NettetNormally a water reservoir is used for steam distillation, and thus the distillation will never go above 100°C. I was wondering what are alternative reservoirs that may be … Nettet2. apr. 2024 · 2. Distillation of many organic oils and resins requires temperatures significantly higher than 100 o C. If you add water to the oil/resin (say, 50/50), the mixture will boil at 100 o C. Well, not quite 100 o C, because at the boiling temperature, the oil or resin will have a slight vapor pressure of its own, and the total vapor will therefore ... hartfalen complicaties

This is carried out in a long container with the help of a zone heater. Important Applications. The method of distillation has a considerable history, dating back to 3000 BC. NettetDeodorization is a steam distillation process carried out under vacuum (1–5 mm) and at temperatures ranging from 210–270°C. The steam acts as a carrier that removes odoriferous compounds and results in a bland product. Typical deodorization conditions are shown in Table 1.10. hart family atlanta
