摘要： The present invention relates to the use of a process fluid with an environmentally compatible biostabilizer in a geothermal borehole. The biostabilizer is characterized in that it comprises at least one organic acid, or a salt, alcohol or aldehyde thereof, wherein the at least one organic acid is selected from the group consisting of hop acids, resin acids, fatty acids and mixtures thereof. The biostabilizer is preferably a mixture of hop extract, rosin and myristic acid. The invention further relates to related process fluids and methods for producing the same.

摘要： The invention relates to a method for producing thermoplastic starch, in which a mixture comprising starch and a polyol, preferably selected from the group comprising polyethylene glycol, monosaccharides, sugar alcohols such as glycerol, sorbitol, erythritol, xylitol or mannitol and mixtures thereof, in a quantity of between 10 and 25 wt. % of the mixture, and an epoxide selected from the group comprising epoxidised plant oils such as soybean oil, linseed oil, sunflower oil, rapeseed oil and mixtures thereof, in a quantity of between 0.1 and 6, preferably between 2.5 and 3.5 wt. % of the mixture, is extruded, the mixture also containing an acid, preferably a carboxylic acid selected from the group consisting of citric acid, malic acid or tartaric acid, in a quantity of between 0 and 1, preferably between 0.1 and 0.5 wt. % of the mixture. The invention also relates to such a produced thermoplastic starch, to a compound produced by means of the thermoplastic starch, and to a film produced from such a compound.
