via sp 3 -hybridized carbon or silicon atoms, characterized in that the process comprises the following steps in the given order: i) a solvent and a trialkylaluminum-scavenger and optionally co-catalyst are added to a reaction vessel, ii) ethylene is added to the reaction vessel, iii) a mixture of the catalyst and co-catalyst is added to the reaction vessel. UHMW-PE obtainable by this process is also claimed, as are fibers, films tapes and moldings comprising this material, and their use in penetration-resistant articles, gloves, biaxial films, cables, slings, ropes, nets, pipes and prostheses.
