  • Process for obtaining carotene from palm oil
    Patent number: 5902890
    Abstract: Carotene is recovered from a native fat or oil in five process steps in an economical industrial process. The native fat or oil is catalytically reacted in known manner with an alkanol containing up to 4 carbon atoms to form fatty acid alkyl ester and glycerol. The ester phase of the reaction mixture is subjected to distillation to remove the fatty acid alkyl ester. The distillation residue obtained in the second process step is saponified, carotene is extracted from the product obtained in the third process step and the extract phase is concentrated by evaporation. A yield of at least about 80% is achieved. At the same time, a fatty acid alkyl ester suitable for further processing to fatty alcohol is provided.

  • Filling compound
    Patent number: 5902849
    Abstract: A filling compound for electrical and optical equipment in the form of cables, connectors, plugs etc. and to assemblies thus produced, is provided. Electrical and optical equipment in the form of cables, connectors, plugs etc. have to be protected against harmful influences penetrating from outside, particularly water, and also against mechanical damage during laying or as a result of exposure to heat. The filling compound is based on a stellate substance, i.e. a substance having a branched molecular structure in which, ideally, 3 or more branches, more particularly polymeric chains, radiate from a single branching point. The filling compound is flexible at very low temperatures but, on the other hand, does not run out, even at extremely high temperatures.
