摘要:
The present invention pertains to a method for the efficient production of carotenoids. In particular, the present invention is directed to a method for producing carotenoid and carotenoid-containing cells, especially astaxanthin and astaxanthin-containing cells, by generating mutant microorganisms belonging to the photoautotrophic algae of the Class Chlorophyceae and culturing same. The present invention further relates to methods of generating microorganisms producing high yields of carotenoids, in particular astaxanthin, products containing said microorganisms or said carotenoids, and the use of said carotenoids produced by the microorganisms according to the present invention and deposited mutant strains generated from said microorganisms.
摘要:
What are proposed are novel lipophilic preparations comprising (a) from 20 to 40% by weight of myristic acid or esters thereof, (b) from 20 to 40% by weight of palmitic acid or esters thereof, (c) from 0.1 to 5% by weight of aliphatic and/or cycloaliphatic hydrocarbons and (d) less than 20% by weight of carboxylic acids or esters thereof having 12 and fewer carbons in the acyl radical and (e) less than 20% by weight of carboxylic acids or esters thereof having 16 and more carbons in the acyl radical, with the proviso that all percentages add up to 100% by weight.
摘要:
A granular solid with monodisperse particle size distribution is disclosed, which may be obtained by melting an essentially anhydrous composition, which is solid at room temperature and made from at least one cosmetic ingredient. A flow of the melt is dispersed into droplets by means of a casting plate and vibration and said droplets contacted with a cooling medium, which causes the solidification thereof.
摘要:
The invention relates to a method for producing alkylene oxide addition products by reaction of compounds having a nucleophilic center with alkylene oxides in a reactor having a large inner surface. The invention is characterized in that the reaction is carried out exclusively in the liquid phase.
摘要:
The invention relates to a method for producing Guerbet alcohols of formula (I), CH3(CH2)nCHR1CH2OH, wherein R1 represents a linear alkyl radical having n-1 carbon atoms, and n represents 3 to 9 carbon atoms. Fatty alcohols of formula (II), R2OH, wherein R2 represents linear alkyl radicals having 6 to 12 carbon atoms, are condensed in the presence of carbonyl compounds and alkali hydroxides.
摘要:
The invention relates to a method for producing alkylene oxide addition products. The method according to the invention is characterized by (a) contacting ethylene and/or propylene with an oxidizing agent in a first structured reactor ('μ reactor') and (b) feeding the ethylene oxide and/or propylene oxide so obtained, optionally after purification, to a second structured reactor where it is reacted with a compound having a nucleophilic molecular group.
摘要:
The invention relates to a method for the continuous esterification of C1-C22 (fatty) acids with C1-C10 monoalcohols, C2-C5 dialkanols or trialkanols, or mixtures thereof, in the liquid phase, according to the counterflow method, in the presence of heterogeneous catalysts in the upstream reactor (1) and in the reaction column (3). Said method is characterised in that an upstream reactor (1) and a separating unit (2) are mounted upstream of the reaction column (3), in order to reduce the viscosity of the reaction mixture, and the reaction water (3) is extracted from the system by means of the separation unit (2), in order to shift the chemical balance upstream of the reaction column (3).
摘要:
The method for the production of a product by means of melting a supplied material and letting it harden, preferably a method for the production of types of glass, in particular soluble glass, in a furnace, preferably in a tank furnace, using heat recovery, is characterized in that at least one part of the heat given off by the product produced is used for preheating the supplied material. Thereby energy is saved, the capacity of the tank furnace is increased, the occupational safety is improved, and less water for cooling the conveyor belt is used for the melted glass produced.
